The latex vs. butyl tube debate has gone on for years. Latex is lighter and has a better ride quality while butyl is heavier and less expensive. Beyond that, latex is un-patchable and cannot be serviced. Some riders would not dream of spending somewhere just south of 20 dollars for a tube, while others consider it a great value to shave a few grams and improve ride quality. It all comes down to your perspective.
The seamless and pink Vittoria latex tube weighs in at a feathery 74 grams. The valve stem measures in at 51mm length and features a removable valve core. The removable core which can be replaced if damaged or substituted with a longer valve for aero rims. This is the same tube used in the Vittoria Corsa tubular tire.
I put a pair of these tubes through the wringer over the past 6 months. I put them on my old Mavic Carbones with a set of Michelin Pro3 tires. I have been going between a wide rim wheel set with standard butyl tubes and my much narrower Mavics with the latex tubes and I really think the latex tubes lower the rolling resistance and improve ride quality to an extent similar to having wider rims. I think latex tubes in a wide rim would be the creme de la creme! Ive taken this wheel tire-tube combination down all sorts of terrible roads, gravel roads, city streets, and have not had a single flat in 2K miles! Now, I cant say for sure that my luck with flats is due entirely to the latex, but I can say with confidence that they do not appear more vulnerable to flats then any butyl tubes Ive used in 20 years of cycling. When mounting use talc for ease of movement and plastic levers only. They cant be patched but Vitorria pit stop should seal them. Ride with a butyl tube as your spare.
Pros: Amazing light weight, buttery smooth ride, durable
Cons: Tough to mount, cant patch them.
