FORM Leg Length Shim Speedplay – Precision LLD Alignment for Wahoo System
FORM Speedplay Leg Length Shims are an advanced biomechanical solution for cyclists struggling with leg length discrepancy (LLD). This system allows for equal leg reach, which stabilizes the pelvis and ensures symmetrical extension at the bottom dead center of the crank.
Important note: The included screws are compatible with current Wahoo Speedplay cleats (Nano, Zero, Aero). If you are using older Speedplay V1/V2 versions, please contact us for the correct mounting solution.
TECHNICAL COMPARISON: SPEEDPLAY vs. ROAD 3-HOLE
| Characteristic | FORM Speedplay | FORM Road (3-Hole) |
|---|---|---|
| Maximum compensation | Up to 15 mm (Connecting) | Usually up to 5-8 mm |
| Contact surface | Non-slip texture | Anatomical shoe profile |
| Power meter compatibility | Yes (Powrlink) | Yes (Favero/Garmin) |
POSITIVE EFFECTS AND BENEFITS
- Eliminates pedal reach: Equalizes leg reach at bottom dead center, preventing asymmetrical calf and foot strain.
- Hip stabilization: Reduces the tendency to "rock" the pelvis, which protects the lumbar spine from overload pain.
- Connection security: The anti-slip surface ensures that the block does not move relative to the pad even at extreme support heights.
- Biomechanical Support: Allows for smooth, symmetrical extension of both legs, improving overall pedaling efficiency.
