MOUNTAIN BIKE HANDLEBAR FORMULA | The Body to Bar ratio
Вставка
- Опубліковано 5 сер 2024
- In " Mountain Bike Handlebar Formula" Alex and Lee unpack the mystery of handlebar width. Mountain bike handlebars are a compromise between 5 elements of fit: Pushing; pulling; range of motion; stability and joint health. The ideal compromise is different for every rider but there is simple place to start and all you need is your height.

COUPLE NOTES: The 4.40 calculation is based on a male of average proportions with an upper arm angle of 20 degrees for optimal shoulder joint health and push/pull strength. This provides an estimated MAX. Going a bit narrower always works and provide more pull strength and more range of motion. If you are over 6'2 or 188cm run whatever you like as long as it feels good. Females of average proportions may find more accuracy using a multiplier of 4.26
Lee recommends to go 5% less in his Pinkbike article, which dates back to 2018. Is this recommendation still applicable? Thanks!
I was actually wondering if different skeletal structure and size (shoulder bone to shoulder bone) also play a role to the bar width. For example, I measure 22 inches shoulder to shoulder, which is also the distance from the middle of one palm to the other if I set my arms by my side.
Terrific, thanks for the female ratio. We’ve been trying to figure out where to cut my wife’s bars. She’s 5' and developing a spine hunch.
As a female rider, I do appreciate that you include recommendations for females here in the comments, but it would be really awesome if you could include this in your videos as well! If all these details are so critical to successful riding, please don't treat women as secondary or an after thought. Most mtb content defaults to males and it is challenging to figure out if it applies the same to women given our different body proportions. Where I ride it is 50/50 males/females on the trail, so please include everyone! Anyway, really appreciate the content!!
Didn't lee learn his lesson about arbitrary fudge factors to height with the RAD measurements? Also, it wouldn't even be 4.4, just use 0.44 so you don't even need to think about units. Looking forward to the video in a couple of years when he admits again he was thinking about it all wrong, but we should believe him now.
Came from a hardtail with narrow bars, never had any aches, bought a new bike a few months back with 780mm bars. For the first month of riding I had wrist ache and my inner thumbs felt "Bruised" and I would subconsciously move my hands right to the inside of the grip and I wouldn't realise until I went to change gear and had to move my hand. Came across this vid, did the formulae, I'm only 5' 6"-ish and my width came to 740mm, cut the bars down to that, and even though it's literally only an inch off each end, it's became a lot more comfortable to ride, I'm more upright, cornering feels better and I feel more in control at lower speeds...Thanx Guys.
I'm loving your work guys. I have been making good progress on my hops. Which I used to think were unbelievably complicated, until you put me right. After watching your RAD videos and this handle bar video. I now know why I find hops easier with my older shorter reach and narrower handlebar bike.
These videos are really great! I think i have searched 10's of times for information on determining handlebar width and now i came across this by chance through one of your other videos. I'm glad i did. Great video and great channel!
Use a plumbers pipe cutting tool. They are cheap and you get a nice cut every time.
Just not for carbon....
@@thesaltlick4057 Ok if it's done gently.
@@thesaltlick4057 If you use it for Carbon bars you will be very disappointed with the result.
For "carbon", it all depends on which process was used. And you can change absolutely every little aspect of a composite item production to your exact liking.
I had the chance to do a report at Look factory (frames, pedals, outer soles, aero handlebars, etc.), and those folks confirmed it : "We can make frames a thousand different ways, composite ends up being what you want... there's no obligation.".
So... unless you know exactly how this composite tube was made, just don't cut it. Don't. No !
Or ask the factory, and most times they'll reply : "Don't... the end tips participate into the structural properties of your handlebar. If you cut them, you risk weakening... then breaking, possibly.".
Unless specific inserts were used, and you receive the OK to shorten them.
Using a pipe tool gives the edge a bevel which CAN punch through your bar end in a severe accident and cause major damage. Just beware of that. At the bike shop we always use a hacksaw and a the park tool SG 7.2.
Thank you! I’ve been doing my own thing for decades. Forget the trends, do what’s best for your body mechanics.
My god, you guys are amazing. I'm having trouble fitting my mountainbike and you are helping me on the journey! I'm not there yet but this is a great recourse!
I watched this several times - it is a great video. After some experiments I left my LEVO sl at 760 (my calculated for 180 cm is 790) but then I started looking at my xc bike I have for 10 years. It has 690 bars but it has at least 30 mm longer stem compared to levo and still feels good after all the experiments. For sure this video helps in optimizing the bars and knowing why. Thanks
I don't get why the formula is based on height, what if the person is tall but has narrow shoulders or vice versa? Or if the person has long or shorter arms
Yeah it doesn’t make sense. I’m 194cm tall and my max bar width is supposed to be 853.6mm. I’m currently using 780mm and I’m thinking about making them more narrow
Because it's obviously just a rough estimate, and body height is easy to measure. Much more so than to find the middle of you shoulder joints to measure their distance. Also, while obviously there are different physiques, ROUGHLY shoulder with DOES go with body height. Also, the formula is mentioned give you the MAXIMUM bar width.
Great video guys.
Hit 50 this year and I have ordered my first modern mtb (haven't ridden for years). Used to be a personal trainer focusing on rehab and biomechanics, and I switched to pulling/pushing narrow because it doesn't hurt my bad shoulder (better mechanics) I'm also stronger in that position.
My bike will have 800ml bars, so your advice and the calculation is a must for me.
Thank you 🙏🏿🇬🇧🇦🇬
These are so informational, and funny and well produced all in one package. I always seem to gravitate to these, and think "why dont I watch more of these". Big up!
I have been watching some of your other videos and was blown away by the info in this video. Always wondered why my shoulders were hurting with wider bars and now I know. I can go back to the other video on selecting the correct bar sweep now that I have the formula for correct (starting point for the widest bar I should ride). Thanks for this eye opening info.
Alex and Lee are the best MTB UA-cam creators right now. Your videos have translated into more JOY for me on my bike! Thank you!
Thank YOU!!!
Roadie just picking up the MTB thing, this is by far my favorite channel! Thanks for all you guys do, keep it going!!!
Welcome to the dirt!!
You've offered some great advice, guys! I'm a total amateur, but anything I get into, I like learning as much as possible about it, and this video was pure knowledge. Thanks for that!
Epic work, fellas! You guys are the Simon Crafar of the mtb world! Genuine, informed, no BS. Tops!
You two are really providing great content based on new lines of thinking and science. I really enjoy watching and learning from your videos. Old dogs can learn new tricks (skills)
Our pleasure!
Really enjoying your work. You are doing a great job presenting a lot of the same topics I see on other channels. But describing them in different ways that is truly letting me learn more about my riding.
Appreciate that! We're trying to put more "why" in the mix. : )
Thanks guys, subbed, glad I found you. I was riding an older "all mountain" bike and I felt like a more competent rider, and rides were more enjoyable then. The bars on that bike had 760mm. I have upgraded to a new larger bike and haven't found riding as exciting and just realised now, upon measuring, that is is 790mm. I recently purchased a hardtail for different riding and for some reason I prefer riding that bike, that is with a 695mm bar. Now I know geometry is going to be a variable as well, but as someone who is 168, it sounds like I will cutting my bars. I'll go down from 790mm to 760 as a starting point and see how we go from there. Thanks again!
man, I love your videos, I'm so lucky to find your channel before start a mountain biking.
Lee is a gold!!
keep it up man, 🤘🤘
Your formula is accurate for me. I am running 760 but unconsciously moving my hands inwards. I am 168x4.4=739.2 but i think i'll leave it there. I will adjust my brake lever inwards. Always great content! Keep it up! Thank you.
YOU GUYS ARE THE ONLY ONES DOING THIS KIND OF CONTENT!!
My MTB has changed my life, your information has changed my riding!! Keep the sizing stuff coming please and thank you!
Bikes are magical.
Lee: "He's always wondered why I'm so frickin strong"
Alex: "I've never wondered that once"
LOL
I've wondered a lot of things about Lee but that wasn't one. But that's not to say he isn't strong. Pretty much a beast. : )
That was funny.
Thank you for your videos. they are very educational.
I'm 47 yrs old. and I ride the trails about 2X a month ( family and Dad stuff) I'm very exited to try your tutorials on all of this .
I get exited and go outside about 9pm and just try the things you put on UA-cam. Thank you. Working on my bunny hop and I'm trying the Wheelie how to video.
That is awesome!
I was watching this between sets of working out, and decided to measure my estimated bar width (792) compared to my bench press and military press grips. Appropriately enough, it landed right in the middle. Another thing for shoulder health I think about is sometimes I see "attack" positions that have the elbows up so high that the shoulder starts getting into internal rotation, which can cause all sorts of problems. Be kind to your rotator cuffs, they're little and wimpy, but essential.
Thanks Alex, this is perfect(kind of like your frame sizing video saved my butt) timing! I just received my new carbon bars when this video came out, I was assuming I would be at 780, but after doing the calculations and testing I’m at 760 and living it!! Thanks again for all you do!!!
Damn... your channel is my new go to for all things MTB related. Started riding again last year after many years out of the sadel. I am soon 45 and I find your video koncept to suit me perfect. Got a new Kona Process 134 last friday .
i really love and appreciate this channel.keep it up guys...good work 🤘
Doing such good work boys. Love it
Upgraded my XC mtb and noticed handle bar width was 780 mm, up from 700 mm on previous bike. As a lifetime time weightlifter, the closer grip feels more comfortable and stable, and from experience, open shoulders lead to injuries. I cut the bar to 720 mm. Feels great!
My XC MTB came with 680mm and I went and put on some 800mm today and it was not comfortable at all. It lost its responsiveness.
Did you notice the same thing?
How tall are you?
great videos, i started with RAD then again this caught my attention, as a newbie everything in mtb is confusing especially with the proper bike and body geometry, thanks to you guys, very informative and enlightening.
This channel deserves all the subscribers in the world. Such a joy to watch. I'll be 40 this year and just got myself a nukeproof scout 290 comp and I'm recently getting back into trail riding. The 800mm bars feel ok (I'm 177 cm) but I struggle to control the bike fully. I am going to move my controls and make adjustments until I see what's best. Thanks for all the info you guys are putting out there.
You bet. We love our subs!!! We got the best ones. : )
One thing worth considering and a great addition to your formula would be where TOO NARROW starts to happen. I don't suffer from stability but I do find that I get a bit of elbow pain on a bar that isn't adequately wide.
A couple of years ago I brought Lee's book Dialed and got my bike setup as close as I could to his recommended dimensions with a different stem and spacers that I had already and a new bar and it all feels great especially when out the saddle and 'hinged' into some trails... so I would advise anyone to try what's in this video and the previous one covering fit. It sort of goes against what magazines and other sources seem to be saying but in all honesty it works... and bar width not being stupid wide is even more crucial when you're 56 like me 👍
Bought a bike last year. Really wish I had found this channel before, but luckily it turns out the bike almost fits me perfectly when I bought it... No wonder I like it so much! Probably could use a slights smaller stem to fit my RAD measurement better. Keep up the great work!!
Probably the best video I've ever seen on this subject. Well done!
Very very interesting. A great video. I'm probably too wide as I'm getting twinges in my shoulders, will be checking bar width out this weekend.
Great content as usual. I've been playing around with bar width recently, and the points you discuss make great sense.
Glad to help!
Wow! This is awesome. I was wondering if my 800mm bars were too wide, but now I know they're not. I'm 185.5cm tall and that works out to about a 816mm bar max. It gives me confidence in my equipment choices. Thanks!
Best description of handlebar width I've seen on YT yet. Super helpful. Thank you!
Dead on once again. Next up, you should do a segment on stack height
I’d like to see that paired with this video
I'm in on that too! I'd love to hear their take on that.
gotta tell ya guys... i took this advice and cut my bars down. my izzo came w/ 760's. which is acceptable for a M frame. at 66" or 167.64cm i came up with 737mm bars. i rounded up to 740mm. just that little cut w/ an 8° sweep made a lot of difference. mainly, less fatigue and cramping in my hands.
now both my bikes are running 740's and it feels pretty solid. thanks again!
Right on!
Nice work guys. I find this topic very interesting. Thanks for the video
This is great. I have been riding 780 for a while now. I am 6.1 with quite a long arm reach and wide shoulders, so I followed the trend and went with the widest bar I could find. I have been feeling like my bike is not working properly, balance was way off whenever I got air time. Cornering was real sketchy. Something always felt off. I never questioned my bar length, and kept trying other things. I thought it was just me trying to get back into mtbing at 49 years of age, and kept pushing myself to just get it right. Funny thing happened the other day. When I first got my bike about a year ago, I had a pair of bars that I cut down from 800. I was trying to get them to 760, but I messed up and cut them to 740. So I shelved them as rubbish, and bought another set, 780, that I kept. The other day I thought, lets try swapping the 780's for my old 740's. I swapped them out, and rotated them a bit more forward than I would normally run. What a difference!! I cannot believe how good the shorter bars feel now! Bike feels way lighter and poppier. More balance in the air. I feel so much more confident in cornering as well. Such a small change but such a massive difference. Loving my new setup!
Good comment.
When I've switched to a new set of grips without "outer clamp" (Bontrager XR Trail Comp instead of Lizard Skins Charger), immediately noticed that it feels like I'm riding a wider bar. After a few rides, decided to cut the bars, and get the same "grip distance" as before. It was just 5mm per side, but noticable difference. So I'd also add that you need to take into account what grips you are going to use, as some might get your palms to a different position...
Awesome like the rest : I especially liek all those videos on size/fitting, this is so much helpful !
I still use this video over and over again. Still never saw anything more relevant so far. Thumbs up forever
Big big thank you guys, I am just seeking for changing my old 620mm bar, and I am 181cm tall so... R.A.D was incredible and now perfect video at right moment with greatest people?, Man..., F*..ing awesome, regards from Spain
Thanks Jesus!!
Hey Jesus, you may also consider to reduce the stem length. Which gives you a more direct control of the bike, which comes with the cost that it gets more flutter on gravel. Depends on your preferences
This immediately went way deeper than I expected. Classical music and math 😳
Hahaha. And you forgot to mention Vitruvian man in the thumbnail. : )
@@JoyOfBike just noticed that. I clicked on the vid before even checking out the thumb 😂
Thx guys! Now...to the garage! To measure ALL the bars! 🤓🤙
@@fasterwheels Cool idea to use your front brake rotor as your profile photo🤘🏻
Great info. Thanks for including the women’s formula. I see lots of discussion on accounting for other body measurements, but the way I see it is the formula just gives you an idea of where to be. Add in the physiological clues and twitchiness, and you find the right width. I like it! My stock HB is 640 mm but the formula puts me into the 740-780 range. I’ll have to play with that.
I'm 5'9 and run 680s on my trail bike. Love them! In my area there are a lot of tight trails with narrow gaps between trees, the short bars are great for dealing with that.
Since pulling is the main power move involving the bars, I like running my bars at 760mm, even though my calculated max is 810. Feels awesome.
I’m in philosophical agreement with this. Too much focus on width and to what end?!!
Another great video packed with stuff we should know, but don't! I'm personally a little sick of how wide my bars are on my newest bike and based off the formula I'm running at least 20mm too long. I am more used to the handling by now, but at first I had a really tough time with bike control. Now I just dislike how often I come close to clipping the bars on trees and stuff on narrow parts of my local trails.
Intuition and math coming together. Time to make a cut. Measure twice!!
You are my favourite go to MTBing on UA-cam. Many thanks guys you’re Awesome!
Wow, thanks!
Thanks for the great series of videos, very helpful and so well explained.
Glad you like them!
I am 6' 2" and did the push up method years ago and came up with 740. I have been riding 740 ever since and love it.
Great!
You wound up in a good spot!!
The other benefits to narrower handlebars are that you can squeeze between trees better on the trail and get your bike into and lay your bike more easily on its side in your hatchback or SUV cargo area.
Great video guys. Have a new carbon bar and was looking for details on better for your body bar widths. Good stuff! 🙂👍🍺
Super helpful. I just got a new bike. After my second ride yesterday my upper traps and back of shoulders were noticeabley sore. But I had zero idea where to begin with proper width. Thanks for the helpful and well explained info.
Scary how well that calculation works. I've been on 720s, 740s and 760s over the past decade, (and up to 820 on demos 😮,) but the calc says my max is a skosh over 780. Sure enough, the 780s I've been running the past few months are the best feeling I've had.
Bend and sweep make a difference as well. Renthal's relatively shallow backsweep feels outstanding, whereas some of these 10 and 12 degree bars, (BMX freestyle is really bad about this,) feel horrible to me.
Thank you guys. My last bike came with 800mm bars. I had never used such wide bars but wanted to try them out. They felt ok just riding around the neighbourhood but as soon as I got on the trail I hated them. I left them alone to see if I would get used to them. A few days later I went to a trail system about 40 mins away and on one of the trails I ride often I got stuck twice trying to ride through the trees. I went back to the car and cut them down. I brought a hack saw just in case. No more knuckle dragging.
Such a helpful video to augment the information on your site Lee. I should be at 770 mm, just got my new bike that came with 800. Gonna start sliding my controls inward and ride the same tech trail to experiment.
Thank-you Lee and Alex for a definitive guide to handlebar length. I will be cutting the 800s to 770s. I already have a 770 setup on one bike and it works great!
My height 5.7inch handle size?
i'm 6 5 (194cm) and have gone down to 770 in the last few years. it's perfect. optimum control, optimum comfort.
6'5" is just over 195cm - I hate it when people take 1cm off my height!
Interesting, since formula from this video suggests your max is 860mm
Yep, see, you prove my point! - Height in CM x 4.00000000
similar: 6'3 here and i do have 800 and im thinking of 780mm to test out. 800 feels "apey" to me
@@tehalexy 6'3, 275lbs, 820mm, feels beautiful.
Thank you, I’m 5’9” and was riding with 800mm bars. After watching this video I cut them down to 770mm. It feels so much more comfortable to ride now.
Great to hear!
Did u measure your handle bars before you cut?
I'm 5-9 as well and my Cannondale Scalpel came with 680mm and today I put on 800 to test and it felt very uncomfortable and the bike lost its responsiveness. It will have to cut them for sure. The formula shows 770. I will start from there...
What was the outcome on your bars?
@@Dopeassbikevids no I did not. They were pre marked at specific lengths so I trusted the measurements on them
@@Whatsthe_411 770 feels good and my arms don’t get sore anymore so I stayed at that width.
I’m 5’ 9 and I just cut my bars down from 780mm to 740 right before watching this video! I was having too much trouble getting in between the trees in the trails with the 780s… clipped a tree and ate dirt on my last ride! Great video! Just subscribed!
This with the bike sizing video are absolute gems. I appreciate that the focus is ensuring the bike is set up according to the biomechanics of the rider. For cutting bars, pipe cutters from a hardware store are a good option too.
I recently got a my first FS bike and had an anxiety inducing moment when I nervously went to see if it was properly sized (used the lying on my back method). It was (direct-to-consumer, they had me submit multiple body measurements when ordering).
Now I'm interested in handle bar width as well. I like the suggestion of narrowing the grips and brakes/shifter and then cutting. Would be easy to do on trail with a multi-tool as well.
Keep up the great content. Seriously, when are we going to get a Patreon? You guys are absolutely killing it.
I'm working on the Patreon!!
Appreciate you!!! I don't think I will do one. Buy a shirt perhaps? Lee will be doing a Patreon for himself.
I went back from 780mm to 760mm bars as they felt much more comfortable. My hands sit about 15mm in from the ends. I did the calculation = 727mm so absolutely spot on! Lee really does know his stuff!! 👏 👏 👏 👍🏻👍🏻👍🏻
Spot on? 760-12= 745 against 730. We talk about centimeters, so I think 1,5 cm is quite a difference.

@@brandonreimer184 awesome👌🏻
Think about it...2 people same height=same bar width, right.... wrong. They could have totally different shoulder width and arm length, and the reach and ETT on their bike differ.
The formula is, with any common sense, utter nonsense.

Wow, thank you!
Very informative info!!! IT's exactly what I need to know. Thank you guys!!!!!
Holy hell, i'm 5'7" and ride 780mm. Time to work my way down, new to riding but not new to shoulder surgery. Thanks guys!
5' 7.5", running 720 mm bars. Started out at 740. Will probably go down to 710 due to rotator cuff injuries.
Some real benefits to narrower are stronger and FASTER pull. And more range of motion. Bring on the table tops!!
@@JoyOfBike i hope so, i'm just learning to jump and am able to clear some sm/med tables! Been working on my row, anti-row :)
Man, I'm also just over 5'7" and switched over to a 45mm stem and 800mm bar last October. Not twitchy enough IMO; resulted in 2 titanium plates, 4 screws and 5 pins in my left wrist later that very same day!
I just got back on the bike last week. Will pull the controls in and try again!
This was really helpful. I've been on 780s for a couple years, and though I'm 6'1", they've always felt a little too wide. Now that you've addressed the long bike and wide handlebars trends and how they impact riding and fit, how about head angle? It feels like we're being told that slacker is always better, but I'm skeptical, especially because of the narrow, twisty, undulating trails in my area.
We'll probably get into that. But slacker isn't better -- it's different. It behooves us to pick bikes that fit our bodies, riding styles and terrain.
Slacker is ALWAYS better!!! (That was my April fools joke for this year)
That was sick dude ! I stay in some Airbnb's right across the highway from there and will be bringing my new bike next time I come over. Thanks for your video.
Subbed! That is BIG, one of the 1 per 365 days vids that is actually INFORMATIVE! WOW! Great!
There are other factors - riding style and terrain; being able to fit through tight tree sections. I went from 800 to 780 and was better off. Also, besides just height, I find shoulder width is important to consider.
Shoulder width is DEFINITELY important. I'm 5ft but due to playing football (US) I have very broad shoulders.
I would imagine shoulder width is THE measurement to base things off of. Perhaps there's some rough correlation between increased height and increased shoulder width, but it's not like we all have the same proportions. Otherwise I wouldn't be so high on the ape-index. :D Also, I'm 6'2" which is 188cm, and I absolutely shouldn't be on 827mm bars. :P
183x4.4 is 805. I started with a fatbar at 800 and progressively went down to 760.
Im also 183 and currently riding (XC) with a 690mm bar, I bought a used bike and this bar came into it. I'm looking for a new bar in the past two weeks, I'll go straight to 760 once you said it, I've ridden a friend's bike with a 780mm bar and it felt veeeeeery awkward (due to the lack of twitchiness) but kinda good at the same time (the feeling of riding with my chest open), maybe 760 will work nice for me too
@@danielribas1109 I have a 750 bar with a different rise that I also use.
This is what im waiting , thnk yu smart guys ✌
I'm glad to see thought put into this. Too many reviews are of the "super-wide for super-ride, dude!" variety, and they just sound like ads to buy new stuff that they KNOW will need to be replaced at some point. This applies to all kinds of components -- it used to be "you gotta go super narrow rims" then "you gotta go super wide rims". Same for tire pressure. Same for number of gears. Same for ultra-small cassettes that wore out, but then we got over that nonsense only to get pushed back into it with 1x setups. And so it continues...
Much of it is MTB fashion for sure. I'm glad bars are available in wider sizes than years past but it's funny the way riders are focused on width and pushups and willing to sacrifice pull/hops/range of motion. I think it's because the number one fear is OTB and they don't realize most OTBs happen right after a mistimed push!!
How bout a bar length formula based on shoulder width ( jacket size)? Also, the sweep angle needs to be part of the formula. If a bar was straight, it could be equal in length to shoulder width, but each degree of sweep allows for a longer bar. This is so dang important! Thanks for the vid!

Lol ypur knees can bend pedaling &efficientcy functions just fine low seat. Lol satan teaches place head 6 feet from pavement, give tiny bars so now u a sky scraper &taller they are thmore easily they fall. Lol. I taught people how 2sit on bike 1980"s. Graeme Obree built bike matching my specs &30 guys broke hour record using my specs.
Lol my seat is slammed down as LOW AS I CAN GET IT. This raises your bars essentially. So u NOT bent over but LOWER TO THGROUND 4ridiculous STABILITY &AERODYNAMICS.
U will realize 1.5 mph at 21mph top speed electric motor as such even tho u upright but head several inch lower..
WIDE BARZ LOW SEAT, SEAT FORWARD, BARS IN CLOSE 2U PERIOD.
Worlds best basic e bike bicycle design is used by me exclusively. This will not see production ¬1 person will ask 2c it in comments. Wide would they? They are pharisee tares. Computer animations. Know it alls.
Fact.
All E bikes are absolutely deploreable contraptions built by Lucifer boys.
All manufacturimg &non humans are controlled by Satans BEAST cmputer. That computer revolves around me as its epicentre arch enemy.
Meanwhile, all thworlds problems can be solved in thgarden. And 4godsakes sell your stable of 230 horses.
I agree. I am quite short but have wide shoulders so the length based formula doesn’t work for me. Another thing I missed was twitchiness can be adressed with a longer handlebar stem.
I have found its Basically Your Inseam ..... is For Me Anyway 😎
@@darrinkulyk9560 for my it's a d1ck length basically
Awesome video. I stepped up to 785 about 2 years ago and it feels perfect. But at 203.2cm I should be running 894mm! Lol I'd never make it down the trail running that wide. I can barely squeeze through some trees as it is.
I'm 198cm. What sort of stem have you got? I'm trying to decide if I need to swap mine out. I ride a Whyte Hardtail
65mm length, but recently changed to 60mm riser bar. The riser bar has been game changing for me to get my fit right
@@sixate I just put a Renthal 40mm rise bar. They are 800mm. Feels much better. But I feel I need to do one more tweek
I'm 195. My brand new Trek EX8 XL has 780mm bars and I've been getting wrist pain, so considering reducing 10mm or so. The sizing factor started here makes my ideal size 860mm?
Very informative video. Alex and Lee making some more great content, keep it up!
Thanks!!!
thx so much for this work! Keep it up
First!!!!
Edit. Just finished watching. Hands down your videos are all about maximizing fun and optimizing ride. Kudos to you both
Thanks Mike!!!
Just a thought, given everyone's body proportions are different, how about any equation based on shoulder width instead since it dictates push / pull comfort. Great content Alex and Lee, cheers!
Also ape index will be different too..
The multiplier assumes average shoulder width, upper arm length and hand width.
There are more detailed ways to assess optimal bar width, especially if you have special proportions.

@@lee_likes_bikes Thanks Lee. btw I have your book Mastering Mountain Bike Skills and smiled when you referenced the pushup test in the video. I'm a fan of your teaching, thanks for the joyofbike trial.
That's what I'm getting at
AWESOME vid man... finally some real useful info!!!! thanx so much i already knew something was a foot in mtb its like this with many things like crank length and others... Keep up the amazing content u guys are great....
Glad it helped!
And again... great job guys!
Hi Guys, How do you get the numbers that you use to calculate R.A.D (2.5) for bike sizing and now 4.4 for bar width? Just curious. I have used the RAD calculation and it works.
I am really curious to see if the bar calculations will work for me. A year ago I changed my bar length from 760 to 780. A few months after I developed headaches after my rides, about 2 hours after riding to be precise. I never thought it could be because of my bar length. I am going to shorten bars and see if it makes a post-ride difference.
Great question. The handlebar calculation is based on average proportions and an upper arm angle of 20 degrees with the hands directly in front of the elbow.

Loving these sizing videos. According to Leetonian calculations, I should be able to go up to an 820. I ride a 720 because I've always preferred narrower bars. Must be my inherent beanpoleishness.
Wow. You are a handlebar unicorn. Consider experimenting with 750-760
@@JoyOfBike Well, the bar I replaced was a 755. Maybe I'm just weird. I'm used to it. Being weird, that is.
@@JasonFoxLCB Weird just means not following the crowd. I'm a fan of that! I ride 680 ish on my BMX!
@@JoyOfBike That's one reason I went into advertising. If only advertising still wanted the weirdos. But I digress. Back to the trails.
I’m the same way. 5’10” and run narrow. My bike now I increased to 720. Feels odd like my control is slow motion.
It is funny that I bought a used ht and came with a 800mm with minimal rise. now I run it with a Spank vibrocore one wich is 777mm wide and I feel it better. Thanks again for your content guys! You are amazing people. Cheers from Chile!!!
I love this video so much... Subscription and like wasn't enough so I had to comment as well.. great quality technical info. Thank you!
Awesome stuff!!! I’ve always believed max wide didn’t make sense. How could it possibly? Oh back up. Ten years ago wide bars were 720 and that was an awesome shift. Now that’s considered narrow and bikes come with 800mm bars and stickers that say “designed for properly wide bars” wtf? I have short people come for lessons and they look like they are spread for a pat down! All that to say, I’m 174cm and have 720mm bars and pretty comfortable. I’ll try slightly wider at some point but I won’t be shamed into keeping them wider if I don’t like it!
This estimates a MAX for shoulder health. Keep with what you have if it's working.
@@JoyOfBike oh absolutely, that’s what I was acknowledging!
After sharing this my friend texted “Great vid. Although, knowing just a tiny bit about biomechanics, it's my opinion that bar width should be calculated according to shoulder width instead of the person's height. Someone who is 6'5" can have the same width shoulders as a 5'9" person. Using overall height seems an over-simplification. Kind of like going with BMI instead of measuring body fat. It just doesn't take into account different body types. That is all...” 🤔

@@lee_likes_bikes Thanks for the incredibly FAST and excellent reply. And thanks again for showing me HOW to HOP for the first time in 25yrs of riding after just 20 minutes trying at age 68!
This channel is kicking so much ass! Thanks for the great content!
Heck yeah!!!
THank you for affirming what we already kinda knew! Good video!
Great video. Blake is the man btw. Always makes ya smile. He's a top bloke.
He's a joy!
I think a simple way to look at bar width is to look at the "direction" your forearms are pointing when standing on the pedals in a moderately aggressive "ready position", which you would be in descending. Optimal width your forearms are pointing relatively straight forward. You can see Lee in this position on his homepage near the bottom, when he's on that berm. Too wide and your forearms point "outside", which is a weaker position and hard on your shoulders, too narrow and your forearms point "inside" and your elbows are really bent, which is also weaker. Cheers.
Great info. Thanks for sharing it ! I will recheck my width right now .
Love the vids, guys... keep em coming! I'd like to see a backsweep/upsweep video like this one as it relates to muscles worked and possible shoulder pain at different angles.
Good idea!
I run 800s but I have crazy wide shoulders, buddy of mine is 6"4' and I'm a good 4 inches wide than he is, I feel like shoulder width is more important than your height
