Inherited a new bike! Schwinn 974!

My father in law used to ride with the Wolverine Sports Club here in the Detroit area, 20-25 years ago. Well, he noticed that my wife and I have been riding/racing on our road bikes. He hasn't ridden his former race bike in over 10 years, so he decided to pass it down to me (which really means alot that he decided to give me the bike). He bought it new in 1990 I believe. What blows my mind is how clean this bike is! Full Tricolor Shimano 600 groupset, aero Campy bottles, he included everything, including some huge Bolle sunglasses with interchangable lenses, and a few sets of pedals/cleats and the kick-ass early 90's Look shoes!

It needs new cables/housings, and just general maintenance but this thing really is mint. Not a scratch on it! I'll get some better photos after I get it cleaned up, but I'm totally stoked to get this thing in riding condition!

:-)




If anyone has any 7 speed STI shifters, that's the only thing I'd love to do to it is put some early 7 speed brifters on it.

:-)

Will early 8-speed 600/Dura Ace Brifters work with the 7 speed rear?

Screamin...,

I read your thread yesterday and wanted to congratulate on the gift from your father in law. He is very generous. Can't wait to see it all polished up and in focus.

I can't answer your question about the 8 speed brifters working on a 7 speed freewheel or cassette. My guess is the spacing is different and there might be a problem. 7 speed Sora brifters are out there. I was able to buy on ebay NOS ones one a time for a reasonable price. In my case I needed the left hand one to shift a triple.

Currently on ebay there are several 7 speed Soras. Check these out, not all are 7 speed.

Thanks for the links! I'm trying to decide what would be better, some period era 7 speed brifters, or some more modern Sora (albeit, lower end) shifters....hmm...

I'm quite excited. I happen to know that this was his pride and joy for many, many years...so I'm excited to get it out and on the road. I currently ride a more modern Alu/Carbon bike, but want to get out on this one From what I've read, this was quite a piece of technology for Schwinn back then!

I'll get a few better photos in a few days (Just had a Time Trial on Sunday, and work has been nuts).

These are the 7 speed Soras I'm using on my '83 Paramount. In my case I'm using a 7 speed Suntour ultra freewheel, a 10 speed Campy Centaur RD and Sora Triple FD. They all work well together and I've not had any problems with the Brifters. My only complaint is my thumbs are too short to reach the inside shifting lever from the drops.

That looks like it might be the way to go. Trying to pick up an old Shimano 600/RSX shifter set in good condition is going to cost as much as some newer Sora shifters. I'll have to find a double front shifter though, as the Schwinn has a double crankset, and I'd rather keep the original groupset intact (sans shifters).

BTW, you'd have to have some ABNORMALLY long thumbs to be able to hit the tiny thumbshifters while in the drops. You really have to shift from the hoods on a set of Sora levers.

Thanks! I agree, it's a great color! The aerobars might have to go though...I'm not too big on aerobars.

Great looking ride! I happen to think that the early Brifters are attractive in their own sort of way!

Old sachs 8sp brifters (read campy) work on some 7 speed freewheels perfectly but I can't remember if it was shimano spaced 7s or not, hunt around and you'll find more info.

8 speed ultegra STI levers will work fine with 7-speed SIS. The derailler and cog spacing are unchanged from 7 to 8 speed, there is just and extra cog on the stack (thus the need for rear dropout spacing to increase from 126 to 130mm). You will just have one extra "ghost" shift in your 8-speed lever that does not get used.
Note that using STI levers may also necessetate switching to dual pivot brake calipers to retain correct braking control.

pre 1997 dura ace 8-speed shifters will give you trouble because they are setup for different derailler geometry that only dura-ace used up to 1997. Work around for using DA shifters with ultegra derailler is the B-cable attachment as shown at;

He is done with road bikes, as it seems. This is the first time that this particular one has left the garage in 10 years!
He rides an older Schwinn Cross-Fit or something of the like, that he uses to commute every day on in the spring/summer/fall. Infact, that Schwinn that he still rides is at least 15 years old, and JUST got it's first tune-up last summer. I can't believe that he never had issues with it.

Great bike, Screamin. My first road bike was a 564 and I still own it. I don't know if it's the stiffness or the geometry or both, but those frames just feel quick. I also enjoy how quiet the hubs and shifting are. I have toyed with the idea of modernizing mine's setup and even bought a hyperglide body and cassette along with non-biopace rings to replace the original equipment. But I do have 2 bikes with brifters so I ended up keeping it stock.

But anyway, enjoy the hell out of your new ride and post more pics when you finish your set up.

Shifters have arrived. Picked up some downtube cable stops for $1.50 each at the LBS, got new cables and housings...

Guess it's time to wrench on the bike tonite!

Gah, $1.50? The shop I usually buy parts has them for $15 or so, and the co-op didn't have any. I need to start wandering into the shops that actually sell new bikes...

Yeah...The guy didn't know what they were..he dug them out of a parts drawer. They are kind of grimey, as they must have been a take-off at some point. He was like "umm..I dunno, how about a buck fifty each?"
"SOLD" I said.

Well, ran new cables, installed the cable stops, wrapped the bars...Love the look...





I do have a few questions, it seems that the angle from the cable stops to the BB shell for the cable routing seems kind of odd. Does it look right? I haven't attached the cables to the derailleurs yet...but it just seems a little odd. The cables also touch the downtube. Do I need the little rubber grommits like on the modern bikes to prevent the cables from touching the downtube? Ideas?

Not that I've ever installed a set, but I want to say they are swapped left/right, so they are up side down, and the cable is coming out above the braze-on rather than below like it would out of a down tube shifter.

True...the barrel adjusters on the two are different. I figured the one with MORE adjustment in larger incriments was for the front derailleur....maybe I'm wrong? Any ideas?

They look like this:

As you can see, I put the one with the little lever on the left side for the FD....maybe this was wrong?!

*edit, after looking at the Retro Roadies with STI/Ergo's thread, I've decided that I definitely have them swapped right to left. Question is, does it matter which of those cable stops is for the FD and RD? Are they specific?

Swap them. Dura Ace style one is on the right for the RD and it puts the cable at the bottom, for the right cable line.

Cool shoes
