Shimano Ultegra BR 6800 Brake Caliper. Want some Dura Ace brake action without a Dura Ace price Using Dura Ace's pro level technology with a very slight weight sacrifice, Shimano's Ultegra BR 6800 brakes use a symmetrical dual pivot design so that each arm travels the same amount when the lever is squeezed. Couple the resulting efficiency and superior modulation with Shimano's exclusive new pad compound, and the result is a powerful brake that won't grab, won't overslow at critical race moments, and will stop when you say stop.
