Shimano Dura-Ace BR-R9270 Front Flat Mount Hydraulic Disc Brake Caliper

The Shimano Dura-Ace BR-R9270 Front Hydraulic Disc Brake Caliper is designed for riders who demand elite performance, reliability, and control in all conditions. Trusted by professionals, this low-profile caliper delivers powerful braking with excellent heat management and easy maintenance.

Built for flat mount forks, it includes an adapter for 140mm and 160mm rotors. The oversized 22mm ceramic pistons offer great heat insulation, reduce fade, and maintain stiffness for precise braking.

The opposed 2-piston design ensures even pad wear, while improved pad-to-rotor clearance reduces rotor rub. The open caliper design makes wheel changes quick and easy—ideal for racing or servicing.

The forged alloy body is lightweight and strong. Shimano’s one-way bleeding system, separate bleed port, and inline hose routing make maintenance simple and your setup clean. Resin pads with aluminium cooling fins reduce surface temperatures by up to 50°C under heavy use.

For best results, use with Ice Tech FREEZA RT-MT900 rotors.
