The experiment angle I was referring to was the unbraced Quadangle Gamble. Not 650B+. The latter makes sense, the former does not (especially in combination with + float/cush).
loving that monster anotherstan!
where i live massive tyres just make sense, up to a point anyway. i can only fit 2.4s in my frame, but i’d love say 3″. don’t need to ride any tarmac and a lot of it is rough and rooty as anyhing.
