I’ve just ordered h son Archetypes to use on my CX bike. They aren’t marketed as tubeless ready, but people say they work.
A23s are a little lighter, but reportedly not as well finished and not as stiff as archetypes.
I decided against Stans as the Iron Cross won’t let you run road pressures and Alphas seemed a little spendy and might be a bit narrow for CX tyres.
I haven’t ridden any of these rims…
