Stage I Kit: Cobra MX Floating Rotor & Billet Caliper Adapter
Stage I pairs our Cobra MX 270mm oversized race rotor with a billet aluminum caliper relocation bracket, giving you everything needed to mount the larger rotor on models that require it. It's the same race-proven rotor design used across our AXIS lineup, adapted to semi-floating duty for off-road use, now kitted with the hardware to get it on the bike.
The rotor sports the same pedigree as our established AXIS roadrace full-floaters, using spring washers on the floater buttons rather than ground shims. This keeps it stable in OE floating single-action calipers while still allowing radial expansion under thermal load, in a design that's significantly lighter than a comparable fixed-mount monolithic rotor.
