TPU Inner Tubes

[sasquatch16v]

I had horrible experiences with Tubolitos.

bought 2, 1 flatted immediately and the other one started leaking from the valve stem after 2 rides and wouldn't hold air.

Tubolito warrantied them both, one immediately started leaking from the valve... again, and the other started leaking air from where the valve is bonded to the tube.

The 3 rides I did on them they did feel nice, but like 70$ to last a total of maybe 50 miles. NOPE.

While binge purchasing a bunch of things on Ali Express I did impulse buy the ridenow tubes for 8$ each. The have been setup on my bike (not ridden because of winter) but holding air just fine. The way the valve is bonded to the tube seems more robust that the tubolito and the valve itself is a metal one like a standard tube, which is likely to be much more robust than the POS plastic valve on the Tubolitos.

I'm hopelessly optimistic about these, but if they're trash... they were 8$ each not 35$ each.
