Anyone out there know where to find a 41mm hex/allen key to remove the bearing retainer on the rear wheel of the Gen 2 VMAX? I built something out of a piece of flat bar and ground it down until it fit into the corners and it works good enough but I am a tool addict and want one. p/n 90890-01525 or YM-01525 I looked online and all I could find was ridiculous prices. If anyone has a cheaper/better alternative, that would be great too. Thanks.
