Hi Craig,
I have a Crossmax ssl lefty hub that has had play when pushing the wheel towards the lefty. Not much, but enough to cause me to cut out some aluminum sheet and make a spacer which I placed behind the disc side bearing. The play stops after the wheel is mounted but returns after riding the bike. I tried a thicker spacer but the bearing has too much drag and the wheel won't spin. Is another spacer needed behind the the drive side bearing as well? I know there is a discussion on this but I don't see where I can get an answer to remedy the play.
Thanks,
Dino Vizzoca
