the critical aspect of the Schwinn giant paradox: original rims 27" (uncommon), but all the more reason to install a set of REALLY FAST 700 rims and racing gears

flip it? have you lost your mind? I intend to ride this bad machine to eternity man. On that note I've decided to name her "Destiny" FAR superior to anything currently offered by giant (or anyone else) BECAUSE 1.) Chicago engineering (frame geometry) 2.) cromoly reigns. I rode a lot of bikes and the giant made Schwinn's are basically cromoly paramount frames. Giant added brakemounts for the Schwinn cross runs but left the original caliper holes where they were. 84 worldsport is a FASCINATING bike. It may be the first giant ever produced for Schwinn? The catalog suggests, to me, like chicago beta tested giant on the class of 1988

I sure wouldn't compare the 1984 Giant made frames to a Paramount. The 1984 model year started with the lower cost models being produced by Murray and Giant and that was the first year of Schwinn's association with Giant. Schwinn was also building diamond framed models at their new factory in Greenville Miss. and Richard took over the Paramount model line. There were also some models made in Japan.

Brother. I love that you're into riding this machine. There's everyone from purists to modifiers in this forum. Here's where I lean: ride the bicycles you own, that's why they're there. If you're going to ride it, don't let anyone deter you from making it your own. Frankly, all the bikes the collectors sweat over have probably been modified (sans some really glorious examples) at some point by the original owner: the young person that once loved their summer evenings spent on THEIR bicycle.

according to the interwebs, Shimano brought the first SIS to market in 84

standing there @ the thrifstore, when I first laid eyes on bessie lou's rusty pedals, I thought I'd just slap some "modern" pedals on her. But I unfortunately had to get after the chrome saddlepost with an sos pad and I just kept on going. I was 13 yrs old when they stamped that G on her, so naturally I felt a bit nostaligic. Anyway it got me to thinking how she's kinda the perfect marriage for me. On the one hand, "chicago chrome" but on the other hand, hattori hanzo forged that massive stainless chainring with an ancient samurai hammer. I'm thinking a flashy chain might look kinda tuff on there, and I KNOW them flashy pedals will be smokin' BOATLOADS of aluminum/titanium on the bike trail real soon... this is most definitely not a flipper for me...

It's going to be a better rider than anything for 10 X the price you paid.

was this the first cromoly frame Schwinn ever brought to market? I've been shopping bikes for months and this was the first one I found worth buying. I've been pedaling a trek Y for the past year and what a dreadful contraption.

Trek Y. I’ve had one for years and agree it’s not a great bike to ride, was a neat design and looked cool at the time , good luck if you decide to roll with this new project
Cheers

Found her in a thrift store 2 days ago. I checked her all over real good and I'm quite confident we're looking at the "paramount" of a century's worth of chicago frame engineering (trial and error geometry) expressed in virgin cromoly. Judging from the catalogs she may be kind of a rare bird? So I've come to defer to some highly specialized local expertise. Please advise. TIA

The serial number on the bottom bracket shell, GD841674, is for Giant from the year 1988. The first letter G is for Giant, the second letter D indicates the frame was made in the first half of the year, the first digit 8 is 1988 for the year of manufacture.

The Giant serial number for the 1984 World Sport would be on the dropouts.

That World Sport "might be worth" the $39. asking price if you're looking for a rider bike that you would not need to lock up. It was one of the lower price point models in the line. Today, new replacement tires and tubes will exceed the value of the bike. It really depends on what your needs are, it's not a flipper.

I believe the head badges still had the build date stamped in them at this time. Check out the head badge real close for a four digit stamped number and that should verify when it was built.
