Electronic shifting removes the cable stretch, housing contamination, and indexing drift that plague mechanical systems. The Force AXS E1 rear derailleur delivers SRAM's wireless shifting at a price point below Red, using the same AXS protocol and battery system while trimming weight from the previous Force AXS generation.

The E1 designation marks SRAM's current electronic architecture, which maintains backward compatibility with existing AXS components while introducing refined internals. Pair this derailleur with Force or Red AXS shifters, and it responds to shift commands in milliseconds with the same crisp actuation regardless of conditions. No cables to route, no housing to replace, no barrel adjusters to fiddle with when temperatures change.

SRAM designed the Force AXS E1 around their XPLR cassette compatibility, meaning this derailleur handles cassettes up to 44 teeth for mixed-terrain riding. The Orbit fluid damper controls chain movement over rough surfaces, reducing chain slap and improving retention without the weight penalty of a traditional clutch mechanism. If you're building a gravel bike or want road gearing that can handle fire roads, this derailleur accommodates that range without compromise.... Read More
