Review: Excellent value - Wanted to go to a 1x setup but my original crankset had riveted chain rings that weren't easily removed so I went the easy route and swapped them out to these. Very nice fit and finish. Not too heavy, not too light, just right. Chainring works well with narrow wide multi speed chain and hasn't skipped a single tooth. Would recommend for a very budget friendly crankset swap or upgrade.
Review: Works as it should - Got this to replace my bike's chain wheel, and this was really nice. Works well with the other pedals I had also gotten.

## 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.
