Take your brakes to the next level by upgrading to Origin-8's Pro-Force Light Cartridge brake shoes. They feature ultra-light aluminum skeleton-style holders with Origin-8 Pro-Force Light cartridge brake pads. These fine pads boast a 4-function surface for superior braking performance in all conditions. The front of the pads plows through contaminates on the rim, while the second section "primes" the rim surface and removes any moisture on wet days. Then, the large third section is centered on the bolt axis for uniform pressure and grip, and the fourth section is an anti-squeak compound that eliminates noise and the need to "toe-in" the pads.
