## 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
