The bottom bracket sits in an aluminum sleeve that is attached to the carbon. If that sleeve is loose, it can be a real problem. Some say it can be re-glued, others say no. Mainly, see if the bottom bracket grinds or makes any noises. Another thing to do is to hold each arm of the crank set and gently rock. There shouldn't be any play there. If there is, have the bottom bracket and sleeve checked. Someone mentioned preferring external cups for this bike and that makes sense. Kevindale's advice should be followed.


As far as the make, I've attached a photo of mine. Serial number and place of origin are on the bottom of the frame. There's a lot of good info and you may find this thread good reading. It is a thread by Kevindale. http://www.bikeforums.net/classic-vi...l-200-sci.html


I can't say enough good about these old 200sci's. They are quick and you can opt to make them look somewhat vintage or modern.
