Are you in pain? Does your back/ass/knee/hip/neck hurt?

Elbow

Loading chart...
  • Elbow angle is the measurement from the forearm to the upperarm.
  • Elbow anlge between 90 and 175 are acceptable depending on the riding style and rider's back and tricept strength.
  • Riding with your elbow near 180 degrees can cause excess stress on your elbow and so it is recommended to keep the angle below 170.
  • A fit with too much elbow extension is commmonly remedied by shortening the stem to decrease reach.

Shoulder to Wrist

Loading chart...
  • Shoulder angle is the measurement from the torso to the wrist.
  • Shoulder anlge is expected to be near 90 degrees.
  • An angle significantly larger than 90 indicates too much reach, and may cause excess stress on the back, core, and arms

Knee

Loading chart...
  • Knee extension is measured from the thigh to the shin.
  • The generally acceptable max (extensition) and min (flexion) knee angle is 30-100 degrees.
  • Hip and ankle range of motion impact the available healthy range of motion for the knee.
  • A fit with too much knee extension is commmonly remedied by lowering the saddle

Ankle

Loading chart...
  • Ankle angle is the angle between the foot and horizontal.
  • Most riders should have a neutral ankle angle of +5 to -20 degrees.
  • An excessive negavite ankle angle (toes down) may be due to excessive saddle height, however this needs to be assesed in coordination with the knee angle.
  • Some ridiers are healthy running with large toe down angle, where as this can cause knee issues in others.
