Ha! I'm not a pro with gears, so I don't really change the front ring a lot. My flat is on an incline and I just knocked through gears to glide up the hill. Going up swarns was the first time I've used the inner ring since building the bike.
I don't think the wheels are 11 speed. They were bought off ebay as a used tester Wheelset from a bike shop. The cassette fits fine with no movement.
Might it be something to do with the angle adjustment of the derailleur?
What are you doing in that gear?!
If you're on 10 speed and the wheels are 11 speed you might need a spacer?
