Made in large batches, however we only internally grind 6 at a time as there is at least 2 internal diameters. please specify accurate 'outside of hub / sleeve' diameter so the correct one can be selected.

2 required so please measure both as the 1st / 2nd sleeve might be different to the 3rd / 4th sleeve
