Review on Kenda 29er Bike Tube 29x2.0/2.4 (48mm Presta R/V) - Pack of 4 with Decal/Sticker by John Stowers

I bought 4 packs of inner tubes, not to save, but to have it more conveniently. Well, extras were needed as 3 out of 4 are broken so far. They all leak at the seams, even from the tread side of the tire. I've changed a lot of bike tubes/tires in my time, so I know it's not a fit issue, and neither are these bruises. All flow a bit slow at the seams. By the time I got around to using them I must have passed the return window, but these things shouldn't be sold anywhere at any price. Totally useless. Do yourself a favor and stay away.
