The Ultegra ST-R8020 Shimano e (ref. ISTR8020RI) is a high-end shift and brake lever designed for road bikes fitted with hydraulic disc brakes and an 11-speed drivetrain.

Designed for the right hand, this lever controls the rear derailleur whilst incorporating hydraulic braking. It features a redesigned ergonomic shape with a more compact body, a better grip and an extended reach adjustment range to suit riders of different sizes.

The gear-shifting system has also been optimised to deliver smoother, more intuitive shifts, even under stress, whilst retaining the precision characteristic of Shimano.
