    1989 Schwinn WolrdSport Project

    --Disclaimer-- I also hate when the same ?s are in a new thread so feel free to link me in the right direction.


    Hey guys,

    I just bought a 1989 World Sport 48cm for my wife. I am wanting to get her into road riding. I have already spent a few hours using the search button looking for the info I need but no luck. I am new to bike building in general so I'm going to ask some dumb questions.

    What I am wanting to do is upgrade "slowly"

    The bike "as is" is ride-able. The cranks are not original , a mixed matched set of specialized components. 27 1-1/4 wheelset (non origional)with decent rubber on it. Original brakes and bars. The cassette is a 5 speed, but from what I'm reading on the specs it would have been originally a 6speed. Can anyone confirm?

    Basically I would like to come up with a parts list from the collective minds of the forum.

    My thought is to replace the 27" with 700c, if in combination with new brakes, will fit.
    I would also like to get her back to 6 speed with new cranks as well.

    ----dumb questions----

    Will buying new parts and putting them on this frame still leave me the option on finding a 47-49 ish road frame and transfering them? (little by little make a new bike)

    Where is the best place to find the original decals?

    Will 700c and new brakes fit this frame?

    Will a new crankset and bb fit in anything else?

    Lots of questions! Yes, most parts should be able to transfer to a better frame eventually. BB may or may not...depending..but SHOULD unless new one is Italian or French..700s SHould fit...depends on just which brakes. I did the 700 transfer on my old 79 Schwinn LeTour, it did just fine, getting rid of the old chrome, lost a couple pounds, more tire selections, and stops much better. On the freewheel, if you get one with HyperGlide, it will shift smoother, don't know just what you have, it may or may not be HG.

    This is correct, and it is most likely a freewheel rather than a cassette. The shifting on that bike should be indexed, so if you do replace the freewheel with a 6 speed, make sure whoever worked on the bike didn't also put 5 speed shifters on it.

    I really don't see a reason for doing this (unless someone put steel wheels on it, it should have alloy 27's).

    Unless the paint and decals are reeeeeally beat up, you're most likely better off leaving it the way it is.

    Yes, anything that uses the standard english threading.

    I think I've got a set. I bought them for a project a while ago and never did the project. And even if I did paint it, I don't care so much about the decals anymore. I'll take a pic and send it to you. I think they are more mid- than late-80s, but you might want them.


    If you're going to put a different freewheel on the bike, get a new one that has the ramped gears. It will make shifting easier.

    I have a '86 World Sport. The bottom bracket is English, you should not need to replace the crankset, just the freewheel. Any parts you use should be transferable to a different road frame. Here is mine, after the rebuild:

    So getting a 700c wheelset without a freewheel would be your suggestion?
    I know I want to replace the brakes. They appear to be warped. I will post pics of this bike tonight.

    Thats a really good looking ride!

    We'll talk when you get up to 50 posts. Don't worry, I don't gouge. I've pretty much decided I'm not gong to use them, so they are of no value to me. I need to check to see if I can find them.

    Thank you!

    It might take me a few days to get that many.

    I just finished reading sheldon's articles on DIY gearing for older bikes and spacing the frames.
    Not exactly sure if I think I will go to those ends yet(bending with boards and whatnot). I think getting her into Indexed shifting will be important.

    As of right now (looking at what the others posted and cleaning it last night.

    The bike has friction shifters, and a 5 speed freewheel. So either the friction shifter is for a 6 speed(original?) or not adjusted properly, it tries to jump over the largest gear if turned too far.

    So getting a 700 set that is a 126mm rear and putting a 6 speed back on, will I have to stay freewheel or can I use a cassette? Im going to have to replace both derailers and brakes, correct?


    Thanks again for the friendly response to the dumb questions. I am reading and learning so much everyday (way harder to get this info talking to most LBS employees)
