Hi Philippe. Dynafit doesn't sell those separately but we have a couple used sets (Radical roof screws).
Hi Kelly, it fits albeit a little loosely. The bungee secures it fine though. Here is a picture. Yes we can work with you locally.
Hi Johnhboy, there is a rigid wire that runs across the top and down each side of the main internal compartment. Here is a picture. It can be removed if you prefer no structure.
Hi Mike, the only brake that I know would work is the Kreuzspitze. It slides into the crampon slot. Check out the Radical ST for an integrated brake.
Hi Wally, yes sir, the 90s will fit great on that ski.
