Will not fit
- Will not fiterror · ForkFront brake mount: Magura MT8 SL is a post-mount caliper and RockShox Rudy Ultimate XPLR has a flat mount - two different mounting standards, so the caliper does not bolt on as it is. The part that bridges them is a rotor-size-specific flat-mount-to-post-mount adapter. A shim or adapter may make other sizes or standards work, but that is a modification, not a fit. On 2 of the 30 verified forks in this catalog.
