That's good to hear about the disc mount, i know me and a few other members have been rattling on about that for some time. As for the snail cam hole, the only reason I've been going on about it is becuase it is just a hole. If there was any amount of extra material, work, design or cost, it would obviously be a non issue. I hope I get round to trying the integrated tensioning systems myself, but chances are in this country it's unlikely, some rider the other day said to me "what the hell, are they hedgehogs in your front rim?!"
