Built a front wheel with DT240 hub and 650B hookless rim

Another wheel day (and so on).

I built a front wheel with a DT240 hub and a 650B size carbon rim.
There's a warning sticker at the valve hole position that I often see on Chinese carbon rims,
and it says you can tension up to 130 kgf,
but based on the feel while building the wheel, that seems a bit questionable,
and since you can build a sufficiently stiff wheel without tensioning that much,
I didn't tension it all the way to the spec.

It's a hookless rim.

Latest DT240 disc hub, 28H, black half CX sprint.
Built in reverse Italian pattern with black aluminum nipples as the base,
only purple aluminum nipples on both sides of the valve hole.
I'll do the truing later.

This hub is for Cannondale's Lefty fork,
a wheel for their gravel bike, the Topstone.
In the image above, I've installed the one-key release cap which has reverse threads,

When building the wheel, I installed a dedicated adapter,
and the wheel center reference is based on the adapter.
