if a cx bike could take a 700c wheel with a 40mm tyre on it with no issue, is there any reason why it wouldn’t be ok with a 650b wheel with a 2.1″ tyre on it?
the radius of the 700c/40mm combo is 350mm
the radius of the 650b/2.1″ combo is 342mm
my current setup of 700c/32mm is 344mm
i can’t think why this isn’t going to work……
i just don’t have the spare wheels and tyre combos to test it all, and it’s a rather expensive “experiment”…. thoughts?
(& i realise it’s 4:18 am & i could be talking drivel… i may bump this later in the day)
oh, & the reason i’d want to do this you may ask… erm, not sure yet, i’m sure i could think of something if i thought hard enough about it.
