80's Schwinn World Sport- Looking for specs and info

Hi everyone!
This is my first contribution so I'll first start with a personal introduction. I'm a midwesterner, (so I have to make the best of my bike riding during the spring to fall seasons) in my forties, and am married with a 13-year-old son and 10-year-old daughter. I am the most avid bike rider in the family with my daughter being the second. I'm am not a bike expert or bicycle "fanatic", just someone who likes biking on long rides and biking f-a-s-t.

Just a warning, my writings tend to be very lengthy!

Anyway, I just purchased an 80's, black with silver lettering, 14 speed, Schwinn World Sport and I love it! It is in like-new, excellent condition and was just tuned up at a local bike shop where they did some minor adjustments and lubed it. The only change that I had done was to have them replace the rear knobby tread tire that came with the bike, with the same smooth-style type like the front tire. I have owned three mountain bikes, an 80's Schwinn Mesa Runner, an '03 Diamondback Outlook and an '03 Mongoose MGX and after riding in two MS Bike Tours down Lake shore Drive (this annual bike ride was discontinued) I knew that I really wanted a lighter weight road bike instead of a mountain bike. In one of the tours, I borrowed my brother-in-law's lightweight Trek mountain bike and realized that I could really "fly" with the lighter bike and it was less tiresome. I used the steel framed Mongoose with dual suspension on my very first ride and it was a total bear to ride! It must weigh over forty pounds! Anyway I decided that I didn't want to spend $$$ on a brand new road bike at a bike shop so I looked into the Schwinn Prelude and GMC Denali from Target and Wal Mart. It was either this or buying a used road bike either from local ads or from the classifieds in Craigslist. I knew that any used biked from a bike shop would cost way above my budget. After reading forums like this one I steered away from the department store bikes and concentrated on looking for a decent used road bike. I only considered the store bikes because I had gift cards from both stores that would put them within the budget I had to purchase my future bike which was $100 or under. My brother-in-law found one on Craigslist and test rode it for me. He is a veteran triathlete so I trusted his opinion. He said it rode well and that the frame and components were in great shape except for the worn out after market seat. From the condition of the bike I think maybe the seller switched the seats because I don't think that the bike was ridden as long and as hard as the seat's condition would indicate. Anyway, I knew I had an aftermarket, Schwinn, split racing-type seat that I had on my Mongoose to replace the worn out one. It is silver and black so I knew that it would also match the bike's color scheme perfectly. My brother-in-law wound up buying the bike for me for only $40! He had bargained down from the seller's asking price of $80. Even with the tune-up my brother-in-law suggested that I have done, the total cost of the bike was definitely within my bike budget!
Like I said earlier the tune up came out to be less than I thought so even with the new tire my "new" vintage Schwinn World Sport was a bargain at under $90! I have attached a photo comp of it for you all to check out. Being my first ever road bike, I am totally happy with the bike and its performance!

But now I would like to know more about its history and specifications and that's where I know this forum
was the right place to find out. I don't know anything about the bike other than what I have already written here. I know it has a chrome-moly 57cm frame which has written on it "Made in China." I was a little apprehensive when I saw this but seeing that he bike has lasted this long and is still in great shape, no matter where it originated from, it's definitely well-made. The head badge says "Schwinn Quality." Could somebody give me an idea around what year the bike was actually produced and other specs like its weight and reliability. I know all of this is "after-the-fact" and doesn't really matter because there is no way now that I am giving up the bike, but I would just like to know more about the background of my new "ride."

Thanks in advance for your input and help!

I have the same bike.

I built it up as a single speed with 700c wheels and it rocks.

Currently, it is apart , hanging in my garage because I have a fixed gear bike that is much smoother, handles better, and has a much stiffer frame. I overcame the chain slack issues by employing a chain tensioner.

ohh well, here is what it looked like before I dismantled it:

Awesome Ride!

Nice bike even before your mods. I can imagine what it looks like now. Be sure to post a new picture when your project is done.

Do you have any info on the World Sport, when this particular model was produced,how much it originally weighed, etc.? The four numbers on the head badge of my bike read 1910. What do these represent. I knwo they are some sort of manufacturer's code,right?

1910=191st day of either 1980 or 1990 (which decade is determined by the decals, components, etc.). If it's a 14-speed and has a chrome-moly frame, it's probably a 1990 model which will look something like this '89 or this '91 (Tom doesn't have a 1990 catalog to scan yet).

The 1989 specs are HERE, and the 1991 specs are HERE.

SCOOPER,
Thanks for the reply and very helpful info, especially the scans of the specs. You are probably right in the bike being a 1990 model because I checked a forum that had actual Schwinn catalog pages scanned from 1979 to 1989 and none of the World Sport or Schwinn decals on any of the bike frames matched mine, including the bikes from 1980 which would have been possibly the year my bike was manufactured in. I was dismayed a bit about it's weight though. It seemed lighter than the 26 pounds that your scan of the 1991 specs would indicate, but I guess that was because I was comparing it to my other steel framed, over forty pound, Mongoose dual suspension mountain bike.

Is my bike not as sought after as the previous World Sports because it is made in China? The worst that could happen is if Schwinn decides to resurrect the "World Sport" name again and starts selling it at Wal Mart and Target stores, just like they did with the "Prelude" and "Varsity" models. Speaking of these, I checked out the current Prelude on sale and it didn't seem too bad. Fairly light with an aluminum frame, Shimano derailleurs, 27" narrow racing aluminum rims and pedals with toe clips to mention a few of its features. I actually considered one of these before looking for a used, vintage Schwinn. Did I make the right choice or should I have waited for an earlier Word Sport model? I am not a bike "fanatic" just an entusiast and this is my first road bike ever. I ride mainly around the paved streets in my neighborhood and nearby bike paths, if I'm lucky, twice a week, so my World Sport is perfect. Plus it is in such great condition even after 17 years. Did I make the right choice or should I have waited for an earlier Word Sport model?

Thanks again!

I think we would all agree that if you enjoy your bike, it's the right choice for you.

Don't worry, we may have you infected with that vintage bug even if you don't realise it yet .

Glad to hear you like your World Sport. I actually just picked up an early 80's (need to check the head badge) lugged 10 speed World Sport. It is a pretty nice riding bike, I just need to replace the chain and clean it up a bit.

John, Nice bike. Certainly a bargain for the price you paid, that includes the cost of the tune-up and tire. I like that color Schwinn too.
After your ride it a while, I would make one change. I would swap out those brake levers for some Tektro Aero brake levers. They will substantially improve your braking power. Happy riding.

To one World Sport owner to another!

Business810,
Thanks, yeah, I really LOVE the bike and riding it, especially after being used to riding only mountain bikes.

Be sure to keep in touch with me with the progress on your '80 World Sport! I'd love to see how it looks and what you've done with it.

Isn't it a great feeling to find such a good deal?

BTW,
Those head badge numbers are pretty faint. I didn't even see them on my bike until I really looked close and hard.

roccobike,
Thanks! Yeah, I was very lucky after searching on Craigslist for over a month and my brother-in-law finally finding this "jewel" for me! I am still amazed what good shape it is in. You can tell it had never been ridden hard and had been very well taken care of as was evident in the low price of the LBS tune-up. Like you, I like black too and that was the color I actually was hoping to get. My 04 CR-V SUV is also black.

Your brake suggestion sounds good. Are they expensive and should I let the LBS install them? I'm no bike mechanic or Mr. Handyman for that matter either! I will consider them in the future.

Happy riding to you too!

Speaking of good deals, did I mention I only paid $25 for it? I'll check out the head badge tonight and try to clean it up a bit more to post some pictures.

JON,
Awesome deal! Even with the minor parts replacements and clean up you should have an even finer ride! Good luck with your "project."

Can't wait to see the future pics as you progress!

Well, I looked at the number on the head badge, and I was way off on the year. The badge reads "537" - which would place it as a 1987. I looked at the '87 catalogs on trfindley.com and the decals and lugging appear to match. The only thing is that it is not a World Sport, it is just a World. The decals seem to be the same between the models, but they have a different drivetrain - 10 speed SunTour components instead of 12 speed Shimano.

I replaced the derailleur cables and the chain, both of which were rather rusty from sitting unused for many years in the back of a LBS. It seems to shift well on the repair stand and all of the bearings seem to spin well, so tomorrow after work I'll take it out for a ride. I'll probably end up repacking the BB just to be on the safe side. Overall, for a grand total of less than $40, it should make a very nice commuter that I don't have to worry too much about it getting stolen.

JON,
Thanks for posting the pics.Your bike looks great overall! You are much more of a bike person than me! I have never replaced any bike components whatsoever except simple installs like a seat, bottle cages and handlebar basket. I would have saved paying the LBS if I knew what you know about bike repairs! You can tell you are a bike "aficionado" by that bike stand too. I've been noticing more "bike people" online use them, I guess, for repairs and in place of using a kickstand.

Are those indexed shifters or "click" shifters? You can tell I don't know the exact bike lingo. I mean by indexed as shifters that you have to hold in place for the gears to engage or "click" shifters where you just have to click into gears with positive detents. Does your World model have a hi-ten steel frame or chrome-moly and how much does it weigh? The factory says my '90 World Sport weighs a little over 26 pounds with the chrome-moly frame and steel fork. What is your frame size? I'm not sure about mine but its stand-over height is about 33". All that I know was that mine was advertised as a 57CM bike, whatever that measurement is from, I'm not sure. How are the tires? They look in pretty good shape.

I have attached a cleaner and larger picture of my bike.

BTW,
How are you able to upload such a nice, large, clean pictures under 100KB which this post says is the upload picture size limit? I find that I have to reduce the overall picture size in order to keep a decent resolution.

ENJOY THE RIDE!!!

John

John,

I think I have you fooled about my bike knowledge. I just started working on bikes a lot this summer, but I've worked on cars for years so I figured that if I can handle repairs on automobiles, I can handle them on a bike. So far, I was right on that, but I still have much to learn. I came upon the bike stand by pure chance; it was on craigslist one night for $50.

My World has friction shifters, not index shifters. I'm used to friction shifters, so I don't mind at all. The frame is not market as either hi-ten or chrome-moly, but it definitely weighs in at under 30 lbs. I don't have a scale, but it's not too heavy. The 57cm measurement is likely the length of the seat tube from the bottom bracket to the top of the tube. My frame measures 25" (63.5cm!) along that same dimension. I never thought I'd say this, but the frame is almost too big for me

I believe my tires are the originals; they still have the "HP Sport - Schwinn" sticker on the sidewalls. They are in great shape with no cracking or anything.

BTW, to keep pictures small, I upload mine onto a webshots.com account and then link to them here. I have no problems with size then.

JON,
I have a question. I haven't used indexed (click) shifters like the ones on my bike which has 14 speeds. I am more used to the grip shifters on my previous mountain bikes that have the number of the gears printed on the handles. It seems that the left shifter doesn't have as many gears to "click" into as the right lever. Can you please give me a quick "how to shift on a road bike" explanation and how the number of gears is split between the two shifters?

I'd appreciate any input!

John,

To give you a quick basic, the left shifter controls the front derailleur shifting between the two front chainrings. The right shifter controls the rear derailleur shifting among the seven cogs in the rear of the bike. That's why the left shifter should only have two positions whereas the right has seven. The two shifters combined give you your 14 possible gears. As you move the levers downward the bike will shift onto larger sized cogs. In the rear this will make it easier to pedal, in the front more difficult. You do not want to use the smallest chainring with the smallest cog on the freewheel or the largest chainring with the largest cog - crossing the chain like this can cause accelerated wear on all of the moving parts. Aside from that, my best advice is to just try shifting around and see how the different gears feel.

If you want a more mathematical approach to how the different gears compare, count the number of teeth on each gear and plug them into this calculator: http://sheldonbrown.com/gears/ It will show you the comparative ratios and speeds you can achieve in each gear.

It's hard to describe all of this just by typing. Hopefully all of that makes some sense, and if you need anything clarified, feel free to ask...

Jon

John - I wish I had thought of your site name. I too am John and I too just bought an 80's World Sport. Only $25 on Craigslist. I've gone from not having ridden for 25 years to riding anywhere from 100 - 150 miles a week. I just took it to Hilton Head and rode 30 miles a day in mid-90's heat. I love the stupid thing. I can't beleive I was considering a comfort bike from Target. Yikes!

I can't beleive I was considering a comfort bike from Target. Yikes!
I actually found out that I have a 1990 World Sport not an '80's, but still a Schwinn, and still a World Sport.
You've been bitten by the "biking bug" and the World Sport will do that to you!

I wish I had more time to bike as much as you can! But hopefully I will squeeze in more time.

I've attached a picture of my "ride" for you to see.

ENJOY THE RIDE AND RIDE ON!!!!

The right shifter controls the rear derailleur shifting among the seven cogs in the rear of the bike. That's why the left shifter should only have two positions whereas the right has seven. The two shifters combined give you your 14 possible gears. As you move the levers downward the bike will shift onto larger sized cogs. In the rear this will make it easier to pedal, in the front more difficult. You do not want to use the smallest chainring with the smallest cog on the freewheel or the largest chainring with the largest cog - crossing the chain like this can cause accelerated wear on all of the moving parts. Aside from that, my best advice is to just try shifting around and see how the different gears feel.

If you want a more mathematical approach to how the different gears compare, count the number of teeth on each gear and plug them into this calculator: http://sheldonbrown.com/gears/ It will show you the comparative ratios and speeds you can achieve in each gear.

It's hard to describe all of this just by typing. Hopefully all of that makes some sense, and if you need anything clarified, feel free to ask...

Jon
JON,
Thanks for the tips! I tried out shifting the other day. I found out that I did have both the front and rear cogs on the smallest sizes, something you advised not to do because of excessive wear and accompanying noise. When I changed the gears away from this set up I could tell the reduction in the noise that I was hearing slightly before. I wondered where it was coming and now I know thanks to you!
I found a perfect gearing set up to cruise the mostly level streets around my neighborhood.

Thanks again for your help! I guess I will learn more as I gain experience shifting.

FWIW,
This is what the decals on a 1980 World Sport look like. It is not in it's original configuration. I bought it in 1985 in a thrift store and replaced the steel rims with alloy (Wolbers), installed a Suntour 6 speed freewheel (12-34), Suntour ARX dérailleurs and shifters and added fenders. It was my everyday commuter for several years thereafter. It is still in fine shape and sees occasional use when the weather is awful.

DOGBAIT,
That's one fine ride that you have! I really like how you've restored it and modified it. Your accessories fit perfectly with the bike's image. I know my bike isn't a 1980 like yours because I checked my bike against some online scanned 1991 Schwinn catalog pages (1990 catalog images were not available) <<http://www.trfindley.com/flschwinn_1991_2000/1991_26.html>>and I definitely have a 1990 World Sport. The decals closely match my bike's and the specs match including it being a 14 speed with indexed shifters and not a 10 speed with friction shifters like the 1980 models. Also the manufacturer's code on my head badge is 1910 so I know it was made on the 191st day, which would be July 10th, in the year of 1990.

I checked out your other bikes too and not only are you one serious bike dude, you are a great photographer and have taken some awesome shots of your bikes! How do you get to upload your pictures in such a large format into this forum? I try to, but in order to be under the 100KB restriction my images come out very small in order to keep a decent resolution. At the suggestion of another contributor in this forum, I tried using the Webshots website to manage my images and then link to it but I run into the same problem. Any advice would be appreciated.

Here is a photo comp of my 1990 World Sport <<http://thumb6.webshots.net/t/30/31/3/95/81/2434395810102023286BeDCDc_th.jpg>>

I've also attached an image that I was forwarded which I think bike enthusiasts will appreciate. If you can believe it, this was actually carved out of a watermelon!

DOGBAIT,
Here's hopefully a larger and better image of my bike...


I think I finally got this photo thing down!

I just picked this up today I think it's an '84. All original except for the seat.
