Hold your aero position and shift with one fingertip. The Shimano Ultegra ST-R8060-R is the right-hand dual control lever built for time-trial and triathlon cockpits, combining electronic Di2 shifting with rim braking in a single aerodynamic unit that mounts cleanly to TT and triathlon bar extensions.

Highlights

• Electronic Di2 shifting: one-button SD50 port delivers crisp, consistent shifts without cables to stretch or contaminate.
• Aerodynamic profile: slim body designed to sit flush at the end of TT/triathlon bar extensions, reducing cockpit drag.
• Synchronized Shift compatible: connects to the Di2 E-Tube system for automated front/rear coordination with a single button press.
• Reach adjustment: dial in lever position for your hand size and bar setup without swapping parts.
• Firmware upgradeable: update to firmware 3.3.0 or newer for compatibility with current Dura-Ace and Ultegra Di2 groupsets.
• Compact, single-button design: reduced body size versus previous-generation TT levers keeps the cockpit clean and drag to a minimum.

Built for the aero position

Triathlon and time-trial racing demand that you hold your tuck through every gear change. The ST-R8060 puts the shift button right under your fingertips at the end of the bar extensions, so you stay low while the Di2 system fires precisely — no reaching back to the hoods, no breaking position. The aerodynamically profiled body tucks in cleanly and adds minimal frontal area to the cockpit.

Electronic Di2 via E-Tube

Part of the Shimano Ultegra R8050 Di2 family, the ST-R8060-R wires into the Di2 system through a single SD50 port and draws from the BT-DN300 battery via E-Tube. Shimano's Synchronized Shift lets this single lever trigger a coordinated front and rear derailleur sequence, so you spend less mental energy managing the drivetrain and more on pacing. Multi-Shift mode is also available through the E-Tube Project app.

Compatibility & Fit

The ST-R8060-R is the right-hand lever only; the left-hand lever is the ST-R8060-L (sold separately). It is designed for rim brake systems — it is not compatible with hydraulic or mechanical disc brakes. The lever mounts to TT/triathlon bar extensions with a clamp range of 19.0–22.5 mm. It requires a wired Di2 connection; there is no wireless (EW-WU series) port on this lever. In the Australian setup, the right lever operates the front brake. Wiring into the Di2 system requires an E-Tube junction and battery (BT-DN300); confirm your full Di2 system is compatible before purchase.
