## Questions & Answers

**Q: is the price for 2 bearings? Or only 1 item?**
A: Mine was a set of 2. One for the drive side and one for the non-drive side. Make sure you are using it for the correct BB. It must be for a 24mm spindle and 37mm shell. Also, take care not to damage your outer seals. It does not come with new ones

Put a set of these bearings in my Wheels Manufacturing Bottom Bracket. ABEC 5 ceramic hybrid are the highest rated bearings I can find in this size. I will get another pair so I can always have a clean set ready.
