Our Left and Right stainless steel 20 mm Pedal Spacers are used with knees that track outside the pedal by adding length to the pedal axle. Designed to move the foot out and away from the crank arm to provide more foot clearance, they add to stance width for cyclists needing help with knees-out, excessive toes-out, extra wide feet, wide hips, or for those with discomfort on the outside of the knee. 
These two (2) 20 mm Pedal Spacers are sold as a pair.  
Note:

• 20 mm Pedal Spacers will only work with pedals that have a flat spot in which to tighten/loosen the pedal. Our Pedal Spacers willnot work with pedals which can only be tightened/loosened with an Allen Key.

• 20 mm Pedal Spacers are not recommended for use with carbon cranks.
