Actually, it was an old idea that they were toying with.

They wondered about drilling Schader and then installing a rubber grommet that would down size to presta; Pull the grommet to run schrader or leave it in the run presta.

What intrigued me was the idea that the grommet also protected the presta valve from being cut by the rim (from repeated pumping). It could also help seal the rim a bit better from water but that was a minor point.

We suggested just drilling presta but I think part of the drive here, in their minds, was differentiation. They ticked all the boxes in terms of shape, tubeless ready, hookless etc, and they can compete on price, but I think they were trying to find a way to add some other feature that would differentiate them from their competitors.

So, a poll. And some other research. And we drilled a rim, found a grommet and started playing with the setup.

At the the end of the day, we will talk them out of it, but I need to be able to tell them why.
