Asking for a friend, but can the Rollr take a 650b tyre/650 shod bike? Or, is the limitation bike size and too low a front end can then become a problem?
There are reviews online that suggest 650b is fine, others that say not and the device webpage makes no mention other than that mountain bikes or CX might not fit due to the geometry.
Core of the question being. If a bike definitely fits on 700c wheels, will it definitely fit on 650b, maybe fit, or definitely not fit?
Thanks
