The Answer BMX Integrated headset reducer allows you to run a 1? front end on a 1-1/8? head tube frame. The headset installs like a typical integrated headset with an OD of 1-1/8? and ID of 1?. This is an attractive option for those wanting to move a young rider to a larger frame without adding the weight of the 1-1/8? front end just yet. Available in black only.
