Kenda Butyl Tube
The Kenda Butyl Tube is the the perfect tube for a perfect ride. With a wall thickness of .85mm and valve lengths of 35mm Schrader or 60mm Presta, all your bases are covered.
Have bought a number of these (26") and have yet to have an issue. Just your typical run of the mill tube, nothing special.
I bought these to replace tubes for my mountain bike. Do not waste your money. Out of the box the tube had a hole in it! I would return but I have to pay for shipping.
