Precision-engineered Ultegra STI levers with carbon levers offer powerful braking & effortless 11-speed shifting, making them the ideal choice for both enthusiast & competitive riders. Shift cables are routed under the bar tape: re-development & positioning of the internal mechanism in combination with Polymer coated cables have made this possible, providing faster, lighter & smoother shifting. Vivid indexing provides a constant amount of shift lever force across all 11 sprockets. Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid & precise gear changes. Powerful & controllable braking thanks to SLR-EV compatibility. Tuneable reach adjusters enable custom fitment for all hands.
