Shimano Dura-Ace ST-R9270 Hydraulic Di2 Brake Caliper

Shimano has designed the BR-R9270 flat-mount brake caliper for the Dura-Ace top road groupset in a one-piece Mono-Body construction. Compared to the Ultegra version, this saves over 20 grams of weight at the rear and front and increases the stiffness even more. The brake pads have more free space than in the previous model, which prevents grinding of the brake rotor and reduces noise. The braking power of the two plastic pistons is tuned for competition use. In addition, the BR-R9270 earns points with a simple bleed process thanks to One-Way Bleeding technology. The brake caliper is supplied with Ice-Tech resin pads, which ensure particularly good heat dissipation due to their cooling fins. However, you can also ride it with conventional pads.
