The Ultegra BR-6810 Rennradabremse works on the Dual Pivot principle, the so-called double-jointed system, built by Shimano for a long time and now work almost all Road_Brake according to this principle. The advantage of this system is the synchronized movement of the brake arms and thus a uniform pressure build-up on both sides of the rim flange.
The Ultegra brakes are still equipped with the Super-SLR System (Super Linear Response) for reduced friction, better control and thus a more direct brake response. In connection with the new polymer coated brake cables BR-R680, a further improved modulation and controllability is achieved.
The handling has been further improved since the Bremszugeinsteller, the quick release for easy wheel changes, an adjustable angle of the brake pads and a return spring with adjustable tension would.
The brakes are equipped with brake shoes R55C4 with new paving mix for aluminum rims.
The Ultegra BR-6810 road bike brake for Aero Bikes is available in three different mounting options, for direct mounting on the fork (BR-6810-F), for direct mounting on the chain stay (BR-6810-R) and for direct mounting to the back the seat stay (BR-6810-RS).
