At SRAM, they know that if a technological advancement clutters the experience it shouldn’t be called an advancement. Because it’s a bicycle. It’s supposed to be simple. To make something elegant to the point where it removes what’s in the way... that’s advancement. That's the standard SRAM held themselves to while developing their first electronic shifting system; SRAM RED® eTap.
SRAM RED® eTap features race-car-inspired paddle shift logic that virtually eliminates mistaking upshifts for downshifts, while keeping shifting precise, fast, and easy. It’s a logic that is simplified for speed: right lever makes it harder, left lever makes it easier, both levers to change the front ring. Revised ErgoFit™ controls seamlessly connect rider and machine with Reach Adjust™ to fit any hand. You’ll shift more, with less effort and spend less time doing it. Carbon ErgoBlade™ levers and large SRAM eTap paddles provide positive controls for rider input.
The SRAM RED® eTap rear derailleur executes shifts the instant you demand it, with military precision. Wirelessly. It’s easy to set up, clean in appearance and delightfully uncomplicated. Mechanical necessities such as a carbon pulley cage, ceramic pulley bearings, and anodized alloy artfully blend with proprietary electronic advancements to deliver a 238g (with battery) shifting wonder.
SRAM Yaw™ technology changed front shifting forever, eliminating the need for trim. The SRAM RED® eTap Front Derailleur makes a good thing better by executing front shifts confidently and quickly over their proprietary wireless communication protocol. The eTap shifter optimizes Yaw adjustments as needed throughout the shift range with no need for rider input.
SRAM eTap Battery is the power source for the eTap system. The same power unit is interchangeable between front and rear derailleurs.
eTap batteries are literally a snap to remove and charge. Just flip the tool-free battery latch up and slide the battery up and out of the derailleur. Then snap the battery into the USB powered charger and connect the charger to any USB power source or A/C USB adaptor.
