I feel like an idiot asking this question but like all in life, you learn from your mistakes (or stupidity, haha).
I'm trying to take the original Shimano 105 cranks off a Miyata 310 I picked up this weekend.
I took off the 13mm nuts and cant for the life of me slide the cranks off. I've tried oiling them up and nothing. I really didnt want to start hammering away at them and risk scoring them.
Am I supposed to be using a puller to get these off ?
