Any word on production of the rear rack?
Looks like its going to be a nice one. It'd be clever if it came with a couple spacers for each post, so you could adjust the level of the rack in relation to your panniers. Say for example, 15mm and 25mm spacers for the frontward posts, to give you a range of between 15mm and 40mm. Front and rear posts would have to be different heights to get the rack level fore n' aft.
Here's a great pic by everywherevirtually, where you can see the prototype, and also shows how well the A-S bars protect the bike!
