SRAM / Rockshox Etap / AXS Battery

If your bike is AXS-equipped, you have at least one rechargeable SRAM AXS battery. Capable of powering a whole host of AXS components, these tiny power units are interchangeable between parts on your bike, easily swappable during a ride, and fully rechargeable in an hour or less. The same battery is compatible with front and rear eTap AXS derailleurs, Eagle AXS derailleurs, Reverb AXS seatposts, and Flight Attendant suspension.

At just 24 grams, an AXS battery is lighter than the energy gel in your cargo bib pocket.

Features

• Charges in 60 minutes or less
• Same battery design for all AXS™ components and original SRAM RED® eTap®
• Real weight: 24 g
  

Should you carry a spare?

Your AXS batteries bonking mid-ride is unlikely, as they will last hours upon ride hours depending on component:

• Road derailleurs: 60 hours
• MTB derailleurs: 25 hours
• Dropper posts: 60 hours
• Suspension: 20-35 hours
