We scrounged all the Axys A arms in stock within about 300 km of Blue. The two broken sleds are back in action, and the rest of us on Axyses of exercising a little caution. Made it through days 2 and 3 without any damage.
gd, I don't know the answer. But are there parts fiche / breakouts available online? That would tell the answer. The Axys uses the same ski so the rubber should be interchangeable, I'm just not sure if it is any different than the Pro rubber.
