For years now, ball bearing, cable actuated mechanical disc brakes have been a favorite among riders who want control, durability, dependability and piece-of-cake adjusting. The adjustment knobs on the BB7 make quick work out of setting the perfect distance between the pads and rotor, as well as adjusting for pad wear. This is something you just can't do with hydraulic brakes. After all, not everyone is an expert mechanic with the time to bleed and maintain hydraulic brakes especially if you are in the backwoods when they fail.
The Avid BB7 Mountain Mechanical Disc Brake Caliper with G2 Rotor is designed to be used a linear pull, V-brake style mountain lever. Cable actuation makes them easy to set up, reliable, and they deliver plenty of nicely modulated braking power that blows away non disc brakes.
Avid's Tri-Align Caliper Positioning System lets the caliper align to the rotor and literally takes seconds. Just loosen the CPS bolts a little, and then squeeze the brake lever while re-tightening the bolts for a perfect alignment. Inboard and outboard Speed Dial Pad knobs allow for quick, precise and easy brake pad adjustments as the pads wear. Spring tension is also completely adjustable.
The BB7 Caliper installs to a 74mm mount and a adapter is included for a 51mm international standard mount. The Included G2 clean sweep rotor fits 6-hole hubs. Works for front or rear, cable and lever not included. Order two sets for one bike.
