True one-finger braking is at your fingertips.

A better finger fit to the hood reduces fatigue on long days, while bonus buttons allow you to change or control ANT+ devices with your thumbs. All this without sacrificing 83 g.

The eTap/AXS SRAM battery is the power source of the eTap/AXS system. The same power unit is interchangeable between front and rear derailleurs. It's time to shift gears. At SRAM , we know that if a technological advancement gets in the way of the experience, it shouldn't be called advancement. Because it's a bicycle. It should be simple. Make something elegant to the point of eliminating what's in the way... It's progress. This is the standard we have adhered to in the development of our first electronic shifting system: SRAM RED® eTap.
