KendaRoad Bicycle Tube Bundle - 700 x 28/35 (27x1-1/8, 1-1/4) - Presta Valve - Four (4) Pack (48mm PV)

Very pleased with the quality and performance thus far.

They work as expected, no surprises.

These are good tubes! I was purchasing off brand tubes to save a few $$ but wasn’t worth it in the end due constantly getting flats. The Kenda tubes are much better and are worth paying a little extra.

I use these for my gravel bike. Weight is not really an issue when it comes to my gravel bike and these do the job fine. In fact, they are not really that much heavier than the expensive brands.

The tubes work great with my air pump, but not so well with the CO2. The air has held going on two weeks now after using my floor pump to pump it up. But when I used my CO2 to initially pump it up after I caught a flat with another brand of tubes, the air leaked out within 24 hours.

I bought these about six months ago and just got my first flat, so so far, they seem to have reasonable robustness.If you're using a CO2 cartridge for flat repair on the road, make sure that you use a tube like this that has non-removable valves because otherwise the valve will freeze to your CO2 cartridge and come out when you unscrew it and your tire will deflate in a sploosh, leaving you stranded.

I can't remember the brand I ordered last time, but had a series of blow-outs and valve breakages and had to change tubes more frequently than anyone would have wanted. I have not had a problem with these yet. They are heavier gauge than some but I think that the extra few grams are worth the aggravation.

Still using the original 2 tubes with my bike. They work great, and the long valve stems will work for deeper wheels.
