The thing I like best about these tubes is the air nozzle is completely threaded and includes a ring that seats against the wheel face, making it easy to fill. I ride a lot of miles every week, and it is inevitable in this area to pick up a sand burr, especially in August. All tubes must have seams because of manufacturing processes which can be a hindrance to a patch repair, but these tubes don't seem to cause problems in that area. I am very glad that I discovered these tubes.
My E-bike came with with wheels drilled for the schrader valve tubes, and rather use adapter after reading another rating for the new style threaded stem, I tried a set and highly recommend them. Good job Continental !!!
I ride 7miles to work each way, every day, rain or shine, on paved shoulders full of debris and on grass, after sunset and before dawn: These Continental tubes with Michelin tires endure best, from my experience. Great customer service helps a lot to get ready. Thanks!
Continental tires are the top of the line. The Shrader valve is valuable to me because it has a restraining nut that prevents damage when you inflate the tire.
Excellent tubes. Love the new style schrader valves that have the presta style rim nut. Will buy these again.
