## Questions & Answers

**Q: Can I use this to convert rear from 160mm to 203mm?**
A: This should convert 180mm to 203mm, not 160mm to 203mm. 150mm to 203mm would be a 43mm adapter... am i wrong?

**Q: Does this come with hardware?**
A: Yes, this came with the hardware needed to mount to the bike and caliper.

**Q: I have a 180mm rotor on the back wheel now and would like to upgrade to 203mm, will this adapter work? Thanx**
A: This adapter works great. With the new 203 disk, my Kona ebike conversion stops at any situation with confidence

**Q: Does it come with screws?**
A: thought it comes without screws.
