Title G1 Gyro Brake System - N/A - N/A - Black - Small PLP|Largest Cog flathead screwdriver and quick linkLever, cables, and calliper not included. Size Small 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)
