Ok I am building a bike up, and i have a used frame which came with a headset. In this case a Cane Creek S2. when assembling it small split ring fell off the lower bearing. Is this a part of the bearing it self, or is this the "race" that sits between the bearing and the forks that has got stuck to bearing because of the grease, if not I'll have to buy a race.
PS: I know those photos make it look fairly beat up, but it isn't that bad, and is still smooth.
