## 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.
