In the world of freeride and DH, you need complete and utter faith in your brakes. You need serious stopping power with feathery modulation. So whether you're scrubbing mach 5 speeds or slowly picking your way down techy gnar, Shimano's ZEE Disc brakes have your back. This post-mount caliper is equipped with four oversize ceramic pistons for fade-free, shudder-free, and noise-free braking. One-way bleeding makes maintenance a snap, and the calipers are compatible with Shimano's ICE-Tech brake pads (sold separately).
