depends on how old that bike is and what size rims it came with. Schwinn made at least a couple of completely different Travelers. Don't know if the newer ones had 700 or 27" rims. Your brakes might not work with the wrong size rims.

Are your tires or rims labeled at all? They might give you a hint. Often the sidewall of the tire will be printed or engraved with its official diameter.

hokay good idea..i just checked and the front tire(which is new) says its a 700x28. So i assume that means the wheel is a 700c. Is it then safe to assume that the back rim is the same? If so will any 700c do the job?

Thanks..i know i sound stupid..i just never fixed or delt with bikes before.

Yeah, any wheel should do for an older bike. Especially with the bigger tyres; the lower-pressure used absorbs a lot of shock and enhances wheel-durability greatly. You can usually buy a basic quick-release 700c wheelset from bike-shops for about $100-150.

sorry for asking another question before the other is answered but...is it ok to have two diffrent size tires on a bike...

Like the front one being thicker then the back. At the moment i think thats the way my bike is set up.

It's fine. For a while I was running 700X28 on the front and 700X35 on the back. Mainly due to the fact that I was trying a new tire and wanted to make sure I liked it before buying another one. I think a wider rear tire may help in stability a bit. Just my guess. I'm sure sheldon brown has some thoughts on this.

Couple of things:

1. Rear wheels come in freehub and spin-on freewheel versions. Make sure that you get one to match what you have. If you don't have the tools you'll have to find somebody to switch out your rear cogs.

2. Try to find a wheel that closely matches the width of your rim. The "c" in 700c is supposed to be a width measure like in shoes, but they're not all the same width.

Oh man. I learn so much from things people call "Stupid Questions." I had no idea what the C in 700C meant.

It actually turns out to be a measure of diameter rather than width.

700mm is the theoretical diameter of the tire. Now, if you think of the tire cross section as roughly circular, with a wider tire you'd need a smaller diameter rim to keep the outer circumference constant. Consequently a 700d rim has a smaller diameter than a 700c rim. That's also why computer manufacturers suggest that you program in different factors for wider or narrower tires.
