SRAM Force AXS E1 2X Groupset
SRAM Force AXS E1 2X Groupset Info
The SRAM Force AXS E1 2X Groupset is the current generation of SRAM's pro-level road drivetrain — fully wireless, 12-speed, and meaningfully refined over the groupset it replaces. The E1 update sheds 183 grams from the previous generation Force AXS while adding improved brake ergonomics, faster front shifting, and increased drivetrain efficiency. For riders who want the performance of a top-tier electronic groupset without stepping up to RED pricing, Force AXS E1 is the clear choice.
This groupset bundle includes the front and rear derailleurs, Force AXS shift/brake levers, two flat mount hydraulic disc brake calipers with rotors, a Road Flattop E1 chain, and batteries with chargers — everything needed to build up a complete wireless drivetrain except the crankset and cassette. The brake levers have been redesigned with a new hood profile that enables one-finger braking from any position on the bar, reducing hand fatigue on long descents or technical terrain. The front derailleur runs quieter than any previous Force generation, with a slimmer cage and auto-trim that eliminates the need for manual trim adjustments mid-ride.
The rear derailleur covers cassette ranges from 10-28T up to 10-36T, making this groupset adaptable across different climbing demands without needing to swap components. Larger X-SYNC pulley wheels improve chain wrap efficiency, and SRAM's chain management technology keeps the drivetrain quiet and secure on rough road surfaces. The AXS app connects wirelessly to customize shift logic, monitor battery levels across all components, and update firmware — the system surfaces information that would otherwise require a trip to the workbench.
