First look of cheap TPU inner tubes bought on Aliexpress. I'll post a follow-up video to discuss durability AliExpress parts used: Cyclami TPU Inner Tube: s.click.aliexp... Carbon wheelset: s.click.aliexp...
I’m using both the Ridenow and the Offbondage brand of TPU inner tubes and so far I absolutely love them. The feel is subtle, acceleration is noticeably improved and the make the coolest resonating sound at speed. Just have to be careful especially on older rims the valve stem won’t fit the rim’s valve stem hole, so be aware of that possibly happening on rims that fit the 23c tires comfortably.
I've been using these tubes as spares for a while (ride now brand the pink ones). They're mostly very good just had 2 of them end up with slow leaks at the weld after a month or so. I'm going to try this brand soon looks like the price has been going down even lower and there's a couple other brands as well
I've got this, and the pirelli smartube...7€ vs 25€. The only difference is my wallet. Even Pirelli got leaks. 1 bar/week. Every friday i've got to pump 1 or 1.5 bar more.
