Tubolito Tubo-BMX TPU Inner Tube 20", 22”, and 24” Wheel Sizes | Fits Tire Widths 1.5" - 2.5" and 1 1/8" - 1 3/8" | Schrader & Presta Valve Options | Compatible with Rim & Disc Brakes

The tubes I received did have Presta valves so that is probably what you'll get if you orders these. I prefer Presta valves. I installed the tubes on wheels for a 24" BMX Cruiser. They are a little harder to install than regular old inner-tubes but significantly and noticeably lighter. One confusing thing is that in the paperwork they came with it says it is OK to use these with rim brakes for a BMX bike, but then on the tube itself it says do not use with rim brakes. I guess they might explode if they heat up? That would suck. It would be nice if this was straightened out and made completely clear. If they explode I will update this review! That they are lighter, more puncture resistant and hold air for longer than regular old tubes so I am trying them out. Also just fyi, once you install them in one size tire you are not supposed to use them in any other size tires. I think they stretch to shape and may not be able to stretch back. What this means is that if you install one in a 24" by 2.1 tire, you should not later use it in a 24" by 1.75 or 2.35 tire.

Listing calls these a schrader valve, but they are presta valve. The picture is correct and matches the item if you look closely it says SV Presta. The title of the listing calls the item a Schrader valve.

Just deflated. Doesn't work
