Precision-engineered Ultegra STI lever with hydraulic disc brakes give you control, modulation and power with minimal effort in all riding conditions.
The Shimano Ultegra R8020 series shifters bring greater rider control in all conditions thanks to Shimano's category-leading hydraulic disc brakes. Lighter front shift action and refined ergonomic shape sweeten the deal.
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 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.
Servowave Action
When you pull a Servowave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
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.
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. 8 color options are also available for outer casing to meet many requests.
Features
- Shift cables are routed under the bar tape: re-development and positioning of the internal mechanism in combination with Polymer coated cables have made this possible, providing faster, lighter and smoother shifting
- Vivid indexing provides a constant amount of shift lever force across all 11 sprockets
- Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes
- Hydraulic brake lever provides excellent stopping power with less effort especially from the hood position
- Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear
- Free stroke adjustment for pad to rotor contact setting
- Tuneable reach adjuster enables custom fitment for all hands
