I'd like to build a set of wheels with the new Iron Cross rim (http://www.notubes.com/Iron-Cross-C127.aspx). I'm attracted to this rim due to its combination of low weight and intermediate width, as I'm building a weight-conscious disk brake "mixed terrain" (road + fire trail) endurance bike (http://www.kickstarter.com/projects/874048428/the-viaje-bicycle-engineered-for-adventure), and like to run an intermediate range of tires, whether smooth or knobby. I would almost always run with tubes, rarely tubeless.
The Iron Cross product description states:
"The new ZTR Iron Cross disc rims are designed only for use with cyclocross tubeless tires and traditional cyclocross clinchers."
Do folks have a sense if this is actually a question of, say, minimum tire size, maximum tire pressure, or perhaps some combination of the two? What are the risks -- the bead coming unseated? Radial compression of the rim due to high pressure?
What it really comes down to for me is that I would like to be able to run road tires as "small" as 700x28, and other times run 700x35 cross tires -- or sometimes even wider. Can the Iron Cross still be the rim for me?
Thanks for your advice!
