a maintenance-free pivot with zerks and bearings? that's not maintenance free. teflon-impregnated high-density polyeurethane with seals, maybe. SKF has a new ceramic sealed needle bearing cartrige in standard sizes. NASA $h!t.

personally, i would change marketing tactics. f**K the red-bull drinking x-gamers and their ilk. simplify the pivot point by removing it entirely. start using steel again. reynolds 835 air-hardening tubes over carbon fiber any time. (185KPSI tensile!)
