"These hubs are a generation before King decided to take things to Centerlock and introduce the twin drive system. And while ISO hubs made a production comeback in 2023, these hubs remain highly desirable for a number of reasons.
- Stainless Steel XD Freehub
- Larger FH bearings
- The SD fronts are lighter than the AB models
- SD fronts can be converted to TA15x100, TA12x100 and QR 9x100
- Rear hubs can be converted between XD and HG with just a driveshell instead of swapping a full conversion kit - axles, freehub and bearings.
- No need to purchase Universal hub tool if you have the older ISO tool."
