building up a bike: installing the BBPaulCL

New frame..planning to build up the bike myself. I've never done this before, but I'm sure I can do it. My plan has been to buy the headset from my LBS so they can install it for me. How about the BB? Anything special about installing a BB in a brand new frame??

FWIW: I'm planning to use Campy parts, probably Veloce, pieced together off of EBAY and this site. This is a cheap frame to use as a bad weather/winter bike.

Thanks. Paul

As long as you have the right BB tool, the BB is no problem. Just make sure to grease the threads and start it by hand so everything lines up OK. If you don't already have it, a book like 'Zinn and the art of Roadbike Maintenance' may be a good spend of $15-20.

Have fun with the build. Just take your time and everything will be fine.

Since this is cheap frame (your words) there may be some issues with BB preparation. While it's nice if the BB threads have been chased to remove any paint and burrs, they may not have been. The best back yard mechanic solution is to take an old steel BB cup, grease everything thoroughly, and thread it in. When it gets hard to turn with a wrench, remove it, clean and regrease everything, and thread it in again. Repeat until it goes in easily. If you don't have a steel cup, then do it with Al, though you'll have a harder time if the pain/burrs are really bad.
