The dropouts (rear and fork) are Columbus but there are no other identifying marks to determine the steel type or manufacturer of the bike. The BB does have a four number Serial Number "3879".

1) Is the frameset Pearson or Cinelli?
2) Pearson frameset with Cinelli BB and lugs?
3) If the dropouts are Columbus, is it likely the tubes, stays, and fork are also Columbus?

The frame with the Campagnolo headset weigh 6.02 pounds with a 55cm top tube and 57cm seat tube.

I'd post pics of it but I have not reached 10 post yet.
Cinelli BB's were used on zillions of frames. Add some pics to an album on your profile page, they may get moved here.

Respond to all posts and replies here to get to 10, it may take 2 days X 5 to get there.

And welcome aboard, glad you found us.
