Shimano 105 BR-R7170 rear disc brake caliper, flat mount

The 105 hydraulic caliper for flat mount road frames, supplied for the rear with resin pads fitted. Wider pad clearance means less chance of rotor rub after a wheel change, and the one-way bleed makes servicing straightforward.

  • L03A resin pads supplied
  • Maintenance-friendly bleeding process
  • Average weight 123 g, black finish

Low profile, easy to live with

Shimano's flat mount system keeps the caliper tucked close to the frame for a cleaner look, while the extra pad clearance means wheels go back in without the ticking noise that follows a slightly off-centre rotor.

Compatibility and fit

For road frames with a flat mount rear brake fitting, used with Shimano road hydraulic levers and mineral oil. Supplied as a caliper, without lever, hose, rotor or mount adapter. Rotor size determines which adapter you need. If you are unsure what your frame takes, ask us before you order.

Shimano covers this brake under its standard warranty against defects in materials and workmanship. Normal wear is excluded, which on a hydraulic caliper includes brake pads and seals, along with damage from crash, incorrect bleeding or the use of the wrong fluid. Shimano road hydraulic brakes use mineral oil, never DOT fluid.

Warranty claims and returns go through Tune Cycles. Contact us with your order number and we will assess the part and handle the claim with the distributor on your behalf.
