SRAM eTap Battery Front Or Rear Derailleur

Since the batteries are universal, buying 1 or 2 extras means you are never caught with a dead battery 5 minutes before a ride. The included cover plate protects the contact points during transport or storage and has a selector switch so you know the charge state of all your batteries. Even if you do lose power on a ride, simply swap them around to run the rear derailleur and make it home.
