The Vittoria Latex tube is a performance inner tube, best paired with supple performance clincher. I like the fact that there is no seam. You will need to add air before each ride, but that is a small inconvenience compared to the improved feel and performance achieved with this latex tube.
I bought the Continental 1.752.5 MTB 26 tubes with the Presta valves to install with my Michelin Country Rock 26 1.75 tires that I bought at WesternBikeWorks. I store my bike in my home, but I haven't had to add air in the tires for 3 weeks and the pressure is still the same. With my old tubes, I had to add air weekly. These tubes have exceeded my expectations. Will buy again!
Reliable quality and competitively priced. They last and last but replacement is eventually necessary. It's not if but when.
