2 Pcs 29 Inch Bike Tubes 29x1.9/2.3 AV33mm Schrader Valve Compatible with 29x1.9/1.95/2.0/2.125/2.3 Mountain Bike Tire

Mask is great, the tubes not so much. Popped on the first day out. I run tube protectors between the tube and tire. No gashes, thorns, or any othe visble signs. I was on a single track course and hit 3-4 ft of air and it popped. Luckily there was a different tube on the front because I could easily ended up in a tree after landing.Maybe it was a bad tube and I was unlucky... For the price, I might buy another just to test it again.

Not my first experience with this tube, but my first with this seller. I had a blow out while inflating the 1st of the 2 tubes. The seller more than made it right. Very impressed.

So far these are great. I am a really big guy so I have to run my tires at pretty high pressure. I lost two of the Slime inner-tubes in a row before ordering these because they blew out after a couple of miles. The face scarf thing they included is pretty nice for a free thing.

The innertube looks and feels high quality. I use it in my exercise routines. It was well packaged and there was a neck tibe/balaclava/bandanna type fabric with cool looking green scull on it😉. I would order it just for that bandanna 😂. Overall good delivery and packaging. Quality looking tubes.

I had to return because the valve stem was not long enough for my particular bike rims.

Perfect fit

Perfect... Just as expected!

As to be expected. Great brand. I.ordered wrong one they were great about letting me return
