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.
CUTTING THE FORK STEERER TUBE
USA
1.Once the initial stem height is achieved, make a mark on the steerer tube at the top of the stem. Place the cutting line 3mm below the mark to allow for the space needed for the 1mm lip of the expander plug. The end result is 2mm of space. (Fig. 2).

2.Wrap the area where you intend to cut
the fork with several layers of masking tape. This will limit fraying of the fibers, resulting in a cleaner cut. Once
you’ve wrapped the layers of tape, determine the precise location of the desired cut with a pen mark on the tape. To avoid fraying the composite fibers, it is recommended that a carbide grit toothless saw blade be used. A fine tooth (36 teeth) saw blade is also acceptable. Double check all measurements to make sure the steerer tube will not be cut too short. It’s easier to measure twice than to buy a new fork.
NOTE: It is very important that the steerer tube is cut straight. For best results, use a steerer tube cutting guide tool.
3.Once the steerer tube is cut to the desired length, remove all burrs at the top of the steerer tube by rounding out the edge with emery paper or a fine grit sand paper. Only sand the edge, not clamping surface! Wipe off all excess dust. Be sure not to breathe carbon dust!

INSTALLING THE FORK

NLD
1.Install the 48mm Long Expander Plug (Fig.2). Recommended torque is 100
The E100/S90/S120 steerer tube requires the use of the RED (22.5mm O.D.) Specialized 48mm Long Expander Plug (Fig. 2) supplied with the fork. Do not use a star nut, as it can damage the inside surface of the steerer tube. Damage to the steerer tube can result in failure, causing serious personal injury or death.
2.Place the fork back into the head tube and clean the stem interface of the steerer tube with isopropyl alcohol.
3.Place the desired amount of headset spacers to achieve proper stem height, followed by the stem and the top preload cap.
NOTE: Do not twist the stem onto the steerer tube. This can result in damage to the surface, which can render the fork unsafe.
4.Install the disc brake and brake housing guide on the fork. Make sure the brake housing routing doesn’t touch the tire when the fork is fully compressed and that it doesn’t interfere with the controls on the handlebar when rotated. Do not overtighten the bolts. Refer to the disc brake manufacturer’s owner’s manual for recommended torque specifications.
