What do I do…..?! Can’t get my cranks off my bike. It’s this bike and with those cranks…. I took out the allen screws but It wasn’t coming off. Went to the shop asked them and the guy there said you just have to lift up this “tab” and it should come right off. I lifted up the tab but the cranks didn’t come right off! What do I do?? If you could help me that would be very much appreciated.
