All models are shipped with the zero offset cup installed. Switching the headset cup steepens or slackens
the head tube angle by +/-1 degree.
The bottom headset cup is universal for all headset cups. The cup has a spherical interface with the head
tube and will move with the angle of the steerer tube.
Changing the headset cup position and/or stem spacer orientation can affect the relationship between the
head tube and the stem causing an interference that can lead to frame damage. Before fully torquing the
stem, make sure there’s no interference between stem and frame across the range of stem positions during
normal steering. In some cases, adding a 5 mm spacer below the stem may be necessary to avoid contact
between the stem and frame.
