What size wheels do you have? Do you get confused with all the different standards and technologies? Let us know 👇
29ner lightweight wheels and tires for long pedally days. 27.5 tough wheels and tires for getting down and dirty
26'''x2.0'' to 2026 (at least, I hope)... ;)
PS
There are also three disc caliper mount standards, two different disc rotor mounts, four rotor sizes and two kinds of brake fluids...
Gotta good question for ya..ive got a hydra rear hub 142 and would like to use my rear hub on a new boost frame...how can i do this??
I use bolt through wheels on my jump bike, could you cover that?
1 bike 29ers with boost spacing, 1 bike 27.5+ w/boost spacing but a weird QR rear axle (but through axle front)
There is no standard! The bike industry keeps coming up with solutions to problems no one has.
Bike industry really needs to think about what they are doing to consumers..
Lots of useful information with excellent visuals and explanations. This helped me pull a lot of jargon together and now it makes much more sense. Thanks. (FYI - From an old timer letting go of his ultimate BMC 4-Stroke with 26" Spinnergy Carbon Spoke wheels for a 2020 full carbon Stumpjumper EVO Comp 29'er with 63.5 degree head tube. I'm stunned at the difference in performance; downhill and up. I'm turning into a bike-tech-geek.) Great videos. Keep 'em coming.
Where was this video last year when I tried building my own wheels! Long story short, the LBS got plenty business out me in the end lol. Keep up the good work lads, you're getting me through lockdown.
Nice job, Henry. I have learned a lot from you and Doddy about my bike. You guys made it all so much easier. Cheers.
That's awesome to hear!
Great explanation mate. Very precise and clear. Well done. I will follow and watch all your content
I seriously needed this video
We hope it helps Aiden!
#GMBNTech #GMBN Thank you for the easy to follow guide!! This made a few things finally click for me. I recently upgraded to Santa Cruz Reserve 30's. It's been the single best upgrade I've ever made. For any one on the fence about upgrading to a wider rim DO IT! I can't believe how much more confident I am with the added traction.
Thank you for making this video. This for me is one complex topic when it comes to mountain biking or cycling in general.
That is the best, easy to understand explanation I have ever seen. Thanks
Amazing! Watching this video was a lightbulb moment in my education about wheels and hubs
Thanks so much! This cleared up some confusion...and there's still so many questions :)
Great, you are a library of knowledge 😊👍💪
I was lost but because of you I now have found the explanation on all these different hubs and rims thank you so much stay awesome
That exactly what I needed
Thank super vidéo
I seriously wanted some information about wheel sizes,thank you really much!It's like you made my day.It would be more awesome if you'd upload a video about frame sizes cause I'm new in mountain biking!You guys are great.
Shahe Gjerga oh God, you just stepped into a minefield. It depends on the bike feel you want, most bike manufacturers have a size chart for their bikes, but first you have to find out what ride feel you like and what brand fits that, you will find that out in time as you ride more and try some of your friends bikes. but there is a video on gmbn I think about what size is right for you when your in between two sizes.
Thanks for providing a clear and accurate explanation of these issues, it's much needed if you don't have a circle of knowlegebale freinds.
Nice info thanks Dude.
Very interesting and informative!
You should do an episode about MTB singlespeed hubs. There is a bunch of singlespeed specific stuff and it kinda bleeds into BMX and fixed gear standards too.
Really well done HQ. If I was new to this info, I would have been eager for more graphics and detailed photos of things like hookless beads or j-bend spokes.
Well explained. Thanks
Also, great vid Henry and guys.
Very useful video🤘🙌🙌
Very educational video. I’ve just brought a new wheelset for my mtb. But was thinking about the brake rotor bein out. There’s not much ov a difference from old to new. So your video has solved my issue thanks
Excellent video
If you can’t sleep at night turn on gmbn and listen to Henry 🙈 3 mins in and you will sound asleep 🤣🤣
First GREAT topic. Second, very knowledgeable as always. Third, Very quick summary so much so that I feel many topics mentioned need more elaboration and application points for decision making/purchasing. For example, it sounds like a hookless rim is preferrable to reduce chances of burping. However I don't remember seeing rims/wheels listed as 'hookless' design. How can we know if a a rim is that style (does it go by other names) and how do we know what tires would work best/be compatible with those rims? thanks!
Running 27.5x2.6" Magic Mary f/r, moving on to 29", will also run the same tyres, would've liked to run 2.35" rear, but it wasn't an option so 2.6 is fine.
(All of this on 30mm ID-rims)
Recently went back to 26 from 29er. I just enjoy it more.
Also left out that 27.5 is 0.99 inch bigger then 26.
And 29 is 2.48inchs bigger then 26 🤣🤣🤣
Nice, the thumbnail was fixed.
I'm not sure that boost spacing for the front wheel is actually the best idea. One would think that it would weaken the fork somewhat. Also, while it may build a stiffer wheel, is that what we really want out of our front wheels? Crankbrothers Synthesis wheels are very well reviewed and part of there ethos is having a front wheel with a bit more give.
Just a thought.
The wheel whisper 😳
I plan on building a wheelset with a offset rim. Hope pro 4 boost with race face arc 40 offset rims for a 27.5 wheel. Offsets are do new to me. I need help. Angled washer yous say. I'm scared to build it now😨.
Just finished watching the video, I now need a fuckin' drink!
I just built up some ARC Race Face Offset rims. What angle washers are you referring to? Thanks!
Can I use 15x110m hubs on my front wheel and the smaller hubs on the rear wheel?
The frame I’ve got is not compatible with 15x110m hubs
#gmbn #gmbntech Good video 👍
I'm not sure if you covered it or I missed it, but I've got a Lapierre AM 4 (2019) The rear wheel 29er with 148mm boost has the rim offset with the spokes can this be swapped with a wheel where the spokes are centered? Cheers
How do I measure rear axel dimension as I'm think about an ebike conversion kit
One on fat bike would be cool as a second video
I don’t understand why Google says for my height (6’0”) 20”-22” tires would be my size, yet here they’re talking about 26”-29”
Does this mean i have to be careful when purchasing a hub for my Marz 888 RC3 Evo v2 Ti? Only the nonboost 20x110 hub will fit right?
I got a Trek Y11 bike and no tires. How do I know what tires to put on it? I measured from center to center on the wheel an came up with 22”. But I’m not sure if it’s supposed to be metric or?
I'm actually after a rear wheel 27.5 for my ebike, not sure what would be suitable for the lowest cost.
Boost 141 qr is the dumbest standard and shouldn't exist. Especially on bikes that cost 2K$.
@tittlemouse92 it's basically the same quick release principle. Same as in bikes from 15 years ago, just wider. You need to have through axle these days. It make frame stiffer, easier to maintain. With quick release sometimes you have to readjust rear brake each time you take off the wheel.
How do I find out what standard I have on my bike? Any nummber to look for, or do a have to measure myself? Great vid. Just what i needed before bying new wheels :-)
You may need to do some digging online to find out the dimensions of specific parts on your bike
@@djsercy5879 I have tried to dig around for info, but cant find the standards. I have an Canyon Spectral Al Ex 7 2017 with hope tech enduro rims and hope 4 pro hubs. Running shimano 11 speed. If that means something to you?
@@sanderblikberg7517 unfortunately, I don't know what you're looking for
m.vitalmtb.com/product/guide/Bikes,3/Canyon/Spectral-AL-6-0,19343
Same frame as your bike
Rear Dropout / Hub Dimensions 142mm x 12mm
how will i know if my bike can take a 148 boost or 157? i would like to fit an i9 hydra boost with my giant reign bike. im using a sram GX 12 speed group set.. and 6bolt rotor sram rs brakes..
Help!
Is Maxima Plush suspension oil a replacement for the normal Rockshox suspension oil?
Do I put it in the fork lower legs?
Ok linustechtips
He said "spline" like spleen and that's way more confusing than all the wheel sizes!!!!
How much do you guys recomend rockrider bikes shuld i buy one or not pls answer
Hello Experts, I have an entry level Giant Revel frame that's running on v brakes and I see that the back end can be setup for disc brakes and I have JUDY TT shocks that can be disc braked as well for the front. The goal for this bike is to use it as a city commuter without fearing about theft too much.
I've easily purchased a new front rim that has the correct hub for discs but my troubles are finding a rear wheel with a disc brake hub, im really going budget for this therefore I'm wondering about two things;
A. Can my current 26" rim brake rim be converted to a disc brake and is it better to put a cassette there instead of the freewheel ?
B. If not A then do I have to buy it all separate and build my own rim?
Hopefully somebody can help me figure this out as in store shopping is not allowed here in Ontario Canada
Why does there seem to be very little support for replacement Boost141 Qr wheels? Loads of entry-level hardtails use the standard, including mine, but getting a replacement or upgrading the wheel is a nightmare. There are a few options using Hope/DTSwiss etc premium hubs but nothing in the mid-range that's normally covered by Shimano and the like. Any ideas as I can make a massive difference to my hardtail by replacing the wheels, in ride quality and weight.
Looked at the used market?
Is it safe to use 148mm hub on 142mm frame?
I could install it, but with a bit of strecth
Haai Doddy, ek is GATVOL vir die COVID en jy?
How much of this in exclusively for planned obsolescence of parts and products?
So if I buy a brand new bike today, keep it well maintained, how long before the perfectly good bike has to be scrapped because of the absolute ballache that is finding replacement / compatible parts?
I ordered shimano m4050 rear 135mm... will it fit my 142mm rear?
It was too late when i checked. Cause i think it fits all. 😅
Which is better . Cup and cone bearing hubs or sealed cartridge bearing hubs?
is m5100 11 speed 11-51t compatible to 135mm frame and fh-m475 hubs?
I totally didn't understand a thing ! =)
can I fit 27.5 on a 26 bike? I need a new wheel and have only fitted my 2010 fox rl 32 forks I had in my shed before I got married and had kids and its really hard to find decent 26 inch wheels! I have a 2007 GT Avalanche which ive already custom built so reluctant to get a new bike
Hi. I have a doubt. I have a Novatec D042SB hub in the rear of my bike (9mm QR) and I want to know what is the biggest cassete I can put in there. Is it 10 speed? 11speed? 12 speed? I'm currently using 9 speed, but want to go bigger/1x in the future. Thank s in advance!
Hello, u can use 11/12 speed cassette on that freehub. If u buy 12 go for sunrace mz90 11-50t.
@@AndreiM1995 Thank you buddy! Certainly will be sunrace cassete, but for budget reasons, 11 speed shimano shifter and derailleur will be. The derailleur will clear a 50 tooth cassete, 11 speeds are more than enought.
@@HaveFunBikes its not a good idea to use 11-50t on 11 speed derailleur because shifting will not be smooth like on 11-46t. Better solution is oval chainring and 11-46t cassette.
Henry pump your biceps
Hi sir, My bike Riverside 500.. I want to change front and rear ARC sealed bearing hub.. What model arc hub suitable my bike.. please help.. My bike rim 28 spoke 700×35c tyre with 9 speed.
I got a 36H freewheel, 7 geared, 700CX38 cycle. I want to convert it to a freehub. Would you be able to help me out with the specs?
Yeah I was pretty confused between sizes & standards.. Eg long, short, tiny, thicc, bbc, non bbc... 😂 😂 😂
Not anymore though thanks 😂🤫
But seriously though possibly the best wheel video ever even for a roadie ❤️❤️❤️
Hi, can you help me here please. 1520-M24R32-03 this is the size of mine 29" But i dont know wich one to order online.
#ASKGMBNTECH - hello what about other sizes like in fat bikes? where the axle is more wide then in standard wheels?
What about 12x135 mate’?
So the new #GMBN in the. Confused with es sizes and standards thes mountainbikes wheels explained and the installation #GMBNTech of thes rines in the radials in thes medr Co the desimetr the forcka and compar the #moutainbiking the diferents sistems of forckags com the boss. Good learning thanks guy. Henry. Saluds from chile 🇨🇱 🤘 😀
How do you know what is compatible with your frame though?
email the company to ask
sir how to convert 142mm hub to 135mm??
Henry, I have a 2016 Salsa 27.5 + Pony Rustler with MAXXIS 3.0 front and rear. Although it rides well I would like to put a set of 27.5 SRAM Roam 30 wheels with SRAM XD Boost. Will these Roam 30 wheels fit MAXXIS Aggressor 2.3 tires set up tubeless without any problems on my Pony.
Then why did you buy a plus bike in the first place ? Makes no sense
@@deanemberley2333 The PR can be ridden as a 27.5+ or a 29er. I have a 26 and a 29. Not wanting to buy another bike I want to know if the ROAM 30 rim width will fit the Aggressor tires. Question made sense to me. Can you answer it? I might be able to made 29 lb bike weigh 26 lb with a simple wheel change.
Harold Fateley 2.4 WT would be the smallest width I’d go for on a 30mm internal width rim. I don’t think the Agressor comes in a 2.4. 2.5 WT would still work well though compared to a 3 inch plus tire. 2.3 would probably work but it would be pretty flat profile i would think . The new Dissector comes in 2.4. Rolls fast as well maybe another option? Just my two cents
I have a 142 rear low end syncros hub . It use shimano deore 10 sp cassette . Can i change freehub to micro spline and run shimano m7100 groupset ?
Hello, what wheelset do you have? Probably is made by dt swiss and you can buy freehub from dt swiss pawl/ratchet system. Or you can buy sunrace mz90 11-50t cassette with that groupset.
Thank you for repley . Its 2017 spark 760 . Hubs are 142 syncros . Can i change free hub for microspine and use shimano 12 speed ?
@@alifallah1954 watch on your rear hub if has an F on it, i think that bike has formula hubs and you have 5x141 rear hub witch cannot be changed to microspline.
@@alifallah1954 best budget upgrade is 11 speed slx/xt with sunrace mx8 11-46t cassette and you can use your freehub with this combo, and buy narrow wide chainring for your current deore crank. That bike doesnt worth more than that because 12 speed is not cheap right now and shifting is not better.
#askgmbntech hi, I'd like to upgrade my forks, currently using 9mm QR. Most of new forks use bolt through. I still have 2 decent front wheel with QR, is there any conversion kit or method to use them for non boost forks?
aakos26 only ones made for specific hubs. So you have to look up your hub brand to see if they make one. If it’s no name hub your probably out of luck. For a dt Swiss hub set, it’s as simple as swapping end caps.
@@jonathanzappala thank you!
👶
I want the size 31.5
Or 33
Those are the best tire sizes for the DH bikes
Which part of the wheel are the 26", 27.5" and 29" from specifically?
Rim diameter
@@DiegoSteffaloo no mate
#ASKGMBNTECH Hi guys...why Trek uses the 141 Boost system on your bikes? If i need change my wheels...what hub i need buy? Thanks your help. Cheers from Portugal 🤙🇵🇹
Vasco Teixeira that means it is a quick release. They use that on the budget bikes only. You bike should come with wheels why are you buying new ones?
I've got 27.5+ boost. Just bought a mavic deemax elite front wheel which is 27.5 boost but isn't + will it fit?
Hello bro + is the tyre size, boost is hub spacing 110 front and 148 rear. You need boost fork for that wheel.
@@AndreiM1995 cheers mate. I've got boost forks I've just realised my bikes a 29er it was sold as a 27.5 from lbs and I've only just noticed 😅
I was going to buy a bike and change the wheels for a more sturdy pair but now im just not gonna do it...
does anyone know the answer to this? when presented with one rim width measurement, is it internal width or external width. please help!
Internal
Could be either...should say which it is
can a 142mm hub fits a 135mm frame?
Is there no way to put a 148mm hub on a 150mm frame ?
There isn't much if any budget wheels sets out there. I have a bike with the 12x141 qr boost the stock hubs aren't great and the cheapest wheelsets I could find were around $800 Canadian. Why are $1600 bikes equipped with $200 wheelsets that cost a so much to upgrade.
#ASKGMBNTECH can you explain what a top out fork is
And not a single standard of a rear wheel that o ride is mentioned:) I have 24" on bmx 110*14 hub and 26" 135*10 bolt-on hub, not to be confused with QR
Henry!!! @gmbntech #gmbntech
The only thing I should do now is to measure my wheels to know what I do have.
if you have tires on them I would just read the markings on the sidewall
My new Trek uses boost 141 rear spacing ?? What the hell is that ? Another "standard" ??
can i fit 27.5 on a 26 inch frame
Hey, unfortunately no you can’t
how about 12x150
Why does nobody ever talk about the 12x135 rear axle ? ? ?
“Different standards”? Isn’t that contradiction in terms 😂. The bike industry seems to love numerous “standards”
Team 29er!
What do you use
12x142
12x148
12x157
i use 12x142, (IS)
I use 10x135, 12x142 and 12x157
you didn't mention 141 boost???
Guys,what is this rims with skulls ?!
Special edition Mavic Deemax ones.
Is a 650b a 25 inch?
650B is 27.5" 👍
This made me more confused
Hello
#ASKGMBNTECH why my bike cassette and wheel wobble a bit
tighten the cassette bolts or the quick release
Could be many things, put likely worn bearings, axle, loose axle...
@@rupedog I tighten the quick release but when i spin it it wobble
@@seanglysing6913 your wheel might be buckled
I don't think so causes it wobble with the cassette
