Choosing the correct spoke length is critical for a safe and properly tensioned wheel.
You’ll need:
- Hub measurements (flange diameter, spacing)
- Rim ERD (Effective Rim Diameter)
- Lacing pattern (e.g., 2-cross, 3-cross)
How to get the right length:
- Use a spoke length calculator
- Input your hub and rim specs
- Select your lacing pattern
Key tips:
- Even a 1–2 mm error can cause issues
- Too short → weak engagement
- Too long → can bottom out or damage the rim
If you’re unsure, it’s always best to double-check measurements or consult a trusted wheel building resource before ordering.
