Review on Continental Presta Valve Black 25 32Cc by James Rogers

I ride a bike with wider training tires, typically 25-35 miles per ride. Having an apartment on every trip is frustrating, but road hazards are usually the culprits. Changing a tire on the road can be dangerous. For this reason I use vinyl liners to minimize flat surfaces of nails, spikes, etc. However, the last three of these tubes came loose at the seam. All within +/- 10 miles. The description says there is no seam. However, there is a seam and 3 not along the seam.
