I've got a Centurion Comp TA, purchased on 9/16/84 for $465. Serial no. is probably N4K8201. It's got Shimano 600 components and Champion No. 2 tubing by Tange. Wheels are Araya. Handlebar is a "Sakae Custom Road Champion". It's got downtube friction shifters. Even back then I recognized my limitations and asked them to install a 14-28 cassette. I also remember how pissed I was that just a year later indexed shifting came out. I saw some post exclaiming the virtues of friction shifters, but I can't agree since I was constantly adjusting them until they weren't making a racket.

I use this bike on my trainer now. Are bikes like these worth anything?
