The Shimano ST-R8060-R is a right-hand bar end shifter and mechanical brake lever combination designed specifically for time trial and triathlon bikes. It is part of the Ultegra R8050 Di2 series and allows riders to shift gears electronically while controlling rim brakes from an aerodynamic position. The lever features an aerodynamic design to reduce drag, a single-button layout for intuitive shifting (compatible with Shimano Synchro Shift).

Installation is straightforward—suitable for handlebar ends with an inner diameter between 19 and 22.5 mm. The shifter is best for cyclists who want reliable, precise electronic shifting and mechanical brake control on rim-brake TT/Tri setups without the bulk of conventional shifters. Unlike previous models, it eliminates the separate switch box for a smaller, sleeker profile, and is compatible with Shimano’s E-Tube platform for customization. The shifter is matched to 11-speed rear gearing and works with Shimano Di2 systems.
