i totally agree, but the NJS has very strict standards for their races, and i'm not sure they'd allow the new DA crank design to be used unless everyone else was also using it...then again...who knows? also, even though my paranoia is completely unjustified, i still have a problem with "bonded" materials in important parts of my drivetrain.
i'd like to see a track version of the truvativ rolleur gigapipe cranks though...talk about a sexy crank.
