New Lever Design Enhances Control for Aspiring Cyclists. The Shimano CUES U6030 Dual Control Lever inherits advanced features from our renowned Shimano 105 series. Its updated lever position and bracket designs were developed through extensive research on different hand shapes. Budding road and gravel riders will feel at ease thanks to this refined lever design, the reliable performance of hydraulic disc brakes, and the smooth, intuitive shifting that Shimano CUES is known for.
Technology
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 optimised 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.
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.
Features
- Refined lever shape shortens the reach distance, allowing riders with a wider range of hand sizes to comfortably access the lever
- LinkGlide technology is very durable, up to 300% more durable than current Hyperglide drivetrain and maintaining smooth shifting
- Ergonomic short shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes
- Hydraulic disc brake dual control lever pivots have been positioned to increase power and improve ergonomics when riding on the hoods
- Tuneable reach adjusters enable custom fitment for all hands
- Comes complete with Optislick coated cables and silicon greased outer casing to further reduce shift friction and increase service life
