Which spindle do I need?

Choosing the correct spindle depends on your bike's frame and drivetrain setup. But as a general rule of thumb, compatibility is as follows:

• 130mm spindle – dirt jump and non-boost bikes
• 136mm spindle – most modern trail and enduro bikes with boost spacing
• 145mm spindle – downhill bikes

If you're unsure which spindle is right for you, check your bike manufacturer's website for your specific bike's sizing and spacing.
