Hi all: I've got a couple of gear questions I'm hoping someone can help me

with. I've been using Mavic Open Pro rims laced to Centaur hubs on my

cyclo-cross bike. The cassette is a 13-29. Today on a whim I mounted road

tires on the wheels and tried them out on my road bike. First thing I

noticed is that my tires, new Vittoria Open Corsa Evo CXs, mounted much

easier on the Mavic rims then on the Campy Protons I normally have on my

road bike. First question: Does easy mounting correspond with increased

chances of the tire coming off the rim at an inopportune time (like coming

down a hill). Second question: My Chorus short cage derailleur handled the

29 tooth cog just fine even though Campy seems to say it shouldn't. Has

anyone had any experience with this and am I jeopardizing the derailleur in

any way. I can't imagine being in the 29 to much but I'm trying to "be like

Lance" and spin up some hills. Thanks in advance for your info. Dan
