Vintage Mongoose in, well... mixed condition:
Really cool Specialized handlebar and Ritchey Logic fork!
Nice Suntour Power Thumb friction shifters and Alpine/Mountech derailleurs.
20" frame is beautiful, probably fits riders 5'8"-5'11".. BUT it has a big gnarly dent in the left chainstay, see photo.
Another frame issue: rear right brake post is broken about halfway up. The rest of the post is inside the current cantilever brake, so it works fine as-is, but doubtful that you could ever replace the rear brakes.
Seatpost looks insanely scratched, not sure if there's something internally that would damage a replacement post similarly. It's about a 25.7mm.
The bike looks amazing, has decent Araya/Shimano wheels and an almost matching 175 mm Shimano crank set!
New pedals, chain, grips, cables, housing, front brake pads. Ready to ride!
I can deliver anywhere in the greater Tucson area for just $40!
