tungsten carbide steel blade for
alloy/steel steerers or carbon
cutting blade for carbon steerers

Fork Installation Overview
Installing a new fork is a three-step process:
STEP 1) Check headset components for compatibility and assemble the fork
into the headset so you can measure and mark the steerer tube cutting length.
STEP 2) Remove the fork from the headset and cut the steerer tube to length.
STEP 3) Reassemble the headset and fork, add handlebars, align and tighten.
WARNING: Failure to follow these instructions may result in premature
failure leading to a crash resulting in serious injury.
STEP 1 CHECK, ASSEMBLE AND MARK
1. Double Check Component Compatibility: Check the fork, headset,
headset spacers, stem steerer clamp and all other parts required
for proper assembly to ensure they all have compatible dimensions.
Incompatible dimensions can cause component failure.
Carbon steerers can only be fitted with a rear slot-style clamping stem.
WARNING: Only use rear slot-style clamping stems on carbon
steerers. Wedge-clamp stems must not be used and could result in
failure (Fig. 1).

Carbon & Metal Fork Installation Instructions - ASTM 2
• Torque wrench with Newton
meter (Nm) scale
• Metal file
• Cutting fluid
• Grease
• Fine-tip felt marker
• Rubbing alcohol
• Protective eyewear
• Star-nut setting tool
• Fine grit sandpaper
2. Remove Burrs and Sharp Edges: Wearing protective gloves, examine
the stem and headset parts for burrs and sharp edges that may contact
the steerer tube. Remove burrs and sharp edges from carbon components
with fine-grit sandpaper. Use a metal file on metal components.
3. Install the Crown Race: Hold the fork with one hand and use a crown
race setting tool and hammer/mallet to install the crown race onto the
steerer tube, following the manufacturer's instructions.
WARNING: Do not place the fork on the dropout tips or support the
fork in the crown area while installing the crown race. Doing so can
damage the fork (Fig.2).
