Zol Mountain Bike MTB Bicycle Inner Tube 29" x1.95/2.125 Presta Valve 48mm

Product has worked well and was delivered on time.

I bought 4 of these and 1 was a bust (see pic).The other 3 stayed inflated and performed well.

Let's face it, inner tubes are not exciting or fancy. They add no bling to your ride. You want them to hold air reliably and you don't want to pay a bunch of money to get it done (you want to spend money on bling!).Get these. the price is right, they hold air. Done.

I bought a two-pack. One tube lasted 24 hours with only 15 minutes of actual use. The other lasted four days after 15 minutes of use each of the four days. There was nothing in the tire or on the rim causing the defect. So, I guess it is each tube that lacks durability.I will be looking for a better choice.

I think it worked.. I had to replace it however.. One ride and things went south..

A good quality product. Recommended

Wont get again. Already gone flat since Christmas. Can't return as I took the tire to a bike shop and had them replace the tube with a heavier one and forgot to ask for this one back.

Product was exactly as described and arrived on time.
