Here’s a nice trick.
We can now save money converting DT Swiss ratchets to XD from Hyperglide by buying just the freehub body (HWRAAX00S3114S). It used to be that you’d have to buy the body, ratchets, grease, and springs (HWYAAX00S3188S). It’s about half the cost.
The problem is that the new FH body doesn’t include the spacer. That’s important and needed. The trick is to just cut the rim of the spacer from the Hyperglide body diameter of 29.0mm down to 23.6mm for the XD body. Simple and easy. Lot’s of money saved.
Shown below are the 16mm spacers used on the drive side of 142/148 width hubs.
