Shimano Brake Caliper Ultegra BR-R8100 Rear

The new Shimano Ultegra BR-R8100 dual pivot brakes - Perfect balance between stiffness, light weight and braking performance.

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).

TECHNOLOGIES

• The Dual-Pivot design realized a lightweight, compact and durable braking system. Dual-Pivot Caliper brake have made considerable progress in reduction of tolerance and deflection as well as in durability. They have achieved firm and instantaneous braking response while assuring longer service life. Moreover, the brake pads have an improved durability of 100% to help enjoy high-response braking over longer periods.
• SLR-EV is brand new SLR with dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the new calipers deliver 36% more braking power than SHIMANO’s previous brake model. And we offer 2 axle symmetric brake caliper and fork mount and chain stay mount type.
