## Questions & Answers

**Q: What's the difference between the seventh and ninth choices in this listing?**
A: The seventh is - 40 teeth/8mm bore, the ninth 60 teeth/8mm bore. The 60 teeth is bigger diameter than 40 teeth.

**Q: What is the inside bore size of the idler pulley?**
A: The drawing shows 5mm

**Q: Can I use this for a Velec electric bike chain?**
A: This is a Timing Belt Idler Pulley made from Aluminum. I did not use it on my project, but used pair of flanged ball bearings for the pulley I need. If your bike chain made from steel metal I wouldn't recommended to use as a pulley for it. Aluminum will be worn out very quick.

**Q: What is the flange diameter on these?**
A: Flange diameter is 0.704"
Flange thickness is 0.039"
Belt Hub diameter is 0.473"
Belt Hub width is 0.255"
