Mavic Crossroc 29er wheel compatible with high pressure skinny ROAD bike tires?

If I try to mount a skinny (or medium width) high pressure road bike tire on a Mavic Crossroc 29er mountain bike wheel, will the tire blow off the rim when pumped up? I need a rear wheel that a) is disc brake compatible, b) has a 135mm OLD, c) uses an ordinary quick release skewer, and d) is 700C diameter. But unlike most riders, I want to use this rear wheel on a road bike with road bike tires. Not low pressure fat mountain bike tires.

Will the Mavic mountain bike wheels work for my purposes?

Thanks in advance, and safe riding,
Joel Dickman

Yeah, you should have no issues running a road tire down to 700c x 25. Just keep the pressure below 100psi. I have Mavic C29ssmax wheels running a 700c x 33 Cyclocross tire tubed at 80psi and it's great for 25-50 mile commutes!

Internal width of rim? Tire size? You should be able to use as small as say, 30-35 mm.

Thanks for the replies. I guess that there are two potential problems with my idea: a) The internal width of the rim is 19mm, as compared to 14 or 15mm on a skinny road rim. Use a 23 or 25mm road tire on a 19mm internal width rim and you increase the chance of pinch flats. But a medium width tire - say 28mm or a bit larger - might be OK. b) Mavic suggests using tires inflated from 30 to 60 psi. So if I inflate my tire to 80 or 100 psi there is some risk of rim failure.

I am going to try it out. The possible pinch flat problem does not worry me so much. It is the thought of the rim exploding from being used at pressures beyond its design limits that is more serious.

Is doing this bone-headed?

Thanks again,
Joel Dickman
