Great product

Seems like a standard quality tube.

I installed these on my Catrike recumbent trike running 20x1.95 Maxxis Hookwroms at 90psi and they seem to work fine so far. I replaced a Schwalbe tube which felt noticeably thicker, but these tubes hold the pressure and seem to be fine - for half the price. We'll see how they hold up long term, but so far I'm pleased.

Ok…. I thought it was going to be easy to install and I was very humbled and had to take to bike shop. Good news is they didn’t charge me since I already had the tube and it was easy for them to quickly turn it around. son was back on his bmx bike with min 24 hours of delivery!

They are tubes that held air well in my tires. What else can I say. Used in Schwalbe Triker tires on a Trident trike.

Exactly what I ordered

Product arrived in a timely manner & in great condition. Worked well. Thank you.

They are cheap, but my tire is already flat again. Bummer.

Seem to be good quality

Je gonfle a 58psi sans problème

price is quite good for these tubes , tubes them selves are good too.

As I understand, a lot of people who order tubes fail to distinguish between Presta valves and Schrader valves. Automobile tires all use Schrader valves. The Presta valve is much skinnier. Some purchasers have ordered tubes thinking that they will get the valves they want without understanding the difference. I ordered tubes with Presta because that is just what I needed. I was a little fearful that the wrong type might be sent. However, I got exactly what I ordered. Thank you.
