SRAM Force Mechanical Brake Caliper The SRAM Force Caliper Brake uses identical aluminum forgings as the Red groupo. With a stiffer and more triagnulated upper arm, proper centering and spring tension adjustments are easier. A skeleton-like design and streamlined design call for a lighter and more graceful look where the cable meets the caliper. The Swiss Stop brake pads allow for responsive riding and make it easy to switch brake pads. SRAM employs a dark grey finish and steel hardware to round out the Brake Calipers as a worthy comparison to it's rivals.
