I think you can squeeze 38mm with guards on 650b. Genesis say 32mm is max without guards but I'd be interested to see if you get the 35mms on.
I'm currently running 28mm with guards and there's tons of room in the fork and not much in the rear (on the newer thru axle model)
*Edit - Looking back through old emails they told me 30c is the max, that's obviously not right.
maybe they were assuming knobbly tyres and gave a "secure" answer.
Yea definitely going for the conservative response.
Seems bonkers they'd change the rear design and not allow for bigger tires given current trends and all.
