The locking fork likely means this was a commuter bike, rather than a track bike. Possibly a 3 speed. I think that frame has fender mounts that the $2000 bike did not have.

If you really want the frame, then go online when the auction is ending. Put a bid on the frame in the last 10 seconds.

If you win the frame, then 3 minutes later put in a bid on the fork for the maximum amount you would pay (knowing you won the frame).
