The complete SRAM Force AXS 2X E2 groupset embodies the excellence of wireless electronic shifting for road cycling, with pro-level performance at a more accessible price than Red AXS. This E2 version with USB-C charger integrates all the major improvements from Red AXS: redesigned lever ergonomics, increased braking power, even faster and quieter shifting, all with a weight saving of 183 grams compared to the previous Force AXS D2 generation. Complete and ready to install, this aftermarket kit includes rear derailleur, front derailleur, hydraulic shift/brake levers, two AXS batteries, USB-C charger, Force Flattop 114-link chain, flat-mount brake calipers and Paceline 160mm rotors — you only need to add crankset and cassette to build a fully performing 2x12-speed drivetrain.

Technical overview of the Force AXS E2 system

The Force AXS E2 groupset uses SRAM's proprietary AXS wireless architecture, proven on Red and Eagle, guaranteeing instant and reliable gear changes in all weather conditions. The rear derailleur covers cassettes from 10-28T to 10-36T (XDR 12-speed), offering remarkable versatility from flat-lander to climber, without changing components. The front derailleur uses Yaw technology with electronic auto-trim: the cage pivots and adjusts automatically according to your position on the cassette, eliminating any chain rub and any need for manual trim. The AXS batteries recharge in 60 minutes via the included USB-C charger (cable not included), offer approximately 60 hours of battery life and are interchangeable across the entire SRAM AXS ecosystem (road, gravel, MTB).

Ergonomics and braking: the major improvements of the E generation

• New Force AXS E2 levers: thinner and more ergonomic hoods, adapted to a greater diversity of hand sizes; tactile textures to instantly locate the integrated bonus buttons; adjustable reach for personalized comfort.
• Optimized hydraulic braking: stiffer calipers, push-rod architecture inspired by Red AXS, enabling precise one-finger braking from the hoods as well as from the drops, with improved modulation and consistent power in wet or dry conditions.
• Programmable bonus buttons: each lever has additional controls on the inside of the hoods, configurable via the AXS app to control a GPS computer, connected lights, or any AXS function (page shift, lap, sequential mode…).
• Simplified eTap logic: right button to shift harder, left to shift easier, both simultaneously for the front derailleur — intuitive, immediate, no learning curve.

Wireless 2x12-speed drivetrain: precision and versatility

• Force AXS 36T rear derailleur: a single derailleur covers all 12-speed road cassette ranges (10-28T, 10-30T, 10-33T, 10-36T), compatible 1x or 2x; redesigned cage is lighter (12 g less vs previous generation), enlarged X-SYNC pulleys for better chain efficiency, Orbit Fluid damper for smooth and quiet shifting on all terrains.
• Force AXS Yaw front derailleur: narrower cage than before, reducing shift travel and speeding up chainring changes, especially to the big ring under heavy load; permanent electronic auto-trim guaranteeing total silence across all gear combinations; included adjustment tool for quick and precise setup.
• Force Flattop 114-link chain: HollowPin flat link optimized for efficiency, longevity and quiet operation; compatible only with 12-speed road and 13-speed XPLR AXS drivetrains (not compatible with Eagle).
• Compatible chainrings (not included): standard 2x configurations 46/33T, 48/35T or 50/37T (8-bolt direct mount); 2x Wide configuration 43/30T (94mm BCD, requires specific Wide front derailleur); 1x options from 36T to 46T also available for gravel/all-road use.
• Compatible cassettes (not included): Force XG-1270 or Red XG-1290 in 10-28T, 10-30T, 10-33T, 10-36T (XDR freehub body required); one-tooth progression for fine gear ratio adjustment.

AXS connectivity and advanced customization

The SRAM AXS app (iOS/Android) allows you to fully customize the behavior of your groupset: button inversion, automatic sequential mode (the front derailleur shifts automatically to maintain linear progression), bonus button programming, battery charge status monitoring (remaining time, history), maintenance reminders, OTA firmware updates. ANT+ connectivity also ensures integration with compatible GPS computers (chainring/gear display, direct control from GPS). No cables, no housing: clean installation, reduced maintenance, maximum reliability.

Weight, materials and finish

The Force AXS E2 groupset in 2x configuration has a claimed total weight of 2,959 g (including crankset with spindle-based power meter and 10-30T cassette according to SRAM method), which is 183 g lighter than Force AXS D2. The levers feature carbon brake levers (vs aluminum on Rival), the components benefit from refined metallic finishes, and the set offers an excellent stiffness-to-weight ratio. Force AXS E2 is approximately 267 g heavier than Red AXS, the difference being mainly in the crankset, levers and cassette — with no functional performance difference.

Standards and compatibility

• Bottom bracket: DUB standard (28.99 mm spindle) compatible with threaded BSA/ITA, BB30, PF30, BB86, BB92, PF86, PF89, BB90, etc.
• Brakes: flat-mount only (Paceline 160mm Centerlock rotors included; 140mm or 180mm diameters available separately).
• Cassette: SRAM XDR freehub body required (not compatible with Shimano 11-speed HG).
• Compatible crank lengths (crankset not included): 160, 165, 170, 172.5, 175 mm.

What distinguishes the E2 version with USB-C charger

The E2 version includes the single-port USB-C charger (reference AC-EAC-BC-A2), a modern standard offering better conductivity and universal compatibility (vs micro-USB from previous generations). The USB-C cable is not included in the kit, but any standard USB-C cable (smartphone, computer) is suitable. Full charge time: 60 minutes for one battery; fast-charge function up to 75% in approximately 45 minutes. The two included AXS batteries power the front and rear derailleurs (one battery per component); each battery weighs 24 g and clips on/off without tools.

For whom and for what use

The SRAM Force AXS 2X E2 groupset is intended for demanding cyclists — amateur racers, sportive riders, long-distance randonneurs, climbers — who seek Red AXS performance without the Red budget. Ideal on high-end carbon or aluminum frames, sport road, endurance or all-road, with flat-mount disc brakes. The versatility of the rear derailleur (up to 36T) makes it an excellent choice for hilly terrain, alpine sportives or mixed roads. The absence of cables dramatically simplifies installation on frames with complex internal routing, and AXS customization
