Shimano IBRR8070F1RF Ultegra Flat Mount Front Disc Brake Caliper, Gray

•  Shimano uses the minimal and lightweight Flat Mount design that helps it integrate smoothly on a fork blade or chainstay reducing any aero detriments.
•  Calipers come with finned brake pads to better dissipate heat and when paired with SM-RT800 rotors, the system offers excellent heat management capabilities surpassing that of the already excellent ICE TECH Freeza rotors for consistent performance and no heat-related fade even on the longest descents.
• They are winning big races now too. The hydraulic Ultegra BR-R8070 provides tons more modulation and power than you could ever hope for from a rim brake setup and that helps provide confidence on any descent
