How wide are your tyres? (or _tires_ !)
GMBN Tech i ride a hardtail and my new tyre\tire is 26×2.35. (Maxxis high roller)
2.3
27.5 x 2.3
27.5x2.25
2,5 minion DHF up front and 2,35 maxxis aggressor out back with 27,5 inch wheels
3:51 ..thank me later
It's later.. thanks ✌️
@351
3:51
I'll thank you now
Thanks
I just wanna see the answer to the question in the title can u guys just add a time stamp to that
Yeah fair point honestly
It is always at the end of the video
4:00 got u homie
Really informative Doddy. These shows get better and better. Really appreciate the hard work you must be putting in to produce this material. Cheers.
As a roadie, I enjoy these every week! Doddy is so informative, and doesn't just answer the question, but gives personal insight that people might not have considered otherwise.
Keep up the good work!
When you guys name the video some title that is ONE of many questions answered, the least you can do is add a time stamp so viewers can jump to that question.
What's the point of making a whole video then...
@@Albkiller22 well whats hes trying to say is he most likely searched for a video to see the right width of tires he should be running and wants a direct answer instead of having to watch the whole video. So the whole video isnt pointless but i would be nice to get a direct answer instead of having to watch or search through the whole thing which i what just happened to me.
@@epicalty8474 yeah but they earn money with watchtime so jumping to see a 1 minute part doesn't really support the channel
Giuseppe ahh your right that makes sense
@@epicalty8474 that makes sense if you really like their content and want to support them like I do
Doddy, you are the Oracle of MTBs. Thanks for all the info and researching those bikes for me. Much appreciated. Love the look of the Whyte by the way, but you're right there's nothing wrong with the Yeti, so sticking with that for now. I demoed a YT Capra with 650b wheels and loved how it rolled over the terrain and my hardtail is 650b too.
Doddy, absolute legend! I’ve enjoyed reading your work over the years and no less enjoyable in video. Really informative and useful info coming out of your videos mate. Top Man!
Best show our there!! Awesome work Doddy... You can really tell how much effort you put in!! Keep it up!
As always, great video Doddy.
Great vid as usual, great selection in the recommendations. Love my Whyte T130s, never let me down.
I love my Orbea Occam tr m10 2018. Just got it and love it. Light, fast, and playful. I also have a spare wheel set in plus that fits on the frame depending on where I am riding
And again a great video on GMBN Tech. :-) Thanks, Doddy!
Doddy, soooo much content, mind blown! Thanks as always!
i'm really glad that you, Doddy, master of bikes, mentioned the Orbea Occam.
i can't wait untill next week when my Occam will arrive :D
Im running a medium cage XT on 10-46, works perfectly!
Ahhhh tecky tecky tech tech... This is what GMBN should have been like from the start boys. Keep up the good work Doddy. I feel like Johnny 5 - "input input!"
It would be really helpful if you all had your questions with timestamps in the video description. Thanks for providing such great information!
I like the Goodyear 2.6 Escape on the front, the cornering teeth are a bit small but it looks better for durability. The sidewall support at low pressure is tough to beat.
I really resonate with what you said about the getting the biggest frame you can get away with. Even as a medium size rider.. This video has me seriously questing my choice of a size medium frame on my new purchase. Even with a 60mm stem w/6 degree rise and 40mm rise bars I still feel I'm over the front end with the reach too short. I'm 5.8 and and purchased a 2020 Ragley mmmbop with some modern slacker geometry.. bike is awesome maybe should have got a size large.
Great at explaining things this guy. Thumbs up
The first question on the nukeproof i have the same bike and same issue i took it down to my local shop and it was a collapsed bearing
Top info good man thank you!
I like how Doddy seemingly pulls various items out of his ass
I’ve got a Whyte t130s. It rocks!
Really liking format for GmBn tech..Stellar job on air inforks and spacers.Best explanation I've seen..Question. Having rebound bouncy is it posibly to use it as a asset..for jumps bhops etc.Like a trigger after preloading shocks ...With the right timing you use less energy for these mtb techniques..Learn to tame the beast ...as it were.
2.6" Smart Sam is a great tyre, rides really smooth on the road, plenty of footprint on the trails.
I Run 2.40 / 2.50 Excellent Traction To Weight Ratio 😎
Commencal meta tr is a super underrated trail bike, with agressive geo + it’s a direct sale brand (the top model is $5000 AUD and it comes with a lot of good stuff)
Great presenting and content!
A medium cage 11sp XT RD-8000 GS will even run with an 11-50 tooth cassette in the back, although the chain tension is near borderline, and the B screw might reach its limit. You can pimp it with several upgrades though (Wolfcage, Goatlink, Garbaruk cage, etc), which all should improve things. I was running the XT SG with the massive 50 in the back for some time though, and it did work. I eventually upgraded to a Wolfcage though to improve shifting performance.
Thanks for these qna the tyre tip is a good one will look at the contys
Great show Doddy!
Thanks, great one.
My tires are 2.5 Minion DHF front and 2.3 Agressor on the rear on NOBL tr38 wheelset. But about the gear box. Wouldn't it also feel better having all the weight centralized and low (for handling purposes) i would love to hear doddys thoughts on where the weight is distributed
Some sewer covers in my town are across the street with longitudinal cuttings. If one ride a street bike it must pass diagonaly or the front wheel get stuck between. And its dangerous to do that because you cant always go sideway in traffic. So i chose an MTB for commuting in town (6km) and for fun ride. At my old bike i replaced 2.1 default with 2.2Continental. At my new bike i still use 2.1Maxxis but with lower pressure.
I could watch doddy talk about tech all day,.
With yer old chap out?
Phantom Big Balls hahah funny that bro
What the hell am I missing? How come you blokes only have 39K subs? I've learned loads from you, and by now you should have millions of subs!
199k
Hey doddy, in regard of gearbox bikes you should definatly have a look at the effigear gearbox and cavalerie bikes. I really like the idea of the pivotpoint of the swingarm beeing coaxal with the sprocket. It would be the only way I would consider a gearbox on my bike. This combined with a low mounted rear shock would be perfect in regards of weight distribution.
27.5 x 2.25 Schwalbe Smart sam, will try it tomorrow.
Love the seagull at 14:37 :')
Great video again doddy
i ride 2.5" everywhere, except for my dirt jumper which runs on 2.4" Holy Rollers - that's the wide version and coincidentally the widest tyre i could squeeze in the rear anyway
Hey Doddy, loving the Tech show and think you're doing an awesome job so keep it up!
I'm a tall guy too (6'4") and my Remedy 29er has a Reverb dropper post with 125mm of travel. I absolutely love my dropper post but feel like it's not quite tall enough for me. I'm considering a longer travel post, but my upgrade list for this spring seems to be getting longer with some other items wearing out (shoes and tires). I'm wondering if you think the upgrade would make a major difference or if I'm not really going to notice. Also, what are your thoughts on some of the lower price point dropper posts, like the Brand-X or any other recommendations you may have.
Awesome stuff :)
Good show as usual
yes different types of drivetrain video would be awesome , hub gears anyone????
Doddy , you’re overall knowledge and realistic advice seems to be quite extensive..I love hearing your take on things. Kudos👊🏻👍🏻
I Love the New 2.6 Specialized Butcher Gripton Grid @ 20 PSI for only $60
Great show.
very useful advice, having a fatter tyre at front. Thanks
#askgmbntech Could you explain better positive and negative air chambers in suspension and what the differences and what differences it makes in suspension behavior (e.g. more negative pressure). Thanks, love the gmbn tech channel!
Hi Doody, love the content. Read a review on a pinion gearbox. Would love to know your thoughts. Are they going to be the next big thing? DI2 comparability? Lack of rear mech etc. Thanks, mike.
#askgmbntech For the shifter script you could also look into thicker chains and internal gearhubs like a nuvinci hub or a shimano nexus/alfine, maybe with a chain tensioner.
I run up to 3 inch (77mm) and like to ride 50 mm on my touring bike.
At more than 110 kg I need the stability of a wide tire on multi purpose trail at slow speed.
Great work guys
Thanks CMOOREtbay !
Hi Doddy, I love how you pull stuff off Blake’s bike when he’s not about. Suggest stripping his bike like an exploded drawing and misting his parts with pink metalic fleck.😁-kidding!
Hi guys, firstly, I'm new to GMBN and love your videos. Great job you're all doing 👌🏻😁👍🏻 I have quick question, I'm riding a Northtec Gravity 27.5 (Running a Rockshox XC30 TK/27.5 fork) currently with 2.10 tyres on front and back. The clearance at the rear doesn't allow me to go any wider unfortunately and I would like to know what you recommend the widest I should go on the front? Would going 2.60 front with a 2.10 rear be advised? Or would it be out of place? Thanx in advance and keep up the great work. 🤘🏻😎🤘🏻
I'm running a minion DHF 2.5 up front and a continental trail king 2.2 on the back 27.5 wheels
The Trail King (former Rubber Queen) is the largest non plus tire I know. I think I measured it with 164mm bead to bead, which is about 8-10mm more than other 2.4" tires. Note that this is not the tire width when mounted, but from one end of the carcass to the other. Which means that this tire has a huge volume. And actually a wide rim will make the tire less tall, as it stretches out the tire and makes it wider. On skinnier rims the tire grows even more in height.
Apparently Continental has overhauled their "noble" tires (Baron, Trail King, Mountain King, etc) for 2018 with a unified carcass, so it might not be as large as before. But I haven't seen a new model yet, so I can't tell.
Top bloke!!!
You often mention doing a lower leg service on forks, however the manual for my 2017 Fox 34 only mentions checking after each ride and an annual service - nothing about a lower leg service after x hours.
Should I be taking it apart and changing the oil? Or just following the advice in the manual from Fox? The same goes for my shock.
The whole point of a dual air fork is the tuning capabilities don’t add oil, you adjust the progression with the air balance between the chambers.
Can we have a video on adjusting mechanical disc brake cables?
I think a short cage will get away with a 40t cassette if u put a derailleur hanger on your derailleur hanger lol , I forgot what its called but it drops your derailleur to where it should be apparently
I've found that as you go bigger, it is more about the capabilities of the bike and as you go smaller it is more about the capabilities of the rider. That is the feeling I get with sizing. On a smaller bike (within reasonable limits) I feel more like my bike follows me. With bigger bikes the feeling changes more towards me being the one that "follows" the bike. This makes sense. Imagine an adult riding a small 20" kids bike, the bike can just follow the adult on top, but if you put a 10yo kid in a XXL 29er, the kid is the one following the bike. I rather have a happy medium with tendency to downsizing for it to feel more playfull, nimble and agile but respecting the limits of "bike size to my size ratio"
With the question about will the derailleur fit on a wide range cassette wolf tooth make a thing called the goat link which allows a medium cage derailleur to fit on a 11 - 42 cassete
Hi doddy I’m loving the videos but I’m thinking of upgrading to a 1x on my Grand Canyon al3.9 and I have come across oval chain rings what are the pros and cons of running these or should I just stick to circular ones thanks Finn
Love your channel. Some of the best videos out there... but this title was a bit misleading. I came for the width of tire.
On the cassette question. I ran a 25T capacity zee mech with a modified 11-36 cassette to 11-42. Worked well without the need for a goat link or longer b screw. Only think to consider is maybe chain growth so yea. The “No chance” statement is incorrect. It s worth trying.
Doddy is right about the 3M tape. It's fantastic at frame protection. However, if you change your mind & want to take it off for some reason it can be a bit of a nightmare to get off. I'm speaking from experience here. So if you're going to use it try & make sure you're not going to want to take it off in the future.
For the question from @ArronHold about trying to fit a bigger cassette, I'll sugest to buy the wolf tooth goatlink. It's a little mech hanger extensor wich is screwed into your original mech hanger dropping 2cm your derailleur. This allows you to fit a bigger cassette no matter if you are running a 9, 10 or 11 speed derailleurs.
i recently did this upgrade with the goatlink on a shimano xt 786sgs (long cage). i'm running a 11-42 shimano hg-500 cassette, oneup components 34 oval chainring and a shimano xt hg-95 chain and it works great!
Or the one-up RADR cage, which is what I did to move to 42t.
#ASKGMBNTECH I love riding hardtails on every kind of trail imaginable. Because the rear tire is going to take harder hits than a full sus bike is it better to run heavier carcass tires even on flat trails? What would the downside be as far as weight? How much would a thicker tire effect pedaling during climbs and or long flat sections? Would higher air pressures create noticably less rolling resistance? Or should I settle for running a fast and lighter tire on more rough trails?
GMBN, don't you guys think it's high time you did an indepth review on different fullsuspension system to look out for when buying a FS bike and how they ride?
I've been in a state of dilema since half a year now, contemplating what to buy.
Another idea is, what are axle sizes in forks, 9mm,15mm and the other bigger ones. If my bike came with a 9mm QR axle can I buy a 15mm QR axle fork to replace it? will is fit my frame?

Question I have the enve M60/40 boost wheels how wide of tyres can I go with?
Hi great video, thank's.
Im from Quebec, Canada and just bought a Large size Trek Farley 7 with 27,5 x 4,5 Gnarwal Bontrager tires on mulefut sunringle 80mm wheels.
Id like to have a summer wheels and tires kit to discover and slowly enjoy mountain biking.
What would you recommend for wheels and tires ?
I am 6' tall.
Should I put a dropper post on my specialized chisel expert xc bike? And if yes, is there a dropper route through the frame?
The diamondback teleaseis a good 130/150 bike
I have a question... What bike do you think will be better for trail riding... canyon nueron 7.0 or spectral 5.0 as there is only a couple of hundred pounds between them. Im 5'9" and inseam roughly 34" what would your recommended bike be aswell. Thanks love the channel 👍
Damm, when you were touching that fork with your ring finger i was crying inside.
I've said it before that a two minute video answering one question that way when I search for a video it pops up. Often a search won't pop up questions that has been answered that is not related to the title.
hey could you still do that video on rebuilding the scout hub? if you’ve already done one could someone link it for me please
Have you guys had a review of those chaoyang Tires.. .
If I have a bike with a Fox 34 Float Factory fork (120mm travel) with a head tube angle of 67.2, how would the head tube angle change if I changed to a Fox 32 fork (100mm travel)? Trying to turn a trail bike into a XC race bike.
MI-XC you want to measure the length of the head tube to the floor and then take away 20mm. If rhe Head angle changes by over 10% then don't do it.
Reason I ask is because I would like to get more into mountain bike riding
Can you do a video on how to ride big drops?
27.5x3.0 and i LOVE it!
Hey doddy, I too am a big fan of long slack geometry, being a huge fan of pole, Nicolai and my favourite mondraker🤙🏼 I’m currently riding a 2016 Santa Cruz Bronson C(the pink one😉). It’s the best bike I’ve ever ridden, I do a lot of trail riding, but also street riding on it, Fabio Wilmer style, just not as good. I really want the mondraker dune RR, but with 170mm up front, and long slack geometry, I’d be afraid I couldn’t do street riding on it? Should I just get the thought out of my head and stick with the Bronson? Or could I street ride the slack mondy? Cheers GMBN Tech

Hey Doddy, I currently have stock Maxxis Ikons 2.2 in y new Giant Anthem Pro 29er, but would like to replace the front with a Maxxis Ardent 2.35. Would it fit in the Fox 32 fork? Thanks mate.
i have a rockshox deluxe shock on my trek. There is a lock out on it but i dont know if it is 2 or 3 steps. when it goes from open to closed i goes all the way, but the other way around there is like another step. It stops in the middel.
is there 2 or 3 steps on the lockout?
It seems very difficult to understand what rim width and what tire width will equal actual tire width in the end. With each rim and tire manufacturer having so many different standards. Is the only way to know what the end tire width will be is to actually mount the tire and the rim and then measure? For instance, I am curious about running a Light-Bicycle 30mm internal width rim with a 48mm Switchback Hill tire. However, my frame will accommodate 52mm maximum clearance. Will this rim and tire combination equal out to over 52mm? Is there any way I could figure this out before actually buying the rims and tires? Thanks
14:30 will certainly soon a "scott-oiler" as on the motorcycle or so
Hey Dody , broke my wrist pretty bad last year at antur ... just getting back on the bike but have the fear .. can you recommend a good wrist support/guard ? Cheers fella.
I recently installed a new Sram gx 2X10 deralliur to my bike. But when it’s in the highest gear (smallest rear cog) the chain is way too slack until you pull it by hand. Any suggestions on what to do?
#askgmbn could you please do a video on how to adjust suspension when out on the trail. For example with the Rock Shox ultimate there are so many possible adjustments. Thanks.
My 2018 Spectral 6.0 came with DHF 2.6 front and Rekon 2.6 , rear has a tube now and I just got an EXCELLENT deal on Conti Trail King 2.4 but I haven't installed them yet, good idea? 2019 Spectral comes with 2.4
I just got a Niner jet 9 RDO , I’m coming from a 26” and I wanted a 27.5 bike (I’m not a fan of any 29er I have ever ridden) and not sure if you know but the jet 9 rdo is 27.5 plus bike (that can fit 29” wheels) and it comes with 2.8 27.5plus tires on it, my tires being worn out I’m throwing a set of 2.6 DHR 2s on it, I wanted to know if there would be any adverse effects on throwing smaller 27.5 tires on a dedicated 27.5 plus bike that is capable of 29er wheels ?
I bought a Giant XTC 26+ with a 2.8 inch (71 mm) wide tire but as I ride mostly on tarmac I want to switch to a tire that has a street profile. What is the widest street tire? I found as the widest only 2.5 inch wide tires like Maxxis Hookworm. Aren't there any wider tires for streets?
My name is Jeff I do fix place on the side and getting back into mountain biking and every type of writing you think of but my question is was the big difference between the hybrid bike with a 700 C rooms and tire to mounting bike like 29 or a 27.5 mountain bike because I am converting a hybrid bike from Academy Sports to a mountain bike with 29 rims and tires instead of the 700c and changing some parts from breaking your combo to a separate braking system like a hydraulic brakes and separate gears from. 8 gears to maybe 10 or 12 gears. 800 millimeter bars with or 45 stem
