The Shimano Ultegra BR-R8000 rim brake set captivates with an elegant, narrow design, which provides at the same time for more tyre clearance. This means that tyres up to 28 mm wide can be used without any problems. The 51 mm long brake arms are equipped with a stabilizer bar that counteracts deformation. Thanks to a revised dual pivot design and SLR-EV technology, superior braking power with optimum controllability is a matter of course. BR-R8000 comes with adjustable cartridge brake shoes, quick releases, tyre protectors and brake pads for aluminium rims.

Dual Pivot
Dual pivot technology results in weight-saving, compact and robust brakes. In particular, the brakes from Dura Ace, Ultegra, 105 and Sora now offer maximum torsional stiffness and maximum load capacity with minimum tolerances. They respond precisely and without delay and their service life is significantly longer. In addition, Dura Ace, Ultegra and 105 brake pads are 100% more durable, allowing the rider to maintain the high performance of the brakes for longer.

SLR-EV is a revised SLR with symmetric dual pivot side-pull brakes. A short-arm brake design uses two bearings and a roller to achieve greater efficiency in the joint area and provide superior modulation and force when braking.
