Shimano Dura-Ace Rear Seat Stay Brake (Direct Mount)

If your bike boasts mounts for direct-mount brakes, you've got a savvy builder. These brakes trim weight, enhance clearance, and sometimes boost aerodynamics. Shimano offers three Dura-Ace 9100 versions: one for the fork (BR-9110-F, 155g), one for the seat stays (BR-9110RS, 152g), and one for under the bottom bracket (BR9110-R, 133g), each sold separately. They all employ the dual-pivot concept, refined here from the 9000 series. More than just a fresh finish, the arms are reshaped and lengthened to accommodate fatter tires, with room for 28mm tires. A stabilizer between pivots stiffens the arms, reducing flex for more predictable braking. Sleeker arm shapes on F and RS versions save space and improve appearance. A micro-adjuster and barrel-adjuster ensure easy adjustments. The centering bolt and standard aluminum rim-specific brake pads are easily accessible. The Shimano Dura-Ace BR-9110 Direct Mount Brake delivers lighter, stiffer braking via specific frame mounts.
