Iv been watching quietly in the background but im iv not really seen anything that makes me go woooha for a while, but im surprised no one has posted this yet.
Yeah, saw those the other day... really nice, some kamtail action for aero and tucked away brakes. There was a funny photo where one of the guys from another team, Euskatel or Moviestar I think it was, was drooling over the new RSNT bikes. Not a fan of the 2-bolt only mounts for brakes though.
I think the only reason they have put the calliper there is structural. Move all the braking forces away from the seatstays and really optimise the them for stiffness/ride. Reposition the posts down near the bottom bracket where its nice stiff and chunky and the post are close to a node to minimize flex.
I wonder if there would actually be more or less of a flex issue at the CS than the SS? There's definitely more movement around the BB area but maybe the rim stays more central at the CS?
