Technology

New Super SLR

SLR stands for Shimano Linear Response. The New Super SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation.

Also for the lever, the Servowave mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control.

SLR is the essential factor in the Shimano dual-pivot caliper that deliver more braking power than conventional side-pulls.

Dual Control Lever

DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation.

Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from our MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.

The Dura-Ace / Ultegra / 105 Dual Control Lever have an optimized structure with features that include the lighter weight pivot section in the near side of the shifting unit and the integral shifting cable for lighter steering. Its many component parts are made so compact and precise to achieve unprecedented high-speed performance.

Optislick

Optislick cables feature a minimal and uniform electrically coated layer that improves cable routing efficiency and provides excellent corrosion resistance.

Reach Adjust

Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.

OT-SP41

With OT-SP41 the entire length of the outer casing is pre-lubricated with a special silicone grease for quick and precise shifting performance. OT-SP41 maximally reduces the inner cable friction to provide quick response to operations and easy/effortless shifting. 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.
