That rear axle looks too narrow and weedy.
cynic-al » Also…B+ narrower than 29+, what’s the point?
I might have this wrong but there seems to be some sort of challenge in getting a 3″ tyre on a wide rim to work with a 73mm BB. This works for 29+ though, so I can only assume it’s something to do with shorter chainstays creating a strange angle?
It pains me to say it but, if that’s the case, then a wider BB, wider rear axle should help.
Is B+ not supposed to fit in many normal 29ers and existing fatbikes? Which is kind of uncharacteristic for this sort of thing, it’s supposed to require a new bike…
29ers? Dependent on chainstay width. Fatbikes – should fit in them all but many folk seem to think that a 100mm BB is going to host of knee problems.
