Conti ultra sport kevlars are pretty much impossible to puncture when you cut the bead off them and put them under a Vittoria rubino

I had a nasty cut in the rubino and my conti was worn out so being the scrooge I am I fitted it as a liner, you can ride it at 80 psi and it's as hard as a one of the tyres would be at 120 psi, this is on my training bike where I don't care about fast tyres just want it to go for a long time without punctures and get a lot of km's out of the tyres.

Being close to the 3 digits on the scales means I wear and break things quicker than someone less gravity challenged.
