How are you liking the Wheeltop for gravel? Are you okay not having a clutch? I'm not sure I want to chance going electronic on my gravel bike. If the groupset dies, I'm usually on more remote mountain trails. I am debating converting my other road bike also to electronic. Contrary to other user experiences, my ER9 has been working perfect. Though I wouldn't mind trying the Wheeltop groupset as well.
Since my gravel bike is a 2 X 12, the old rear derailleur didn't have a clutch. The new EDS TX rear derailleur works the same as I am used to on a 2X set-up. To date, one of my 1 X 12 EDS OX rear derailleurs, the battery lasted over 5 days of very heavy shifting usage. (Approx 600 miles.)
On my 2 X 12 EDS TX on my gravel bike, the longest ride to date has been 80 miles, and the battery dropped by about 10%. I suspect I can get 800+ miles, with lots of shifting and still have battery power left. One thing that bugs me a little on the TX rear derailleur is that the magnetic recharge contact and rubber sealing boot are on the back side of the battery. I have a difficult time trying to blindly get the charging cable to sit flush and charge the battery. I end up flipping the bike up in the air so I can look through the rear wheel spokes and get the charging cable aligned so it will charge the battery.
(3 charges to date: Initial charge, One when the battery was down by 20% after initial set-up/shift trimming, and then one time when the battery was at 60% and I was going to ride 90+ miles, but this ride was cut short to 45 miles due to snow on the road.)
