Another wonderful answer, Gordon. I suspected that the differences between a tubeless and a tubed wheel would be that lip to hold the tire better. Perhaps that is what GTD was talking about.
I'm glad someone has had first hand experience with making this combination work. Even if the wheels.ca people had blowout problems, the disadvantage of the internet is that they can say it won't work even if it was just for them, or an isolated incident.
Is there a specific, off-the shelf silver spray paint that works the best to make the wheels look close-to-Alfa spec? Obviously they need some help based on the photo above!
Thanks for the quick response. Now to get the other three!
