ContinentalBike Tube (26"/27.5"/29"/700)

Great quality and the valve stem threaded all the way is a nice touch for installing.

I purchased one tube for my MTB and it looks very strong and high quality, it's not heavy like some other brands and it has a plastic cover for the valve. I recommend.

My Salsa Vaya was built with Continental tires, at a shop in Saint Louis. These may not be easy to find at some shops in California. I've been using Continental tubes since Big Shark, have never had trouble with the tubes.Notwithstanding goat's head thorns off the road, assorted debris at odd lengths on the road, and the lifetime and limitations of a tire, the Conti tubes have held together pretty well I think. They also hold a patch well, when a puncture's not too much.I've used these with Slime in the tubes. I think it helps for the smaller punctures. Although it gums up the valve stem ordinarily, of course that's easily cleared with the Presta valves.For the next bout of debris at the odd corner after some new detour, I think I'll try looking for tire liners next ..

I bought two of these Continental bike tubes to replace the Schwalbe ones I purchased a couple of years ago. I kept on getting slow leaks around the base where the valve stem meets the rubber with my old tubes. These new ones appear to have an extra layer of rubber around that area which is something none of my older tubes had. I would recommend the Continental bike tubes to anyone looking for a quality product at a great price.

Muchas gracias!
