Service Guide

IMPORTANT: Always hold the spoke at the rim-side ferrule when truing or tensioning. Never hold the spoke at the hub-side ferrule or allow the spoke to twist or spin. Any spoke rotation during service can damage the spoke and compromise its strength.

Tools Needed

• Park Tool SW-15 or SW-17 (5mm hex nipple tool)
• Park Tool SW-3 blue spoke wrench (3.96mm)

Step 1 — Prep

1. Remove tire and rim tape.
2. Clean rim surface with rubbing alcohol.

Step 2 — Remove Damaged Spoke

1. Unscrew the spoke from the hub using the SW-3 (or similar spoke wrench) to help break the threadlock.

Step 3 — Prepare the New Spoke

1. Apply low-strength threadlocker to the rim-end threads
   (spare spokes usually arrive pre-applied).
2. Apply grease or linseed oil to the hub-end threads.

Step 4 — Install the New Spoke

1. Insert the spoke through the rim and align with the hub hole.
2. Thread the spoke fully into the hub by hand.Do not force threads.
3. Back the spoke out ~⅛ turn to allow slight free play.

Step 5 — Tension the Spoke (Important)

1. Hold the spoke on the rim ferrule using the SW-3 spoke wrench.
2. Using the SW-15/SW-17, turn the hidden nipple to tension.

⚠️ Critical:
Never hold the spoke at the hub ferrule or allow the spoke to twist.
Spoke wind-up can cause damage and premature failure.

(If you’ve built wheels with bladed spokes, this is the same process.)

Step 6 — Final Tension & True

Continue tensioning until the wheel is true.

Target tensions:

• Front non-drive: ~120 kgf
• Rear drive-side: ~120 kgf

We use the Wheel Fanatyk iGaging tensiometer. Refer to the tension chart for full specs.
