I've had an L-Twoo ERX groupset for about 9 months now. I've never been super impressed with the shifting precision but for the price I wasn't going to complain too much. Today I put a new cassette and chain on and when doing so I noticed that the derailleur cage looked bent. The bottom pulley sits further outbound than the top. Immediately I figured the derailleur hanger must have be bent somehow, not sure how as this bike has never been off the trainer, but nonetheless, that was my first thought. Before pulling the bike out of the trainer and into the bike stand I figured I'd throw on the 105 derailleur I had on the bike before putting on the L-Twoo groupset, it lined up perfectly. I then put the hanger alignment tool on, it is also perfect. The only remaining thing is that the L-Twoo derailleur is bent somehow, or maybe it is just like that by default (which would be a bit weird). Can any of you out there with L-Twoo ERX drivetrains have a look and see if yours looks like mine? It's hard to photograph but you should be able to see what I mean in the attached image.
