Classic crescent straddle cable carrier for cantilever and center pull brakes.
When Paul Components introduced Moon Unit in the nineties, it was one of the first high quality aftermarket cable carriers.
The Moon Unit has a raised boss for the brake cable clamp that makes setup easy and ensures cable security. Machined channels on the face of the Moon Unit hold the cables in place and an 8mm hex on the back allows you to actually put a wrench on it.
All Moon Units are sold as a pair, with one Unit for each of your brakes, front and rear.
