Offering an 11mm lower profile for improved aerodynamics while still allowing clearance for up to 28mm wide tyres, the rear Shimano Dura-Ace R9210-RS Seatstay Direct Mount Rim Brake grants performance to dedicated racing cyclists. The design includes enhanced brake arch proportions for a quicker linear response and increased power, while the thrust bearings and coated bushings provide a smooth and progressive feel. Moreover, precise set-up is possible thanks to the spring tension adjuster and easy toeing-in of the brake pads, allowing the braking sensation to be finely tuned.
