Quick Summary

What to Compare Before Buying
- Crankset type: Check that your setup uses a square hole crankset, because this is the stated fit.
- Installation size: Confirm that 8 mm hex fitting matches the tool you plan to use.
- Quantity needed: The pack contains 10 bolts, so compare that with the number you need to replace or keep in reserve.
- Part format: Make sure you need crank arm fixing bolts rather than another crank or bottom bracket part.
Before You Decide
Confirm the square hole crankset fit, the 8 mm fitting size and the 10-piece pack quantity before choosing an offer. If your crank setup uses a different fixing style, a different part will be needed.
