Is there a difference between 700c wheel and 29ers? Thanks. Sorry, I hate to create a new thread to get an answer to a possibly very simple question, but it's bugging the heck out of me. Thanks.

Rim width.

Marketing.

So there can be 26'' and even 20'' 700c wheels then? And there are 275.590551 inches in 700 centimeters, how dose that relate to width?

29er = really wide 700c. The 29er usually refers to tires with MTB treads. Tire conventions can be somewhat confusing.

Same circumference. Why they decided to call them 29" I don't know. They could just as easily have been called 700c mountain bike wheels/rims/tires.

So what is the width of 700c wheels?

Everything you ever wanted to know about tire sizing

The diameter is the same. The width is measured between the rim sidewalls (i.e. as a cross section)

A wide 700c and a narrow 29er would have the same dimensions.

Sheldon's blurb explains all.

MTB folks are American good 'ol boys and think in inches. We have George Bush and 26 inch wheels. Now, we have 29" wheels as well. Roadies are Euro-loving, tour Day France watching fools who have John Kerry and 700c wheels. Those, are really 622 (not 700). Plus, the c implies cm, but that would be huge. It should be m for mm.
Of course, GW is a liar too. His wheels are not really 26" and 29", they just grow to about that size with the appropriate size tire. GW is currently trying to get pi adjusted so that his cyclocross wheels can be 29er as well.
29er wheelsets and 700c wheelsets are the same diameter and have some overlap, but they are generally designed differently. 29ers will often be disc friendly or disc specific, they will generally be on mtb hubs, 135 spacing, beefier components, and so on.
Al Gore invented 32" wheelsets. They will be out in 50 years, if the earth is still cool enough.
Half of what I just typed is meaningless drivel. The other half may be, too.

here's my 700c street bike...

29'er is a strange number...
but everything else comes in metric sizes... cranks, seatpost, stem, handlebar clamp, fork end width, screws (M5, M6).
Honestly I can live with inches and gallons, but Fahrenheit, pounds and ounces confuse me to no end. Inches get confusing when they become decimals... 0.5in is easy enough, but what the hell is 1.9in? 48mm that's what...
"700c" is the spec. 622mm rim size and whatever tyre fits on it. 700c x 23c (23mm) is roughly 700mm tall... 700c x 35c (35mm) is about 730mm

Ehem. Shouldn't you have also posted that in French? I'm telling.

En Francais?
Not all Canadians speak French
But maybe I should have posted it in Italian, since they set a lot of standards. then again, English BB with imperial threads...

The bike is made with multi-national standards

The "c" does not refer to centimeters, it is a relic of the old tire sizing system. 700a, 700b, 700c.......

Hope this helps.
