hook.
Please find as below. It is our design for the new mountain bike 26 inch rim.

To make the tubeless 26er hookless rim stronger, we did the creative attempt—removed the bead hook. This design
makes the 26er hookless rim stronger and less susceptible to damage when riders smash into rocks on the trail or
land awkwardly off a jump.
With the hook gone, engineers set out to tighten the seal between rim and tire. It's very necessary because the
sealant had less material to cling to, making it easier for air to escape.
The fix is simple but effective: the new rim has a wider inner shoulder, which gives the tire's bead more surface
area to seal against. There's also a more robust rim strip that prevents sealant from leaking through the rim's
spoke holes.
Without the hook, we were also able to thicken the rim wall, making it even stronger. It also means that one
potential weakness is removed. Together, these improvements keep the tire from blowing off the rim once it's
inflated.
All your suggestions are helpfull for us to make the rim good enough for mountain bike downhill and AM wheels.
