Shimano Ultegra R8020 Hydraulic Disc Brake STI Lever - Left

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.

Features:

• 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.
  
• 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.
  
• 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. 8 color options are also available for outer casing to meet many requests.
