If aerodynamics are as important as braking performance, the Shimano Ultegra BR-RS811-R Direct Mount Brake – mounted under the bottom bracket is the optimal choice.
THE SCIENCE OF SPEED: Shimano Ultegra Direct-Mount Brake Caliper BR-RS811-R
Great speed means great responsibility. That’s why, faced with the task of making the new ULTEGRA groupset even faster, Shimano decided to take a holistic and 100% performance-focused approach. Shimano’s new 12-speed road groupset delivers unparalleled control and comfort anytime, anywhere – whether you’re competing in an amateur race, chasing your personal best, or out for a social ride. That is “Science of Speed”. And it’s what sets SHIMANO apart from the rest.
The Dual-pivot or Direct Mount type rim brake calipers bring incredibly powerful performance, offering the best balance between rigidity, weight and stopping power, providing a sleek design, bringing better clearance for tires up to 28C. Direct mount options provide integrated aerodynamic designs at the front (BR-R8110-F) and on the rear seat stay (BR-R8110-RS) or under the bottom bracket (BR-RS811-R).
