Really happy with these TPU tubes. Lighter and comparable road feel to butyl. Love that I can patch them unlike latex. The included patch was easy to use and got me home safe!
The tubes are somewhat delicate but if your tire is robust you can run many miles with a problem. I've gone a whole season without a flat on these tubes.
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 doesn't 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.
If you are looking for a way to loose grams this is a very good option. They are also really good to carry on a jersey pocket.
Tube failed where the valve stem meets the tube and it happened after just a half dozen or so rides. Very disappointing for such an expensive tube.
Straightforward to install ' no issues whatsoever. Have not performed any rolling resistance tests, but no complaints from usage. Comparative cost (to butyl and latex) is the only negative.
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.
