Shimano Ultegra ST-R8020 STI Lever & Calliper

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

• Greater rider control in all conditions
• Hydraulic disc brake provides the next stage of control
• Small bracket size improves ergonomics
• Greater reach adjust range
• Quick and intuitive rear – shifting operation with redesigned internal shifting unit
• Even lighter front shifting when paired with redesigned FD – R8000

Technologies

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 Intergration, 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.

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.

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.
