  • A must buy!!!
Color: 20x1.5-2.1/ 2 Pack
When these arrived, I was extremely concerned with fitment, because my plan was to install these in my Schwalbe tires on my BMX Touring bike. I followed the instructions exactly, pumped them slowly to spec, and... they're perfect!!!! Extremely lightweight and noticeable difference not just in weight, but in rotational mass. You can literally feel the difference. I'm definitely ordering more, for my planned bikepacking trip. I've had these for a few weeks now, and have zero complaints. ... show more

  • Light, affordable, and pretty sturdy.
Color: 20x1.5-2.1/ 2 Pack
Our “go to” for BMX racing tubes. Light, affordable, and surprisingly durable. Recommend being gentle with the valve end; it is delicate.

  • Not strong enough
Color: 20x1.5-2.1/ 2 Pack
My son races, BMX bikes, and we were running this tube because of the weight. Unfortunately, I believe I purchased eight of them in a year time due to pinhole punctures in the tube, but never in the tread area, but down by the rim tape. It would always cause a slow leak where you would lose 10 psi in a 24 to 48 hour span when racing BMX bikes expert level, you cannot have a tube that leaks. So good price, very light, but easy to puncture. ... show more

  • Lightweight tubes for commuting
Color: 20x1.5-2.1/ 1 Pack
Surprisingly lightweight for the price, the TPU inner tube allows the front of my bicycle to feel nearly weightless while lifting it and the generous sizing allowed me use a 20x2.15” tire. It also comes with a sticker.

  • Lightweight, but valve stem is plastic and BREAKS!
Color: 29X1.9-2.5/ 2 Pack
Bought this as a lightweight tube to carry in my camelback while MTBing. Got a flat. Tried using this tube, but unfortunately the valve stem is made of plastic and broke - easy to do when you connect your pump and inadvertently torque it a bit (as I did). Fortunately for me I was with a group and somebody else also had an inner tube for me. Otherwise it would have been a long hike-a-bike back to camp. Would skip this product and pick one out that has metal valve stems that won't break on you. ... show more

  • Not worth it
Color: 20x1.5-2.1/ 1 Pack
Super light inner tube but not worth it, it bubble at the junction and started leaking air.
