I am looking at getting new forks but want to 'future-proof' - can I run my current 26" wheels in a 650b fork until they break then get 650b wheels? I know it will affect the height/head angle very slightly but I don't see a reason why it won't work.......
Cheers!
Surely the only difference (other than marketing 😆 ) is the arch will be a tad higher - running 26" in 650B will just mean you get awesome mud clearance height wise
it'll be fine.
There was a picture somewhere of a YETI I think ? That was a 650b but had 26" wheels on it, I thought it looked quite good ?
I had a crosser when I was younger RM 125 with wheels off an RM 80 it reminded me of that so that's the recconing behind my theory?
Do it, and then upgrade the wheels at a later date if it does eventually take off,
You're looking at gaining maybe 15mm of axle-crown height, so a sagged 120mm 650b fork will give you the same geometry as a sagged 140mm 26" fork. And a ton of mud clearance!
Cheers, kind of what I thought 😀
The only thing that might cause bother- usually the arch flares out around the tyre, so with the tyre sitting slightly further "in" you might lose some clearance. But the odds of that being a problem seem slim
Put a big 2.4 tyre in to fill any of the gap?
tbh My 26" 140mm fork has died and I've been considering options like this too.
My X-Fusion Vengeance are for 26" wheels but can also accept 650b - apparently
if it's a true 650b fork it will have increased offset so might be a little twitchy with the smaller wheel.
as said, the x-fusion forks cater for both but I'm not sure if they are inbetweener offset-wise or just sitting on the old 26" offset and making do.
It will slacken the bike abit so more fun
