will have a go!
b4 gyro tabs were fairly standard on frames, they used a cable hanger type thing which u fitted between your top headset cup and the top of the headtube.
i'll have a look tonight and see if i have one, which u can have no probs.
I know i've at least one here, but it may be for a 1" headset, not the newer 1 1/8".
will let you know later.
