Will not fit
- Will not fiterror · ForkFront axle mismatch: Fork is Boost 15x110 but Front wheel hub is 9x100-qr. On 410 of the 490 verified forks in this catalog.
- Will not fiterror · Front RotorFront rotor: a 6-bolt rotor does not mount on a Center Lock front 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.
