When we're faced with endless rollers, arduous climbs, and victorious descents, we might be asking for more stopping power. Thankfully, that's where the Dura-Ace BR-R9270 Disc Brake Caliper comes into play. This caliper is built to handle tight switchbacks and steep sections with better modulation and enhanced power. And, this design is Shimano's most compact to date. Its Mono-Body construction ensures light weight and rigidity, which goes to show that powerful components can come in small packages. With this design, high-performance braking reaches new heights, and this caliper drops weight while providing increased pad clearance for reduced noise.
