I was thinking of going to shop but i want to learn it myself rather than relying on the shop all the time. I ask too many question in the shop, they tend not to answer cause that is how they make their living.

Campy Crank, around $180 on eBay or I see the wrong one?

I do my own cleaning, adjustment, wheel tuning/truing, chain adjustment, and etc but just couldn't figure out BB. BTW, english is my 3rd language so some times i get lost.

Thank you.
