me and my buddy are tyin to install his new raceface evolve crankset. we've got the bb installed and the spacers are set to what we need. now were trying to tighten down the drive side, but the bolt wont grip at all. we tried tapping it with a rubber mallet to see if it maybe had to move down or something...but nothing is working. also everything is greased up. are we doing something wrong, because neither one of us has ever installed a raceface crank set before.
