CL Crank length
Crank length is given by height band; the actual choice should also consider leg length (inseam) and riding purpose. A longer crank makes the pedal circle larger at the same cadence, increasing muscle extension and knee flexion — a longer lever and higher torque, but more effort and more knee load.
| Height (cm) | ≤152 | ≤168 | ≤183 | ≤189 | ≤195 | >195 |
|---|---|---|---|---|---|---|
| Crank (mm) | 160.0 | 165.0–167.5 | 170.0 | 172.5 | 175.0 | 180.0–185.0 |
Notice: For reference only. At the same pedaling frequency, a longer crank makes the muscles contract over a longer distance and changes the power output. Choose the crank length according to your riding purpose — racing, touring or daily commuting.
