The Shimano 105 BR-5810-RS Brake Caliper Rear Seatstay Direct Mount is proof positive in Shimano's "trickle down" effect from their renowned Dura-Ace and Ultegra components. By attaching the brake caliper directly to the frame's seatstays, instead of the conventional bolt through the brake bridge design that road bikes have utilized for ages, Shimano has reduced redundant parts and increased the brake's performance. Furthermore, this integrated brake design improves aerodynamics. Direct mount design reduces redundant parts and increases overall braking performance Integrated design with aerodynamic profile Rear brake only Weight: 175g
