26" World Tour Schwinn?

[jeremy]

I'm trying to buy new rims for my old world tour Schwinn. I've been told it is both a 26" and a 27" bike. My question is' "how can I find out what the factory size is?". I also, want to find the same set that I have on it now. The front is an old design quick release and the rear is a (I'm guessing) standard set up. Can anyone help me.

Do you want to buy rims and lace them on your hubs, or do you want complete wheels. IMO easier option.There should be numbers stamped into the rim, look closely. It will say size.
If its an old bike these wheels should fit.

For the current wheelsize (as this seems to work) simply look at the tyres. They should be marked with a size information like 622-47 or somesuch. The first number is the bead seat diameter, the second the tyre width. The BSD is what you are interested in. Look at the lists at

and compare. The best (well, most sensible) wheel sets are "traditionally" made, that is, the spoke patterns we are all used to, most often 32 or 36 spokes that are laced "cross 3" (each spoke crosses three others). For reliability get custom hand built wheels or wheels that have been trued, tensioned and stress-relieved by somebody who knows what they are doing. These people should be able to basically build almost any combination of rim diameters and hub widths - though sometimes it could be costly as they might have to source parts that are not easily obtainable.

You could put either on it, but if you want what you've got now,just measure the rim with some measuring tape

There was a Schwinn World Tourist made quite a while ago, and a World Tour that is a more current bike. Need to know which you have for sure.

No, you can't "put either on it," and measuring the rim does not work either. If the current wheels fit correctly the tires will have on them the correct size.

[daniel1988]

Oh how comes you cant use either?I've got 26" wheels on my mountain bike,so if I brought 27" they would not fit you are saying?you can measure the diameter of the wheel with tape,if you take the tyres off?lol surely

[cny-man]

It might fit, but probably not, and the brakes might not be adjustable to reach the rim. Measuring the diameter of the rim does not tell you directly, as it will not measure 26 or 27 - that's the diameter of the tire. Again, the tire will have it's size right on it. http://sheldonbrown.com/tire-sizing.html

Okay thanks man, do you know if its possible to put 700c wheels on a mountain bike frame, I know the they fit them onto hybrid bikes,but presumably the frames are designed differently,thanks.

[cny-man]

Again, may or may not work, no single answer. It depends on the frame and brakes, but easily determined by trying out a 700c wheel.

[daniel1988]

Yeah I might do that thanks, what's the main difference between a hybrid frame and a non-suspension mountain/commuter bike,thanks.
