Also thought perhaps it could have been a dedicated hilly TT bike, but that would have been quite an indulgence for a junior rider.
New paint with a filed-off front shifter tab is a possibility, too.
I'm guessing that it might be very early 80s. I wasn't aware of funny bikes until the 84 Olympics.
The over the BB shell cable guide makes me think older than 84. The wheel guides have the CPSC plastic covering and the rear dreailleur limit screw has the cone of shame. Around what year did they quit using forcing those on us?
