I think it's safe to say that RideNow tubes are among the most popular of all TPU tubes, not even just chiner tubes. When I go on Ali, though, they're all over the map. Different stem and valve styles. Different logos, different color combos. I know they legitimately made some changes, and I know that these companies are always changing things without any notice or documentation. That's just part of it. But, one that threw me today was that some of the boxes were different on the gravel tubes compared to the ones I bought a couple months ago. I've seen some of the different boxes before (some are clear, some are white) but now there was a third box style. There are just SO many sellers, so many different combos of stuff and prices are all over the place. Some of these just can't be legit, right? Are there chiner knock-offs of chiner knock-offs? Has anyone encountered ones they're sure weren't legit?
