Firm, instantaneous and powerful, Shimano's Dura-Ace Brake Calipers set the standard in braking. These class-leading brakes may be the most powerful road stoppers you've ever used. They're made of lightweight cold-forged aluminum and sport a redesigned caliper arch that creates better lines for the cables to reduce friction. This gives you predictable modulation with amazing braking power: wet, dry, it doesn't matter. True to D-A tradition, you get the easy-to-replace cartridge brake pads, and easily adjusted spring tension and centering screws.
