Hi, I discovered your site a number of weeks ago and have ploughed through all the posts and comments quietly. I decided to might post my firstcomment. Not really sure what to comment but anyway. Informative blog. Will visit soon to see what else you have to offer.

I see no reason to pay the ridiculous price for these rims especially since you can’t build them 3 cross, or run tubeless. Stans Flows run tubeless would end up lighter and give a much wider tire footprint with less pressure and more compliance. At $85 per rim as opposed to $850 per rim I would rather have the Flows if the price was the same.

kaz_kougar: First of all, yes, you can run narrow 700c rubber on 29″er rims. Here’s the detailed answer…………..

Many 29″er rims are sub 28mm wide, some as narrow as road rims are at 23mm, or even 20m wide. The narrower the rim, the less problems you will incur by running narrow tires in the 23mm to 30mm range. In fact, I wouldn’t recommend using these narrow sizes with anything wider than 24mm rims. Why? Because as the rims get wider, they by necessity spread the beads of the tire further apart, taking the tires shape in profile from a nice arched “U” shape to a flattened profile. This will decrease the height of the casing in relation ship to the rim walls, allowing for easier pinch flatting and bead blow offs.

If the rims in question are 24mm to 28mm wide, then a minimum tire size of 30-32mm would be pushing your luck. I’d not do it, but would opt rather for 35mm rubber and up here.

28mm plus? I wouldn’t consider anything under 35mm as even being a posibility, and would rather stay above 35mm, especially at or above 30mm rim width.

So you see, you can use narrow roadie tires, with the caveat that your rim width and diameter must be compatible with the tires you have in mind. As long as that is in place, it doesn’t matter what the nomenclature is.

Okay, I’ve gotten mixed answers on this, not sure if this is the appropriate place or time to ask but here goes..

Shopping for a new commuter, considering a 29er. Can I run 700c tires on a 29er? I’ve heard several people say yes, as long as they are wide enough. My understanding is that the rims on a 29er are the same diameter as a 700c wheel just wider. A guy at my LBS told me today that you can’t run 700c tires on a 29er at all. I’m sure I’ll get a few, “Why would you want to” answers on this which I see as beside the point but I guess my answer to that would be for increased speed which begs the question what do I stand to gain in speed assuming I could go to a more narrow 700c wheel? Your comments are always appreciated.
