The New Super Shimano Linear Response design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation. The brake lever is equipped with a reach adjust mechanism which means that the distance from the handlebar to the lever can be adjusted to suit any hand size, type of riding or preferences. The Dual Control Lever has brake and shifting functions in the system and enables easy operation. Furthermore, the ergonomic innovation borrows the robustness from the MTB technology and is so smooth and effortless that one finger can shift. With OT-SP41 the entire length of the outer casing is pre-lubricated with a special silicone grease for quick and precise shifting performance. Moreover, power loss due to delay in shifting and fatigue by shifting especially when you ride on the terrain with many ups and downs as well as a long distance is also reduced.
