MORE Stance Width Adjusting 4167874998
Knee position at the top of the pedal stroke is the driver for setting stance width.
In the above scenario the knee is outside the toe line at the top of the pedal stroke but comes inward near the bottom of the stroke. Why?

It is actually quite simple. The stance is not set wide enough. Since the knee is attached to the foot (and pedal) it has no choice but to follow the foot (at the bottom of pedal stroke). Some old school solutions might have been to tell the cyclist to bring their knee inward. However, life rarely works that way. The real solution is to move the foot outward, underneath the knee as the knee is able to go where it wants to at the top of the pedal stroke…it has no choice at the bottom.
Remember: When you clip into the pedal, stance is selected for you.
“You self-select your stance (width) when you walk, run, stand or jump. It is the bike fitter’s job to help select it for you on the bike.””
– Dr. Katrina Vogel MS DPT.
When the knees go out, they are trying to tell you something. So adjust by moving the foot underneath the knee to select proper stance width and alignment.
Please Note:
In this example, we’ve shown you the right leg only in order to simplify our tip. In practice, you would do the same process with the other leg.
Hex+ 20mm Pedal Spacers!
Hex+ 20mm Pedal Spacer Sets (part# 4030220) allow for larger adjustments when the lateral adjustment of the cleat simply isn’t enough.
And our new Hex+ adaptor solves a common problem for many who’d like to use a 20mm Pedal Spacer but have the wrong model/brand of pedals to allow their usage.
Look Keo, some Shimano, Crank Bros, etc., all need a Hex key to install their pedals into the cranks. 20mm Pedal Spacers do not allow for hex key.
The 6mm to 8mm Adaptor and the hollow 20mm Pedal Spacer lets pedals without wrench flats work with 20mm adjustment options!
The NEW Hex+ 20mm Pedal Spacers (#4030628) are available for purchase
