try to give the big brands a mail, iff you get a answer in a month you are lucky.
my experience with the Chinese brands are realy good when it goes about reply the mail, bad experience with delivery times.

Using the RideNow tubes on my race bike for over 1000km now combined with Conti GP5000. I installed them as I do with butyl tubes...
Rolling great no problems, rolling well. However you need to check the air pressure more frequently.
They seem to loose more air than butyl but still way less than Latex.

I also have them as reserve tubes on all my bikes including the gravel due to space and weight savings.

What is the point of buying wheeltop edx while a GX AXS is cheaper and proven?
Or is the quality of wheeltop more on the same level as XX1 groupset?

Can someone send me an aliexpress link to stores selling legit YBN 11 speed chains please.

I recently bought a shimano 11s chain as a backup from Ali and am only now realizing it’s a fake. I bought it from “preference cycling store” who had pretty good reviews for the chain but looks like the people reviewing it are not able to tell. The key giveaways were that the check mark at the front of the box on the bottom is printed (should be done by hand) and the quick link is in the same package as the chain (should be separate). I’ve read some good stuff about YBN chains, so I think I will give that a try instead

It is one of the superdeals at the moment. I also buy in USD and let the creditcard  company do the conversion. That's cheaper than buying in EUR from Ali
