Everything you need to know about the SRAM Red AXS E1
How the component works, which specifications matter and what to watch for when choosing. From the basics to the details real bike nerds care about.
Speeds2x12
More gears can give smaller steps but do not tell you how easy climbing will be. Climbers and loaded riders should consider the lowest gear; fast flat-road riders cadence steps and the highest gear.
ShiftingAXS electronic, fully wireless
Electronic shifting offers light, consistent operation but needs charged batteries. Mechanical shifting needs no charging and often suits tighter budgets. On gravel, chain control and the right derailleur also matter; choose a coherent package.
BrakesHydraulic disc
Hydraulic disc brakes can provide strong, controllable braking, especially in rain and descents. Rim brakes require a suitable frame and braking surface. For loads and long descents, consider the complete brake, rotor, mounting and heat-management combination.
GenerationE1 (current)
Model code and generation identify the exact component. Similar names do not mean identical interfaces or specifications. For upgrades and replacements, version and model year matter; the newest version may not fit your bike.
