hello!

I'm trying to replace my bottom bracket b/c the bike shop told me I needed a new one (it wiggles) and my bike is getting hard to ride (there is a resistance to each cycle).

I was able to remove the dust cap after destroying it. The bolts also came off, but I can't get the crank puller to fit onto the crank. I am using a park ccp-22C. I don't want to take it to the shop because the last time I went, they charged me $10 to remove my cassette off the wheel. But i can't figure out how to get it off.

Once I get it off, I need to also buy a bottom bracket (wanted to wait to see if I could figure out what kind I needed based on my old). Any suggestions? Do you suggest buying a new crankset and a bottom bracket? If so can i get a different version (ISIS) because it is more common and cheap?

Thank so much !!!
