1986 Schwinn World Sport?

Welcome me. My father bought a Schwinn bike in the 80s I remember. I was with him. I remember him spending a bunch of money on it, and I remember him never riding it. Over the years I dealt with trying to ride my mountain bike in the city and it suxored. So I stopped and continued to ride my gas guzzling truck to work. The other day at my pop's I asked "Can I have your bike, you never ride that thing?" He gave it to me.

I am now a proud owner of a 1986 Schwinn World Sport. Silver and completely original. Tires are rotted and brakes are poor. I know it needs a ton of work to get her back in shape, but I am really excited about owning this.

First, I don't know if I should restore it or make it a fixie. Always wanted a fixed gear so I can loose the chub.

I have the following numbers on the bottom bracket : G0786 and 616X239 (X=some number) Is this an 86?

It says 4130 which I think is something about the Chromolly frame?

Would I really mess this bike up by taking it all apart and putting back together? I used to dissemble this type of stuff when I was younger with little freestyle bikes. How uber is this to do?

Thanks!

I believe it is a 1987. Whoops I forgot the pictures. This is my 1987 and has a similar serial number. It should have a small stamped 4 digit number on the head badge the will tell the build date. First three numbers are the day of the year and the last is the last digit of the year. Roger

Older bikes are fun to ride, and NOT expensive if you keep them as original as possible. Take your bike to a good bike shop and get all the bearings lubed and adjusted, and get the shifting and brakes tuned. New tires, and you are ready to go.

Many of the lower priced Schwinns of the mid-80's were made in Taiwan. As much as we all love Chicago-made Schwinns, the Taiwan-made Schwinns were generally lighter, and used better grades of frame tubes and components than most Chicago Schwinns.

Avoid the temptation to try to convert a 1986 bike into a 2008 bike. You will spend a bunch of money, but you won't have a bike that is actually any better for riding around town.

The World Sport also went through a lot of changes, and ended up quite a decent bike by the late eighties. It started out as a high ten steel model that weighed a ton, with low grade components. Later models were CrMo steel, forged drops, and alloy wheels. At the midway point it had alloy wheels and CrMo tubing, but had stamped drops with an built in hanger, with a tacked on plate to make it look like forged.,,,,BD

How about a 1985, into a 2005, is that allowed? Why wouldn't it be any better for riding around town? This one sure the hell is? That wasn't a very constructive thing to say, IMHO.

under construction of course..

I've sold two of the mid level world sports this summer, both were similar to that teal one but with blue to silver fade. They seemed ok, stem mounted sis, 6 speed, araya alloy wheels. The dropouts had this strange feature in which they were "fake" horizontal. Meaning the drive side dropout was only half length, filled in with some metal. If you tried to turn one of those frames into a fixie you might find yourself without enough range to adjust for chain tension. Other than that they were mote than acceptable commuters.

Thanks all of you. So can I ask then why is it so bad that I want to get rid of a 10speed gear system and make a single gear? I do not know how to adjust these and re build gear systems so I thought i would get new rims, and then re build the bottom bracket. I could pop a chain on then be on my way?

Is this bad to do?

Also, I started to peel off the grips since they were pretty rotted foam. Underneath I see really ugly handlebars. Kinda of rusted and seems to look like two separate metals. Weird.

If you want a single speed put it in one gear and don't touch the shifters or just shorten the chain and take the shifters and derailleurs off. Then when you are sick of one gear in a couple of months you can put it back the way it was with very little effort and no cost. Roger

My parents bought me a WS as a high school graduation present in 1985. 2x6 with stem shifters and suicide brake levers. Loved that bike. I rode it all the way through college and law school, did a couple triathlons on it, commuted to my first job on it. I wish I still had it.

I'd probably make it into a SS or FG, but don't put too much money in it. I think it has a freewheel, rather than a freehub, so you can just spin on a bmx freewheel. You might get lucky with the chainline. Or not. But have fun!
