C-Hog said:Hutchinson Top Speed 700 x 28c. I have a set of Bontrager RaceLites on my Salsa cross bike (which doubles as my road bike) and these are what I use. I wouldn't go any narrower than 28c on that rim.
Also mtb frames tend to be pretty harsh with narrow high pressure tires. 28-42mm tires are nearly as fast and ride more smoothly.GlowBoy said:I've run 700x23c tires on 22-23mm 29" rims with zero problems. I've heard others say not to go quite so narrow ... you could limit yourself to tires of 28mm and up to be on the safe side. Or not.
Here's another thing to think about: the Maxxis WormDrive. It's 700x42 (really more like 700x40) and rolls as fast as most road tires I've tried (at least at the 75-80 max psi this tire is rated for). Not outrageously heavier either, at 440g or so. Just think, you can have pretty fast road performance and still be able to go offroad (within reason) with the same set of tires. Take that gravel road shortcut you've always dreamed of doing, but couldn't on your road bike.
Anything up to about 700x42-45 will fit in a BOB trailer without having to replace the front fork. Not sure about kid trailers though.atl-dad said:It's hard to believe more people don't go to 29's with all the tire choices available. I know a lot of mtb's don't see much serious of road use. I just bought a GF 292 so I'm hoping I don't run in to alot of the problems people talk about, but for the price it's hard not to get it. I can't wait to hit the trails and do some adventure and xterra races on it.
I think the 29 inch wheels will be nice too on the days I'm just out towing my two kids around town.
