Kappstein makes some interesting stuff but I gotta wonder what the point is for this? I saw it and was like hmmmm...kind of cool but nobody else makes it so it makes it semi-proprietary and that just doesn't jive as well with me. 1/8 and 3/32 has been fine and surely you could develop that into something even better. Plus with all the modern lightweight technology you could easily save weight elsewhere on the bike or have a lighter drivetrain in the standard category.
