Small or small medium

Hello all,
I have a frame with serial number 408Y3SM.
Few questions?

1-I assume it is a small/ medium and not just a small--is this true?
2- What size headset and bottom bracket do I need?
I plan to build her up, but already bought a wrong headset, got 1" and too small so I again assume it must be 1 1/8"

Thank for your time

1993 Small-Medium frame, should be 1" headset. They switched to 1 1/8" in '95-'96 timeframe.

Bottom bracket is standard 68mm threaded.

Unless the head tube was replaced somewhere along the way, it would be 1". We never made any 1-1/8" head tubes in Somerville.

Yes, the SM in the serial number indicates that it is a small/medium

Good luck
Scott
