Will not fit
- Will not fiterror · FrameRear axle mismatch: Frame is Boost 148x12 but Rear wheel hub is 142x12. On 228 of the 258 verified frames in this catalog. Applies to 1 of 3 variants.
- Will not fiterror · Rear RotorRear rotor: a 6-bolt rotor does not mount on a Center Lock rear 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 112 of the 177 verified rotors in this catalog. Applies to all 3 variants.
