The Shimano Ultegra ST-R8000 right STI Dual Control Lever combines braking and rear shifting in a single, refined unit built for serious road riders. Designed as part of the Ultegra R8000 groupset, it brings Dura-Ace-derived ergonomics and shift internals to a wider audience — delivering faster, more precise 11-speed rear shifting with a lighter lever action than its predecessor.
Highlights
- STI Dual Control: Integrated shift and brake lever lets you change gears and brake without moving your hands from the hoods.
- Extended reach adjust: Bolt-operated reach adjustment accommodates a wider range of hand sizes, making the lever feel natural for more riders out of the box.
- Revised shift internals: Updated internal mechanism borrowed from MTB technology delivers fast, smooth rear shifts with reduced finger effort — one-finger shifts are achievable.
- Carbon CFRP lever and body: Carbon fibre reinforced plastic construction reduces weight without sacrificing rigidity or feel at the hoods.
- Improved hood texture: Refined surface texture on the hoods provides a more secure, comfortable grip over long rides.
- Rim brake compatible: Pulls compatible Shimano rim brake callipers with confident, well-modulated braking power.
- Polymer-coated shift cable: Included stainless steel, polymer-coated shift cable reduces friction for crisp, consistent rear derailleur actuation.
Ergonomics & Design
The R8000 lever profile is marginally more compact than the previous generation, sitting closer to Dura-Ace proportions. The reach adjust bolt lets you fine-tune lever distance to match your hand size and riding position — reducing reach fatigue on long road or sportive rides. The textured hood surface improves grip and comfort whether you're riding on the hoods or drops.
