Thanks! Actually long 700cx60 but reradiused for 650b making them 67mm wide. Those are 2,2” Conti Racekings, but I have also used Schwalbe Ice Spiker Pro 2,25” in winter.
Likely doable, I think GB recommends max 2,3” for 60mm, as the profile is relatively flat compared to 50mm. Fitting anything wider than 40mm, particularly something with knobs or spikes was challenging.
