G1 SIZING AND COMPATIBILITY

SIZE SMALL:

Head tube outside diameter must be 54mm or less
We recommended use with frames that use 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 line up with the width of the bottom of the gyro. Using a vernier caliper is the best way to measure.
Steer tube must have 20mm of extra length

SIZE LARGE

Head tube outside diameter must be 54mm or greater
We recommended use with frames that use 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 large G1 (74mm) however, gyro tabs are not included and may need to be customized to line up with the width of the bottom of the gyro. Using a vernier caliper is the best way to measure.
Steer tube must have 20mm of extra length
