The front fully bled lever and calliper come without adapters or rotors, giving you the freedom to customise to suit your bike. It can be used with the Center Lock rotor system or conventional 6-bolt rotors in 160 mm, 180 mm, and 203 mm sizes. The opposed 4-piston design reduces leading effect and optimizes pad wear for increased braking control. The two-piece calliper design is both rigid and durable. The hinged clamp design and ergonomic alloy brake lever provide optimum comfort and performance. The Shimano brake fluid is non-corrosive and less hazardous than conventional hydraulic brake fluid. The Shim-less mounting system allows for quick installation and setting up. This kit also contains resin pads, which can be used with sintered and Ice Tech pads.
