SRAM Force AXS E1 Rear Derailleur Info
The SRAM Force AXS E1 Rear Derailleur brings wireless shifting to riders who don't want to compromise on performance — just the price of entry into the Red tier. It runs fully within the AXS ecosystem, handling both 1x and 2x configurations and supporting cassettes from 10-28T up to 10-36T, which means it's equally at home in a criterium build as it is on a bike geared for long days in the mountains.
The E1 revision isn't a cosmetic update. The redesigned cage sheds 12 grams over the previous generation, and the larger X-SYNC pulley wheels are designed to improve chain retention and drivetrain efficiency across the cassette range. Setup and customization happen through the AXS app — pair the derailleur, adjust shift behavior, and push firmware updates from your phone, with no cable tension or barrel adjusters to manage once you're up and running.
