Avid BB5 MTB Caliper

Proven, reliable, and easy to live with — the Avid BB5 MTB Mechanical Disc Brake Caliper is the benchmark for cable-actuated disc braking on mountain bikes. Delivering consistent, powerful stopping across all conditions without the complexity of a hydraulic system, the BB5 is a trusted choice for trail riders, commuters, and anyone building or upgrading a bike that needs dependable disc brake performance.

The mono-block caliper body is built tough, and the outboard pad adjustment dial makes setting and compensating for pad wear quick and tool-free. The innovative Tri-Align Caliper Positioning System (CPS) takes the frustration out of setup — simply loosen the mounting bolts, squeeze the lever, and retighten for perfect caliper-to-rotor alignment every time. Spring tension is also adjustable, allowing you to fine-tune lever feel to your preference.

Compatible with long cable-pull MTB brake levers. Includes steel-backed organic brake pads. 74mm mounting bolt spacing — mounting adapters and rotor sold separately.
