## Questions & Answers

**Q: How can I determine if this is the right product for my model?**
A: Because this Cranksets is square hole shaped, you will need a square tapered bottom bracket to go with it.Note that this crank is a 170mm size and the length of the crank is chosen according to personal habits.

**Q: How do I adjust the chain alignment? Is there a spacer I can put somewhere to help centre the chain?**
A: The chain ring mounting area has two sides. Placing them on either side will move the chain ring about 10mm. Do not use washers between the crank and the ring because there are no chain ring bolts that are long enough.

A: One the crank arm attaches to the chainring and then to the bottom bracket square taper bolt the other crank arm attaches to the bottom bracket square taper bolt on the other side one arm points up the othe points down direct opposite see less.

**Q: What is used to secure the arms to the square taper bottom bracket arms if no screws or caps are included?**
