VittoriaWettkampf-Latexschlauch – Performance Bike Tire Tube – Leichter Fahrradschlauch für Rennsport

They break easily where the valve glues to the tube. Bummer cos I love the road feel of latex tubes. You can’t fix that with a patch kit. I’m going back to Schwabe butyl tubes

Didn't even ride with them for over a week, (maybe just a few hours/16hr) and when i went to change to a new tire i noticed the valves were failing. I have been installing tubes for years and am very proficient at it (prior bike mechanic) i had to create my own repair to them by adding an adhesive because i don't have any extra tubes at the moment. What a bummer, very disappointed in such a well spoken about company.

Two tubes ruptured at around 60 psi around the stems. I wanted them to work so much, but they were a big waste. They inflated with a huge bulge near the seam, making a formerly true spinning tire wobble. The black stem looked sweet though- for the minute or so before all the air leaked out....

The picture shows a 29-in tube but the print shows 26-in tube. I thought it was ordering a 29 and received a 26 so I'm stuck with a useless tube. Have a nice day.
