I finished my build tonight (or should I say "this morning") and couldn't wait for the sun to come up to take a picture and share it!
(I swear the camera distortion is making those brake cables look longer than they really are, though even without the distortion they're a bit too long.)
The budget as it sits now:
Original purchase: $60
Paint and primer: $18
Bottle bosses: $5
SunTour 7 front derailleur: $5
Handlebar tape: $8
Cables (scavenged from garage scraps): $5
Current total: $101
I bought some decals from lettering.com that I think look pretty close to the original, but unfortunately they'll have to sit until the challenge is over because I don't have room left in my budget for them. O, the sacrifice!
