Hello folks. I have a 2004 Giant TCR Aluminum with a clicking bottom bracket. It is worse under load, but if I spin the crank with no load I can hear it making slight grinding noises.

Examining as best I can (with no tools) shows: Campagnolo 1.370 x24 TPI. I guess (one of) my problems is that I don't know all the specs to buy a new one. And I can't find anything online on this particular bike.

Things I would very much appreciate help with:

- What BB do I need?

- What tools will I need to get the job done? I'm on a budget!

- Can I swap from the current crankset to an FSA compact with no issues?

THANK YOU!!!
