Fork and Stem Install -
1. Install headset per headset instructions.
If headset is already installed install fork back
into frame. DO NOT grease the fork steerer tube.
2. Unless the desired stem height is already
determined, it is recommended that the initial
installation of the fork be done with the maximum
allowed stack height (40mm) to allow the greatest
range of adjustability. Spacers can be placed above
or below the stem to adjust your position. Once a
more precise stem height is determined, a second
cut can be made to eliminate any spacers that may
have been placed above the stem to achieve the
desired position.

3. Carbon steerer tubes should extend completely
through the stem for proper clamping pressure
and safety. It is recommended to have a minimum
of 2mm of steerer tube extend above the stem and
use a 5mm headset spacer between the stem and
headset top cap. More than a 5mm spacer above
the stem is not recommended.
Warning! Do not permanently place more than
a 5mm spacer above the stem and no more
than 40mm of spacers below the stem. Placing
too many spacers above or below the stem
defeats the purpose of the expander plug’s
ability to support the steerer tube and stem.
4. Install stem and align with wheel. Tighten stem
clamp bolts to manufactures recommended torque.
