New bike: 1983 Univega Sportour

I am not sure why I keep running into so many Univegas, but I acquired this bike back in December 2011 from Goodwill for $56.10. I was originally planning to either give it to a friend or flip it for a profit, but it was in such a good condition that I decided to keep it. It appears to be an upper-entry/low-mid level bike, but it looks well-built and the ride feels especially solid. There are minimal signs of wear/use, despite most of its part being original. The only thing not original in the current form are the handlebar, brakes, bar tape, pedals and the bags. It originally came with a flat bar and flat bar brake levers. but I replaced them with a drop bar and Dia Compe brake levers taken off of a Centurion Elite 12 (plus pedals).

From my readings of forums, the serial number on the frame suggests that the frame was actually manufactured in 1982 (by Miyata?), but the Suntour aRX components point it to the 1983 model. It appears that the '82 model was equipped with Shimano 600 Arabesque components, so the aRX seems like a step down. The rear dropouts look stamped, not forged, but has a derailleur hanger, which I haven't seen before. The frame material is double butted Tange Champion, so it's definitely not a gas pipe bike. I'm guessing the fork is a hi-tensile steel. The 27" rims also look like Araya 20A rims, which are double-walled with eyelets, and they're laced onto Sunshine (Sansin) Gyromaster hubs that use cartridge bearings. However, given a decent selection of rims and hubs, the spokes are not stainless steel. Overall, the bike is a healthy mix of decent and entry level stuff.

I read on Disraeli Gears that the aRX never shifted as well as the older models, but personally I think it does just fine One major drawback I do see is the steel cage because it seems to be pretty soft and I can see it going out of alignment. Maybe it feels alright just because it hasn't been used much.
I'm planning to keep all the original parts since they're relatively unworn. I do plan on changing the bar wrap with cotton ones (the current ones are those that my friend was going to throw away). I'm also going to add a rear rack so that I can use the bike for short commutes. Since the bike is a bit small, it feels a little cramped when my hands are on the drops. So I may experiment with a different length stem sometime in the future.
