## Questions & Answers

**Q: Can the 12mm pin be removed?**
A: NO, I bought this on 1/10/2022 and the pin cannot be removed.  It shows a hex nut in the picture, but mine is riveted on with no way to remove the center pin.

**Q: What size is the nut?**
A: It fits into a 25.4mm or 1" wrench.

**Q: Is the internal cavity deep enough to go over the left 12 mm axle spacer to allow removal of the center lock brake disc nut?  Needs to be about 15 mm.**
A: No Problem. You should have a few mm to spare.

**Q: Do I need to buy this instead of old/regular 5.2 which works with 5mm skewer wheels?  It's not like the cassette is not centered threading the ring on**
A: No, the FR-5.2 would work or the FR-5.2G with the guide pin also works very well.
