SI COMPRESSION ASSEMBLY KP017/ INSTRUCTIONS
The following procedure should only be completed by a professional bike mechanic.
1. Assemble the fork, headset, spacers, and stem without tightening the stem bolts onto the head tube. When
the system is assembled, the carbon steerer tube should be 2-3 mm below the top of the stem. All spacers
must be located below the stem and within the maximum stack height as shown. No spacers may be used above
the stem.
2. Set-up the compression assembly before inserting it. Adjust the length so that the expander is located at
lower stem bolt. The top cap and the expander end provides critical support to the carbon steerer when
tightening the stem bolts. Adjust the length by threading the top cap on the expander parts.
3. When the assembly is the correct length, insert it into the steerer tube. it is designed to fit snugly inside the
steerer. insert an Allen key through the access hole in the ToP CAP and into the EXPANdER BoLT. Tighten the
to the specified torque.
4. Now, to set bearing preload, insert a 6mm allen key into the hex shape in the ToP CAP itself. Turn the entire
top cap clockwise to increase preload. Turning it counter-clockwise will decrease the preload. When the
headset preload feels correct, turn the stem to align the handlebar and tighten the stem fork clamp bolts
to the torque specified for the stem. Consult the stem manufacturer’s instructions. The torque values for
components are often marked on the part.

CABLE ROUTING
The top tube guide
KP063/
is removable so that brake cable may be routed inside the tube. The guide is
secured in the tube opening by the installed brake cable tension. Make sure the guide is seated properly
in the top tube opening when installing and connecting the rear brake.
Be sure to use ferrules on DT housing ends.
When using Shimano di2, the dT openings are fitted with rubber seals included in
KP298/
. Notice the
small opening below the rear brake headtube inlet. This is for di2 cabling. The rear derailleur exit is also
included in the di2 kit .
