Thanks CravenMoarhead. I have a chain tool so I guess I just need to bite the bullet and get a lockring wrench.
The cup on this bike looks like it just accepts a regular wrench so I should be good there. What do most people use to apply grease? I know there are grease guns, but is there some other trick that anybody has come up with to do it without one?
When I'm off work I will go to the bike shop and see if I can get some bearings and cotters. I'll report back with how it goes. Thanks everyone.
