Am finding that when I buy used bike wheels on Ebay with tires on they usually have valve stems that are too short so needed to upgrade several of my bikes and bought a second round of nice continental tubes with longer stems so problem fixed and on with getting out and riding.

I received the item promptly and everything was well packaged. The only problem was that one of the tubes was defective. The defect appeared that it was too fat around the valve are and as a result, the tire would not properly sit in the rim, without creating a bulge. Other than that, the two other tubes were great. I've never had this problem before with the hundreds of tubes that I've gone through in my lifetime.

You can't beat these for the price. They're a bit heavy for a "racing" tube but seen to hold up better than lesser well known brands, especially at the valve junction.

Difficult to wax poetic about an inner tube... with that said, this product has worked well for me and they are a very good buy on line from various sellers. Good brand, good product, and the valves work well. What more can a cyclist ask?

Continental tires and tubes are high quality, long lasting. I have tubes 5-7 years old that still perform great. I put new ones on my bike every spring. The used ones keep piling up. they still are 100%
