Sunlite Thorn Resistant Presta Valve 27.5x2.10-2.35 PV 48mm 0d

The tube does what it says. The problem I have had now twice is that the valve stem tore out of the tube. I didn’t tighten it down either; just barely finger tight. So back to the basic tubes and patches.;

Good way to clean up my old bike good so far after a couple rides;

Sunlite thorn proof tubes really last will not burst under heavy use. I value these tubes over others because they hold up under high weight and rough riding. They don't burst. I have never had a flat from thorn or burst on these tubes. The Sunlite tubes replaced a dozen prior tubes that usually burst from hard use. Invest in these tubes. They cost more but they are worth it.;

Felt like I was installing a garden hose on my bike. I would assume they're very durable. Gave up after 15 minutes. Returned to Amazon;

I had previously used Sunlite with excellent results. I was only able to get 1 in the size I needed for my new bike so I also bought another brand of their thorn resistant inner tube. On my first ride the Sunlite was still full of pressure but the other brand was flat. I will stick with Sunlite!;
