The supersonic tubes have worked great so far. They cut my tube weight in half. Have about a hundred miles on current set with no issues. Guess it depends on the roads you ride too. I have country roads that are fairly clean.
about 4000 miles with supersonics on the MTB with Panaracer Cinders, again no punctures
My theory is they are so supple they deform around sharp objects., I have no regrets in losing 50g per wheel!
Also you can fit 2 supersonic spares in the space and weight of one normal spare

just get the cables, not the outer, also get a length of the liner, it's cheaper that way
then get a nokon kit, use the powercordz liner throughout, *not* the nokon one
as long as you install correctly and do not nick the cables you'll get a few years out of them, they dont stretch at all - once the nokon etc. has snugged in - which takes several rides, so it's important to start with high tension and leave a loop of cord so you can pull more through and reclamp if necessary - but the shifting/braking is *much* better than with the gore ride on
if you need to change front/rear mech it's not advisable to use powercordz as once clamped the outer is squished and may strip if you try to refit
I'm thinking perhaps the 75g Michelin Aircomp ultralight at $9 USD might be a good compromise. Thanks.
I must admit, however, that the prospect of 13lbs bike is now in my mind. If I switch the brakes, expander, housing, cables, and tires I will be around 13.24. Definitely something to think about.
I tried to post a pic for you all but the forum won't load more than 160kb and my camera won't take anything smaller than about 165. Sorry.
Thanks again for your help!
I also received my Conti SS. I was surprised at how thin they are. I had to wear my sunglasses while pumping them as I was afraid they might blow up on me I put 120psi in them as a stress test and so far so good. Thanks to all for the input.
