Features1Heat Dissipation: The double row hollow heat sink is integrated with the brake pads to quickly conduct and cool the high heat generated by the brakes, avoiding the failure of high temperature oil pressure lock and long term brakes. 2Polygonal Airflow Dics: Floating dics adopts polygonal airflow design, which has good heat dissipation performance and the large hole spacing is not easy to accumulate sand and dust. 3Three Finger Brake Lever: The three finger brake lever is easier to master and control, and the dual piston design makes the braking performance stronger and more reliable. 4Applicable Model: Made of aluminum alloy material, compact, lightweight, sturdy and durable, used in the braking system of ordinary bicycles, mountain bicycles and road bicycles. 5Frosted Brake Lever: The frosted surface of the brake lever has concave holes to increase friction and reject hand slippage caused by hand sweat. Features are sensitive and strong braking, good stability, good hand feeling.SpecificationProduct Name: Wire controlled hydraulic disc brakeMaterial: Aluminum AlloyColor: As Pictures ShownWeight: Approx. 500g/17.6ozFront Disc Brake Cable Length: Approx. 0.8m/2.6ftBrake Lever Length: Approx. 83mm/3.3inBrake Lever is Suitable for 22.2mm/0.9in HandlebarsDisc Diameter: Approx.160mm/6.3in BCD: Approx. 44mm/0.16in (Hole to Hole)Package List1 x Front Brake8 x Screw1 x Disc
