Shimano delivers their trademark smoothness and ergonomics with the 11-speed Ultegra shift levers.

Hand-pleasing ergonomics offer near perfect hood and lever placement so these controls are comfortable all day long, whether you're cruising on the tops or deep in the drops.

On top of all that, stealthy, under-the-tape cable routing cleans up the front of your bike, with a clean, minimalist, and pro look.
