Couple of questions:
1. Bought a GUB Ceramic of the tinterweb. To install it, rather than 2 spacers drive side for a 68mm shell, it will only spin freely with one each side. I run two rings and the chain line looks ok. Am I missing something here not having the extra spacer. (With two fitted, when the crank was nipped up, it crushed the bearing before it reached the end of the spline on the spindle. Hope this makes sense).

2. Its a Ceramic bearing and arrived dry. Should these also be packed full of grease.

Off to Mt Keen on Sunday so have some fettling time in hand and want to get it right.

Thanks
