Shimano's 12-speed R9200 Dura-Ace series delivers top-of-the-line technology for smooth operation and a fast drivetrain. In particular, the Dura-Ace BR-9200 Brake Caliper stands out as one that delivers consistent power distribution and reliability for the best on-bike experience possible. And, when it comes down to it, that's what Shimano strives to provide for us. Shimano builds this caliper with their SLR-EV dual symmetric pivot design, which reduces flex for improved braking modulation, and an efficient design that balances rigidity and weight with stopping power. It clears tires up to 28mm, which is ideal for cruising tarmac comfortably, and delivers predictability and power for rides where we feel unstoppable.
