29ers: a 700c wheel?

29er wheels all seem to be labeled as having a 700c or 700b rim, witch is standard on a road bike nowadays. but it seems like an older 27 inch road wheel is bigger. is it just the tire that makes the 700 a 29"?
Im really confused... any help would be great
thanks
-mike

It's a rim that is 700c in diameter, though of course 29er rims tend to be a bit wider than road rims.

yes, it is the profile of the tire that makes up the difference.

For actual mountain biking? Open Pro's are tough, but not exactly singletrack tough. Plus, narrow as the rims are, I'd be more concerned with pinch flats, especially if you're planning on using a high-volume tire.

Bottom line, I think that's screaming "Bad idea."

Road bikes use a 130mm rear hub width while moutain bikes use a 135mm rear hub width. Unless you have a frame meant to be used for both(such as some surly's) it would not be a good idea.

If you need a cheap set of wheels try this Bike 29 wheelset: Deore/WTB Dual Duty
