650 wheels in a 26" sus fork??

Grannygrinder · Oct 31, 2012

Does anybody know of a modern(ish) suspension fork with enough clearance to run a 650b wheel?
The radius of my 26" front wheel inc tyre is around 335mm, the 650b has a radius of 352mm so only 17mm different.
So any forks about with generous mud clearance??

Actual clearance for the fork will only be affected by half that surely?
And for 17mm difference overall - why bother?

Fox's 650b-specific forks are 17mm taller than the 26in ones -- they're supposed to take a 2.4in 650b tyre. You couldn't run one that big in a 26in fork, a 2.2 or 2.3 may work depending on the exact tyre in question. But 650B and a smaller tyre isn't very much bigger than 26in and a big tyre

...hence my original question :roll:
Admittedly theres not a lot in it, but my relatively low proflie 650b Racing Ralph rubbed on my 2000 SIDS. I'm running 460mm a/c carbon forks for the minute but they state 160mm maximum front disc diametre and i run a 180mm rotor up front.

2002> RS Psylos appear to be the best value option so far

No not half the radius. It will be affected by the whole radius, half the diametre and ***% of the circumference
