I thought I'd update those considering the eGR. I bought good quality batteries and have only charged them once. I've been on about 15 rides so far (ranging from 20km - 80km) and the batteries are currently sitting at about 72%.
I've had it on my bike for two months if that's of any worth?
Well, it worked for most of us when it was still brand new. Fingers crossed that yours will keep working.
While we're on the topic of eGR: We still don't know whether LTWOO's electronic groups are cross compatible. Does your battery holder have two cable ports and one is left unused? Is it the same 3 pin plug? Because 80 Designer Store promotes the egR with having a "2024 new" battery holder. Yet on the photos it looks exactly the same.
Also, I wonder if the left shifter buttons can be used for something else at some point. For instance to turn pages on Wahoo or Garmin computers or control a bluetooth dropper.
It doesn't really make sense that LTWOO went through the trouble to come up with dedicated gravel brifters and sell these with buttons on both levers when they don't even make a 2X gravel groupset. They'd be selling dead weight and lose money in the process, right?
Otherwise one might as well strip the left shifter.
