How are you getting on with this ssmith? I’ve done some more digging and the Supermax hub is only available in 32 hole. The stock Mavic wheels are 24 hole, therefore the stock setup is running a standard Lefty Hybrid hub and brake adaptor.
I ask because I am planning to order some wheels in a couple of weeks. I’m not sure what the benefit of the Supermax hub is, but to use it, at the very least, we need a different brake adaptor. I don’t suppose your hub is fowling the adaptor and preventing it from going on?
I’m inclined to have mine built up on a Lefty Hybrid hub since that’s what we have already, albeit I’ll use a 32 hole variant. However, if a Supermax hub can be used simply by swapping out the brake adaptor then that’s a tempting additional expense.
edit: did you screw the bolt all the way through into the hub before mounting the wheel? You need to make sure it is all the way in, then it will spin freely in place, then mate to the spindle and let it pull it on – I noticed in one of your pictures that the bold was not already in there?
