Avid recently debuted the BB7S–a sleeker and slightly (about 7 grams) lighter version of the longstanding BB7 mechanical disc brake. Avid claims a weight of 197 grams per caliper. While it’s been ages since mechanical disc brakes were an apples-to-apples alternative to hydraulic discs in the mountain biking arena, mechanical disc brakes still make sense for cyclocross bikes, commuters and folks with phobias involving hydraulic fluids.
The BB7S features new, stainless-steel hardware, black-anodized caliper, inboard and outboard adjustment knobs and weighs in at 197 grams per caliper. As for rotor sizes, you’re looking at 140- and 160-millimeter HS1 rotor options. The new brake sports organic brakes pads with steel backing plates and carries a price tag of $120.
