## 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.

**Q: How do you orient the chainring on the crank arm?**
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?**
A: It depends on your application. A new bottom bracket will come with crank bolts. Or if replacing a existing crankset, you would just resuse the old crank bolts.

**Q: Does this product include crank/bottom bracket bolts and caps? If not included, which set should I order?**
A: Hello! The package of this product includes a left crank arm, right crank arm and a chainring with 4PC chainring bolt. Does not include bottom bracket or caps. I hope this answer is helpful to you.

### ⭐ Review
*by N***L on 15 January 2024*

Mounted up with a narrow 113mm bottom bracket and still had to mount the chainring to the inside of the crank arm just to get a 52mm chainline(3mm outside of ideal, but still in the acceptable range). The chainring mounting holes are not centered in the crank arm. This just looks bad, especially since I had to mount the chainring to the inside, making the badly positioned holes totally visible. The chainring has an almost hooked shape to the narrow teeth and the chain jumps very badly in the largest 5 gears and the smallest gear, meaning I only have 3 usable gears that the chain won't come off. It doesn't matter which direction I run the chainring, either. I am very disappointed overall. I am going to try a different chainring to see if it works any better. I thought a "Narrow-Wide" chainring was supposed to retain the chain better, not throw it off worse!
