1983 Trek 520.
I measure the seat tube at 25" (~63.5cm) center-to-center, and the top tube measures 23.5" (~60cm) center-to-center. Trek measures center-to-top, so the official catalog size is 25.5". Standover height is 35", so this is best for tall riders.
Fully overhauled with new Dura-Ace brake cable housing (was saving this for another project, but the pewter gray is too perfect of a match), new Cinelli cork tape, new brake hoods, new Shimano sealed cartridge bottom bracket, new shift and brake cables, new tires. Original paint & decals. Has some paint chips here & there but no dents.
I've got this for sale locally at $450, but would consider $400 local pick-up or $475 shipped CONUS to any forum member with over 50 posts. I paid $200 in need of full overhaul and intended to give this to a tall friend, but it's even too tall for him. I spent another ~$150+ on parts (tires, cables, housing, Cinelli tape, new BB, new brake hoods, replacement saddle), and lots more than $50 in labor. Not really making any money on this one. Just hoping to find this tall bike a good home.
