The Bontrager std. tubes I run in the paramount ((700x18-25)run 98 grms.
The Specialized I was interested in were the light weight long valve ones.
I have to admit it. I never gave much thought to all the hoopla about lightweight tubes untill I spent a week with the 98grm bontragers (threaded stem) on the CF motobecane. The Kendas that came with the wheelsets are the lightweight jobs (blue stripe red cap)and I simply was hoping to check out the specialized vs other brands.
Specialized never mentioned I could order thru them (huh!) but at $10 a pop (plus shipping)I'd have passed.

Suppose now would be as good a time as any to get a cross section of what you folks run on your road bikes?(especially tube wise)
This has been a wet season up here in the northeast and the road hash has been really bad.
Any day after a decent rain I usually run the Paramount with the vittoria rubino pros. They definitely are sturdier than the kenda kalientes. I've got about 800 miles on the kalientes (sence new) and they're letting everything in but the kitchen sink.
They are a light fast tire tho and the payback is a ride that requires a hell of a lot less energy expended (over a 50+ mile ride -especially in windy conditions). I suspect the stiffness of the CF bb plays a large part along with the lightweight wheelset.
