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 or check out our compatibility chart.
