On the tube deal: I haven't yet tried the Vred's, (can ya believe it!?) but I'm going to. I've been running the Vitt UltraLite's for the past 1 1/2 years and they've been great until I put on my new Zondas. All of a sudden, I started getting the valves pulling out from the tube AND the valve pins leaked air!!!
Probably because the Vitt's valves are only 36mm, and the Z's rims are 30, I dunno - it's hard to get a grip on them with the air chuck. I probably damaged the valves somehow along the way.(?) I didn't have any of the long valve numbers because I was using box rims before the Z's. Tried to get away with it for awhile, but "Yeah RIGHT"!
Anyway, went to the LBS and picked up my
other choice - the Specialized lightweight 48mm valves. So far, no sweat, but it's going to take some miles on these wheels before I can yelp too much about these tubes, because they're thinner than the Vitt's: 25-23c .7 or .8 Vitt's vs. 18-23 .6 Spec's.
The Spec's have always done me right in the past, just like the Vitt's have. But before a puncture can get to the tubes they gotta go through the tire somewhere. That's why I like the Vred tires so much. If you have good rim strips and run the right air, you've got no worries there.

Like I said somewhere else (?), I use only the Campo, Fortezza Road, or Fortezza Tri-Comp. All 3 have the exact same casing & excellent rubber compound, (except as U know the Tri's have the harder rubber in the center). For the price I'm paying there's no reason to go to the Volante, Ricorso, Flex Sport, or Spider Extreme just to save a few buck$. Those last 4 models might be the ones you're hearing mixed reviews about? I've heard generally good things about ALL of the Vred's, except I know the Flex and Spider are a bit on the heavy side.
As always - YMMV!
