Aero bar extensions put your shifters out of reach, which is a problem when you're in the tuck and need to change gears. SRAM's Clic Bar End Shift Buttons solve this by adding dedicated shift controls at your fingertips, connecting wirelessly to your Red eTap AXS derailleur system. The buttons mount inside standard bar end plugs on clip-on or integrated aero bars, giving you the same shift-anywhere capability that defines eTap without removing your hands from the aerodynamic position.

The system runs on a single CR2032 battery per button that SRAM rates for approximately two years of use. That's roughly the same battery life as standard eTap shifters, and replacement batteries are available at any pharmacy or electronics store. Each button connects to your existing eTap system through SRAM's AXS app, which handles the pairing process and lets you assign shift functions. You can configure them as left/right matching your hood shifters, or set both to the same derailleur if you prefer redundancy on a single unit.

Installation requires drilling a small hole in your bar end plugs for the shift button to protrude through. The buttons themselves have a low-profile design that sits nearly flush with the bar end surface. Rubber seals around the button mechanism provide weather protection, which matters when you're face-first in the elements during a time trial or triathlon.... Read More
