How long does it take to replace 2x11 Red eTap shifter batteries?

Only a couple of minutes! To replace the CR2032 batteries in your 11-speed Red eTap shifters, simply peel back the rubber hood cover and remove the three screws on the battery hatch.  Hoods do not have to be fully removed for access to the battery.

For more detailed instructions please take a look at our eTap HRD Systems User Manual: Shifter battery replacement.
