Head tube outside diameter must be 54mm or less. Using a Vernier Caliper is the recommended way to make this measurement.
We recommend using with a frame that uses a press-in headset top cup. This will prevent any compatibility issues from using the G1 with different gyro tabs.
If your frame does not use a press in top cup, you can use gyro tabs that line up with the bottom of the small G1 (69mm) however, gyro tabs are not included and may need to be customized to align with the width of the bottom of the gyro.
Steer tube must have 20mm of extra length
