Duro Bicycle Tube 29 x 1.95/2.25 (48mm) Standard American/Valve

very good

i like that these tubes have grit coating giving the impression that they have an extra layer of defense.these tubes installed can last me a full year as long as i have a good protective tire like continental mountain king,the only times i got flats where when i dident change an old balding tires and punctures starting to get thrue,butno punctures with new tires,a little pricey but i buy these because a bike shop held these making me wonder why they were so expensive and it is because this is a good quality product that is worth buying,

Tube had a leak from the seam(I guess that's the name). Not steam, but where the rubber goes together.... it wasn't together properly.Really upset about it. Story too long as to why this was at the wrong time and place.

After some months of use I needed to change my tires and when I inflated again after mounting the new tire the base at the tube valve blew up, it couldn't handle the pressure. This is not normal, it's a low quality item, I won't buy this brand again.

Tube has a 48mm presta valve.

Not the valve stem pictured, the ones I received are standard length and I need the one that is longer like the picture. Very disappointing the valve stem is like any regular bike tire.
