Feature: Aluminum alloy products are forged from aluminum alloy materials to increase durability and strength, reduce weight and burden, and make riding more comfortable and safer. The four-piston drive uses four pistons on both sides to the disc, which improves the braking for force, makes the braking smooth, the disc does not deform, and the safety factor is high. Integrated oil cylinder oil cylinder design, strong sealing, avoid brake lever oil leakage and air intake, lightweight design, beautiful and practical. Brake lever adjustment adjusts the distance between the brake lever and the bicycle according to your own needs to make riding more comfortable. Ergonomically designed handle with a length of 102mm and anti-slip particle design makes it comfortable to hold and prevents your hand from falling off. It is not crowded when you put down three fingers. The brake is light and effortless, and is in line with ergonomic design Specification: Product name: Four-piston oil disc Material: aluminum alloy Colour: Black Dimensions: as shown in the picture Weight: about 710g(pair) Size: front/rear split Oil pipe length: front 850mm/rear 1600mm Installation dimensions: standard A-pillar 75mm/standard B-pillar 51mm Package Content： Four-piston oil dish* set(the goods you receive for depend on the attributes of your order)
