Inner Race Width - 19
Though stainless steel may have about 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings
The eleven tooth size and profile with 5mm bolt-holes are designed as an upgrade for most 11 speed Campagnolo derailleurs
This is ideal for pulling bearings from freehubs and hubs that utilize bearing spacers instead of axle stops
This process also provides a secondary advantage of heat treatment making them tougher
