Will not fit
- Will not fiterror · Front TireWheel size mismatch: Front wheel = 700c, Front tire = 650b. A road or gravel build runs one wheel size end to end. On 30 of the 142 verified tires in this catalog.
- Will not fiterror · Rear TireWheel size mismatch: Front wheel = 700c, Rear tire = 650b. A road or gravel build runs one wheel size end to end. On 30 of the 142 verified tires in this catalog.
- Will not fiterror · Front RotorFront rotor: a 6-bolt rotor does not mount on a Center Lock hub as it is - the two use different rotor interfaces. The part that bridges them is a Center Lock adapter, and the ones makers publish fit one-piece rotors only. A shim or adapter may make other sizes or standards work, but that is a modification, not a fit. On 19 of the 30 verified rotors in this catalog.
- Will not fiterror · Rear WheelWheel size mismatch: Front wheel = 700c, Rear wheel = 650b. A road or gravel build runs one wheel size end to end. On 12 of the 71 verified rear wheels in this catalog.
