Odyssey invented the Gyro and
its still pretty much the same.

The G3 gyro system is what todays
1,1/8 bikes with internal Headsets 
need, designed to work with bikes
that have inbuilt or remouvable Gyro
tabs but if you have an 1,1/8 frame
with older Press fit style headset then
it comes with lower plate included.
