Easton rl90 are a better rim with improved tubeless compatibility over the hed rims
Tubeless compatibility is kot just about seat and sealing the tyre. The tyre has to remain seated without air. Once setup and come sealant refill time or a flat I have not found the hed rims reliably hold onto the tyre or if the they do the retention seem weak so even I serting a plug causes it to unseat. That to me is not tubeless compatible. The issue is with an alloy rim at this price everything should be spot on.
HED and DT swiss lack a bump next to the channel to keep the tyre seated. Kinlin dont use a bump but a rise to the central channel which does the same thing, keeps the tyres seated.
Mavic ust rims have the bump. Pacenti dont but tyres stay seated.
Hed and dt swiss rims rely on the gluing effect of the sealant and tyre bead friction alone but this is not that relaible.
This is not my opinion it is how these rims are. Yet the manufacturers.swear blind that they are tubeless compatible which also.means they dont understand tubeless compatibility. Hed and dt swiss rims do not meet the new retro road tubeless standard that also a fact.
a few months ago, when you stocked HED Belgium Plus rims.... they were the best (you stated that on this forum) .... then a few months later, you had a rant saying that HED would not give you the rims at a discount price to sell on to the public (it's here on this forum) .....
then, soon after that, you started saying that the HED Belgium Plus were crap and that the tyres fall off when you get a puncture because they don't have an extra raised section, and you started pushing your Kinlins and others which you stock
OK, lets get things straight ...
No one has ever complained on any forum or the internet about tyres falling off HED Belgium Plus rims when they get a flat .... if someone has crashed or got injured due to this, please supply the link
look at the reviews about tubeless tyres being nearly imposible to mount on tubeless rims ... it's not the tyres, it's the rims and the rim tape ... whats the point of buying tyres, and you cannot fit them easily? ....
have a puncture on the road where the tubeless sealant does not sort it and you cannot remove the tyre or refit it?... this is what puts people off trying tubeless ... 7you end up phoning momma to come fetch you as you are stranded
thats why some rims are named as tubeless compatable or tubeless easy .... HED even has new rim tape where only 1 layer of tape is required .... tyres fit by hand and your IRC tubeless tyre levers are not required ....(they are very good though)
so, .... I'm riding along with my HED Belgium Plus rims and my Continental GP5000 TL 32mm tyres .... I get a puncture.... sealant squirts out and the sealant does not seal the puncture .... all the sealant squirts out and my tyre is completely flat and the beads pop out
what now? .... 2 options .... either I plug the hole with a dynaplug (I see that you still use worms, but that's so yesterday .... you need dynaplugs) and then add an inner tube, (If I am going to add an innertub, I don't even have to plug the hole) .... or I add more sealant, plug the hole and inflate with a CO2 25g Lenzye Control drive with the valve at the 12 O'clock position .... I dont faff with a micro pump .... it will not work, no matter how many times I furiously pump... if I have to add an inner tube, no loss, as if I had clinchers, I would have to do that anyway
I use Orange regular sealant and it does not interfere with the CO2.... even if it does, I can ride thousands of miles before the next puncture. With one layer of the new HED tape, I don't even need sealant as the tyre is totally sealed when pumped up
so, now you will say that yes, it's dangerous if you are riding and loose all the air and the tyre unseats ..... even if the tyre is still seated and you get a big gash and loose all the air instantly, you are in danger .... the exact same danger if the tyre unseats
so, stop stressing and criticizing HED Belgium Plus rims (you do that often, and I'm starting to get the impression that you dislike the company or someone who works there?) ....
and don't stock too many of your other hard to fit tyre rims in your shop as rumour has it that Continental will be involved in 2020 to set the standards as regards tubeless rims ... and from what Ihave heard, HED Belgium Plus are on the list ... so start stocking them
Here's an interesting article:

you need to take a step back and re-evaluate how to use tubeless tyres .... things and times have changed ...
there's a saying .... If you use yesterday's technology today, you will be out of business tomorow
