29er wheels - fitting 700C tyres

[levett]

I believe that 29er MTB wheels are the same diameter as 700C (though obviously a wider 'section'. From a brief measurement, standard road bike 700C rims are about 17mm (inside to inside the rim) and a 29er wheel I measured (Bontrager) was about 23mm (inside to inside the rim).

 

Question: Can you fit something like a slick 700 x 37C or 700 x 48C road tyre to a 29er MTB rim?  (we did a quick 'trial fit', and it looked like a 37C tyre would fit fine).

It fits fine, I had a set of 25c road tires on my 29'er once, then took them off because it's evil and should never be done ever again. Don't do it I tell you, don't do it!

Don't worry about my sanity too much:

The idea:

A set of 29er wheels with proper manly knobblies on

and

A set of 29er wheels with 700C road tyres Conti 4000S in 700 25C on

 

JB made up a set of wheels for the wife's bike SLX hubs with 700C rims for her to use on the road, and they work very well - low rolling resistance, and help the gearing (slicks on a 26" wheel just reduce the rolling circumference, and make the gearing even lower)

 

The MTB hubs with the 700C rims work very well on a 26" mountain bike and, on her Scott, fit without any problems at all - used on the Tour Durban last weekend, and very successful.
