Hey guys, I need some help. I really just need to make sure im not going break anything on my bike. So I picked up a new chainring today after my last one took a beating. This is my first chainring swap so I had a shop take off the crank arm. I was told I could put it all back on relatively easily. I have an Octalink Crank arm. For some reason I cannot get it on. I match everything up, and it just wont go on. I even took a rubber mallet and tried to force it on... then thought better of it.
My question is: Is there anything I am missing?
Also, I am doing this myself mostly so I know how everything works on my bike better, but If need be, I will have the LBS put it back on, but I am trying to slowly become independent of the Local Bike Shop.
