this 1982 trek 412 was acquired with a bent rear wheel and no seat tube decals. Apart from that the trek was in excellent condition. I think the fear derailer is not correct (suntour ARX instead of suntour vx-s) and tires were more recent and still supple. We replaced the torn seat and tape, installed new reproduction cane creek hoods instead of the cracked dia come ones (dia compe changed their name in 1996), great product which has only become available recently and compliments every restoration. A new alloy rear wheel was installed instead of the bent rigida rim which was beyond repair. We see this all the time, a great bike with a bent rear wheel which probably was too expensive to replace and the owner decided to retire the bike, a few years later he decides to sell, understanding he would probably never repair or ride it again. It's relatively hard to distinguish the Early trek models made until 1984 as trek did not include a decal for the model number and basically all trek bikes look the same apart from the frame color and the background of down tube decal. I used Vintage-trek.com to locate and analyse the serial number which showed me it's an 1982 and compared the parts and frame tubing material sticker ( ishiwata double butted chrome molibdenum ) to come to a conclusion that it was an entry level 412. according to vintage-trek:  Beginning in 1981 or 1982 (and extending through at least 1986), Trek used a subcontractor in Japan to build some frames and parts of frames. The 300 and some 400 series were a complete (unpainted) frame and fork from Japan, but painted and assembled in Waterloo. 
the 1982 trek 412 was sold a few days ago to a nice guy who had  a 10 speed which was given to him and was in poor condition it was also too small for him. he traded it and was completely thrilled with his new ride, can't blame him for getting excited, it really is a great bike.

1990 Trek 330 bike we refurbished here at Bike Boom. If your'e not familiar, Bike Boom is a used bike shop in Davis square, on the border of Cambridge and Somerville , near Boston MA. where we specialize in restoring and refurbishing used and vintage bikes and offer professional bike repair services.
Here's the original brochure from vintage-trek.com a great website for info on classic steel treks.
We replaced the rear wheel, seat, bottom bracket, crankset (shimano 105) and the brake hoods and the standard stuff, tires, brake pads, chain and cables. it has a nice indexed handlebar shifter which was popular in that era and works great, I wish we could get these today. Even though it was is an entry level trek, it has  a Tange chromoly double butted frame.It is very light and nimble and gives a great ride especially due to the upgraded crankset. It was bought by a guy who's girlfriend bought a road bike from us earlier in the season. really nice couple.
