After about 200 miles on these, one of the tubes developed an unrepairable leak at the valve stem insert. Love the compact size of the tubes but with this limited sample size, it just doesnï¿½t seem the reliability is there yet. Wanted to love these but disappointed.
The Vittoria Ultra-Light Speed Road Tube is lightweight, tough and durable. The 60 mm stem length works well with aero profile wheelsets. An important feature for me is that it can accommodate the Quarq tyrewiz pressure sensor without leaks! I have 300 miles and counting without leaks so far. From my experience, this tube outperforms latex.
The small size and light weight are ideal and the reason for my purchase. Perfect for my emergency tube for my tubeless tires.
Sidewall puncture today that did not seal. Put a Gorilla tape boot over the puncture and installed the tube. Pumped up the tire with a Lezyne pump and continued the ride. Got home to replace the tire and could not deflate it all the way. Removed the core from the tube, still not deflated. Had to puncture the tire????.
I removed the tube and checked it for leaks. Air streaming out at the seam/weld. It had inflated the tubeless tire as the air leaked out of the tube. Forturnately my tape boot was air tight. Very expensive for a tube that doesn't hold air on the first use.
