Anyone else have problems with the Truvativ cranks on their new Kona's lossening up? My new Jake loosened up and chewed up some of the splines. Kona replaced the GXP (kinda low-mid quality) with a brand new Rouluer GXP (hyperblack is good mkay!). It also included a nice new external bottom bracket cup set. They said that this is super common for the cranks to loosen up with the internal bottom bracket designs.
