I don't believe Giant marketed their own name bicycles until the late 80's or early 90s. Suntour GPX was introduced in 1989, and it is index shifting. I believe it was Suntour's top of the line that year for road bikes but I'm not 100% sure of that. The bike in the picture also has aero brakes. Looks to me to be about 1990 vintage. IMHO $200 seems a little high but not crazy out of line. I would expect a bike like that to sell for $125-150.

I believe Giant has always produced their own tube sets. Roger

I have a gian allegra that looks so much like that one. Has the same suntour stuff on it. I cant find a any info either. I need to get the rear drop out brazed before I can ride it. The bike looks fast just sitting there broken, and the parts set is real nice. Up the road in philly I could see it selling for $200 or on ebay. Try and talk the guy down of course.

Mid to upper range, not top of the line. It worked well though.

No idea of the model name or tubeset. Look for decals on the seat tube to tell you what tubeset was used. You should be able to use that Vintage Trek internet site to date the Giant, if you buy it, using the date coding on the Suntour components. Works for me almost every time.
What type of tubing? Looking at the year and level of components I'd be real surprized if it wasn't at least Chro moly main frame. Possibly double butted, Chro-moly throughout.
IMHO Giant doesn't get nearly the respect they deserve. That's because they didn't market their name until much later than Trek and other names. Some of those lower-mid range Schwinns that are posted here from time to time have a "G" and four digits stamped in one of the rear dropouts. Those frames were made by Giant. They may not be high end, but they're nice bikes that make good knock around bikes. I have a 83 Nishiki Sport and a 84 Schwinn Traveler with frames made by Giant. Both show signs of previous miles by their original owners, but were maintained and still look good and ride good today.

Thanks, no I'm not into fixies. That's pretty much how I picked up the Schwinn at a yard sale. I'm planning on doing a complete clean up later this summer. If you come across one of these old Schwinn's with a Chro moly frame, buy it. IMHO these frames are really smooth riding. Giant made some pretty nice bikes for Schwinn.

have you emailed the seller yet? I think I see an A on the top tube in the back end photo. If it is an alegra it is cromoly triple buted and light for a steel bike. There seems to be the right number of blue blurs on the top tube for alegra when I blow up the full bike photo. My moniter isnt very good.

The GPX group indicates it is 1989 or 1990, which should make it an Allegre. Originally sold for $500 US in 1990, From the specs, it appears to be your basic club racer for the era. GPX was decent equipment and about 3rd in the SunTour hierarchy. Unfortunately, it got lost in the consumer hype over Shimano's SIS. These days it can be difficult finding Accushift parts if derailleurs, shifters or cogs need replacing.

I did email the seller, but I haven't heard back yet. The more I look at the bike, the more I like it. I'm not really worried about parts failing, bc the replacements would most likely be a rocket ring and a single cog : ).

I cant understand why the seller said the bike was not pretty, unless he meant the paint was beat up, or some other aesthetic reason. That bike looks great IMO. It has the classic road bike geometry. As far as the tubing goes, it could be 'Ishiwata' cro-moly, maybe even double butted. I had a comparable 'Fuji' bike from around the same era. Look for a sticker or something that has the olympic inter-connected rings, an indicator of mid 80's to early 90's "Ishiwata" special lightened cro-moly steel tubing.

Nice bike. Not Italian, but nice. Japan made some nice bikes.

I'm guessing he means chips in the paint that aren't visible from the lo-fi pics.

Has anyone done any creative no-budget paint scheme modifications? (e.g. electrical tape, stickers, vinyl coating..) I'm trying to think of what I'll do if I get bored with white

If anyone's following, I met the guy for a test ride. I would have bought the bike in a heartbeat, but it turned out to be too large for me. The standover was too high by about an inch or two.

It was pretty, though. The paint was in great shape and the drivetrain was smooth. Oh well.
