I decided today to try removing this pin from Keri’s Robin Hood. Let me tell you, this is what a really messed up bicycle cotter pin looks like when you finally manage to get it off the damn bike. Bike shop, which shall remain nameless for now, did not file the pin to the correct shape before installing it. Grrr!!!!!!!!!
The good news is that the crank on the bike is not damaged at all. I just need to go pick up some new pins and file them correctly. Sweet!
