For the first time, NEW Shimano Dura Ace Brake Caliper employs a front and rear specific system that is more powerful and lighter than the original Dual Pivot design.

The compact construction of Dual-Pivot increases leverage and power, while reducing weight and size of caliper arms. An overall front/rear weight reduction has been achieved, while boosting rigidity in the front caliper by 25%.

Increased rigidity, tighter tolerances and the striking reduction in flex are a big part of the BR-7800 story, but the new multi-condition brake pad compound has also made race-winning advancements. In development for over a year, the new pads are more powerful and durable in dry conditions, with outstanding durability in the wet as well. The powerful braking and endurance in the wet, with no compromise to the power and durability you need in the dry, has been recognized as a significant racing advantage.
