In the bag with the in line cable adjusters also came a thin metal disk with a hole in it the exact same size as the bottom bracket. When you put the disk over the bb hole, the edge of the disk appears to be about .25 inch bigger diameter than the bottom bracket.
Someone said you put the disk on the drive side and lock it in place with with the drive side cup.
It is supposed to stick up a bit right above the carbon bottom bracket so if the chain derails to the inside it ends up flopping down on the disk instead of marring the carbon.
Anyone use/know about these?
