I’ve got 26 in the front and 29 in the back.
Awesome, it rides like a dragster.
I’ve also attached a empty plastic bottle between the frame rubbing the back wheel for a really cool motorbike sound.
26 all the way……
I have a bike on 27.5 wheels if you ride on asphalt be carefull when you turn because if you go fast like i do sometime the tire stretch and is almost expulsed from the wheel . Its a VERY scary feeling when it happen on the front wheel .be ready to have ALOT of rebound ,imo regular tire are by far better .
26 for life!
wtf is he saying
1:05, they are 250 gr different
Wait o dont get it
Any 29 front 27.5 rear wheel riders?
wouldnt it have made sense to use the same tire?
Just dreaming about having one of those bikes that you use in your videos.
does anyone ever go 29 on the front and 27.5 on the back?
I ride 27 X 1 14 on an old aluminium MTB frame with no front or rear suspension. As a high-mileage – old fart – cyclotourist the combination works great for me and on the flat can easily keep up with 29ers and wave a friendly bye bye to anyone on 26ers. I don`t race but find my wheel and tyre combination is great for dirt roads and yes it digs into sand but even on a bike with fatter tyres I go slowish downhill on sandy roads after flying over the handlebars once when I ploughed into a deeper than expected sandy spot and the front suspension bottomed out creating a rotation and VTO.
My XC bike is a 29er and my trail bike is 27.5. XC bike is a hard tail. Trail bike is full squish. And I have got to admit that I wouldn’t have it any other way atm. The next trail bike might get bigger wheels and my next XC bike will probably have a short travel rear shock but as we are all aware I am recovering from a serious, nearly life changing, injury and having the 2 very different bikes has helped loads because one is all about the pedalling and the other is all about moving around on it.
Some folks will pay more just to get the tire in their bum I suspect… :-]
At my age of 56 I can accelerate better on my 26 than my 29. Havent tried a 27.5 yet.
Love them both depending on the type of ride I’m doing. Having 2 pairs is smart!😉
27.5 inch wheels are better than 29 inch wheel.
Have you tested a 27.5 in the back, and a 29 in the front?
I don’t think there’s much difference between the wheels but my girlfriend reckons inch and half bigger makes all the difference. I’ve never even seen her ride a bike so dunno how she formed that opinion.
Seems to me a 27.5 wheel will stay truer for much longer. LESS LEVERAGE.
What about 26in?
You should have wore a full face helmet. That bike helmet wouldn’t have helped a lot if you smash into a tree at 25mph.
Yo I have a 26 ….
Dont kick me
When you flipped the chip I would think it was in the low setting, so you are flipping it to the hi setting. Why would you want to do that with the B.B. already going up with the bigger wheels?
It’s a sales tactic…all my Bros who ride 27.5 cant keep up to me on my 26" wheels, light, strong and definitely not buying into this bike industry bullshit! I have over 10 -26" rigs , I’ve invested a lot of skrilla and I wont be upgrading anytime! Keep em, thanks for showing us that they are not worth it.
BB drop or offset as you called it is a straight line from axle to axle then measured how far below that line the centre of the bb is. You haven’t changed the position of the axles so your bb drop/offset is exactly the same no matter what size your wheels are. Do you mean clearance?
No need for a war, just be creative:
27.5 at front and 29 at the rear. Problems and discussion solved 🙂
PS: i am owning a 27.5 bike and 26 bike. Tried a 29, but that felt horrible to me. i’m just 5 feet 9, so that’s prolly the reason 😉
250g not 25
Where do you buy that bike?
Two years ago the debate was ’26vs27,5′. Soon we will be sending on penny farthings😂
Kaiser vs Baron – not exactly same tires…
ok so i have had a 22 inch cube fore many years as got it off a friend years ago and i am only 5ft 10. so going by there website i should be on a 18" 19" at a push. with inside leg length. I fell in love with a second hand cube attention 2018 …….. it is a 19" now after comparing that to my old bike at 22" i knew it was a lot smaller 3" in fact. I looked up the 19" and they have 29" wheels. i did not think much of it and got the bike met the person half way between and got it. My question is as although the frame is 19" the 29" wheels add more to the size as my 22" was only 27.5. I feel like there is not that much between them. I have got the 19" and i ma enjoying ridding it. Is there really much difference between a 18" 27.5" vs 19" 29". i am the same height as you. I will use it a lot on roads and trails so a bigger frame is ok. just for years i wanted to get an 18" thats perfect size for me. But i love the bike so much i couldn’t let it go aha. Is there much difference to worry about thanks
26 all the way. 27.5, fine. 29= ridonculous unless you’re 6’4" and into xc
What are you thoughts on running a 29er up front, and a 27.5 on the rear (or vice versa?)
which would be better for the hill climb 29 or 27.5 ?
Pick a wheel size and be a dick about it. 👌
Great production value.
Damn what a beauty
my aero racebike would be faster there with its continental 5000 tl
1:07 the weight difference is 250 grams. Not 25 grams.
Two wheel total is 500 grams, which is half a kilo, not 50 grams.
I ride 27.5 and I’ll never be tall enough nor have enough confidence to ride a 29
What will be next dimension, 28.25?
im thinking of getting a new mountain bike and I’ve just turned 14 and im about 6,1 should i get 29 inch wheels or smaller??
My penis is 29" long using a special homemade ruler.
1:09 That’s 250 grams difference, both wheels are 500 grams of difference
To be able to use the same fork with both wheels, did you start off with a frame set up for a 29? I’ve heard that a person can use 27.5 on a bike setup fir a 29, but generally not use 29s on a bike setup fir 27.5. I understand the fork is the limiter.
If buying a new bike, and one wants to possibly interchange between wheel options, which size (27.5 or 29) generally would you go?
29 !) 👍
Wht is the bake called
26 giles ql
