Calculate Optimal Crank Length

Thigh Length  (From point of rotation at hip to point of rotation of knee)  cm

Shin Length  (From point of rotation of knee to center of pedal spindle)  cm

Hip's Horizontal Distance  (Horizontal distance from vertical line through bottom bracket to point of rotation of hip. Rear direction, positive, forward negative)  cm

Hip's Vertical Distance  (Vertical distance from line through bottom bracket to horizontal line though point of rotation of hip)  cm

Crank Length  From mm    To mm

Thigh Extensor Fit Points  N m

Thigh Flexor Fit Points  N m

Shin Extensor Fit Points  N m

Shin Flexor Fit Points  N m

Pedal Cadence  rev/min

Pedal Model Points  (12 is a good value)
