Knees like pistons!

Correct:

  1. KOPS (Knee Over Pedal Spindle) is about Fore-Aft position of the saddle, that sets the knee position in relation to the pedal spindle when the crank is level with the forward foot.

  2. The “Knees Like Pistons” is about the Left-Right tracking of the knee during the pedal circle. Generally, you want this to move up and down with minimal Left-Right, side-to-side movement.

    • Everyone is different and a fitter should be looking at many factors when doing a fit. That’s because the knees in, knees out, or any variation is not perfect and prescribed for everyone. Our natural body alignment must be reviewed and addressed accordingly. When done right, this is one step to prevent pain or injury to the knees.

(I am a fitter and deal with this in every fit we do).
