I really didn't want to make a whole thread for this but while I was swapping the Omnium crank arms between my bikes, the drive side crank arm on one of them would not come out. I easily removed both sides on my Kilo, but on the Histogram, the drive side would not even budge. I got the left side off fine, I don't see anything keeping the other side from coming out but it just won't move.
Am I doing something wrong? Do I need to do something with the bottom bracket to get it out? I used all my force and spent almost an hour just trying to pull it but no progress at all.
