I am servicing cup and cone bottom brackets - I want to buy the most versatile tools needed, and I plan to make a fixed cup tool (Sheldon's article).
What isn't clear to me is which pin spanner and/or lockring tool I should buy that gives the most potential use?
I see that green SPA1 a lot on webpages, but don't know if that means it's the best one. The lockring tool looks pretty standard.
Thanks for the advice!
