If stack/reach are not yet known measurements, start experimenting with different spacer stacks, stem lengths,
handlebar heights/widths and handlebar/brake lever positions.
Fig.5:
Assemble the chosen spacer stack in order. The spacers are keyed to fit either the low or high stack
configuration. Low and high stack parts cannot be interchanged.

Fig.6:
Install the stem
L
onto the steerer tube (the steerer tube will stick out the top of the stem, which is ok at this
time). Do not torque! Tighten the bolts enough so that the stem doesn’t move.
Fig.7:
Apply carbon friction paste to the surfaces between the stem, faceplate and handlebar. Install the
handlebar
N
against the stem. Adjust the angle of the handlebar until it’s in the desired position.
Fig.8:
While holding the handlebar in its desired position, rotate the faceplate downward so that there is no
gap between the faceplate and the stem body, at the underside of the stem. The gap should only be above the
handlebar. Torque the stem bolts to 100 in-lbf (11.3 Nm).
If the faceplate is not bottomed against the lower edge of the stem, the faceplate and handlebar can rotate
downward under rider weight until the faceplate bottoms out against the stem below the handlebar.
Fig.7:
Install the brake levers
M
and adjust the angle until they’re in the desired positions.
Fig.7:
Once the stack/reach and handlebar/brake lever angle positions are determined, mark the handlebar and
lever positions, then disassemble the handlebar from the stem.
B. ADJUSTING SADDLE AND SEATPOST POSITION
To prevent damage to the frame and/or seatpost, it is important to have a minimum amount of insertion in the seat tube.
Use the sight hole in conjunction with the minimum insertion/maximum extension (min/max) mark on the seatpost.
The seatpost MUST be visible through the sight hole, AND the seatpost must be inserted into the frame deep
enough so the min/max mark on the seatpost is not visible.
If the seatpost is at the min/max mark and the seatpost is not visible through the sight hole, the seatpost is not
inserted deeply enough into the seat tube and should be lowered until it can be seen through the sight hole. This
may result in the saddle being too low. If so, the seatpost must be replaced with a longer seatpost.
