Frequently Asked Questions

Q: What chain size is this rear sprocket engineered for?
A: This sprocket is designed to fit a 520 chain size setup.

Q: What material is used to construct this rear sprocket?
A: It is precision-machined from high-strength 7075-T6 aluminum.

Expert Pro-Tip: Always inspect your front sprocket and chain condition when replacing your rear sprocket. Installing a new aluminum sprocket onto a heavily worn, stretched chain will cause premature tooth wear and ruin the components rapidly.
