222 22 22 - 20mm pedal spacers and world record

http://vanessablack.zenfolio.com/p953636325/h20471409#h2187d9cc George Hood did it - a new world record http://www.urbantrigear.com/
Bernie Conway a local fitter called us after George started on his quest. Lateral knee pain was the reason- add the 20m pedal spacer and the pain went away. Way to go Bernie for being on top of it and makeing sure George got the record.

No 20mm pedal spacers on carbon cranks...well most carbon cranks

Why do you not recommend 20mm pedal spacers with carbon cranks?
Thanks for the question. To be honest it is not so much that BikeFit recommends this but rather some manufactures do not support this.

This is a tough one for us to hold back with our actual thoughts but we will….for now.

This is what a few companies have told us. I may not have this word for word so do not hold us accountable to exact wording but here is a synopsis of a few conversations.

Use of 20 mm pedal spacers – what we think

Zipp –    Voids warranty
FSA-     Voids warranty on ALL their cranks … and they said they will void warranty even if you use a longer pedal spindle – now I did not get a range or what they actually consider a longer spindle as not all pedal widths are the same – most are close but again not all are the same
Truvativ – waiting for an update
Specialized – says they are OK if you use a 20mm pedal spacer on their carbon cranks.

So guess what I ride? I love my Specialized Tarmac S works with carbon cranks.
Right side - I go back and forth between a ½ inch longer spindle (Speedplay Zeros - which I actually pay for) or I use a regular length spindle and a 20 mm pedal spacer.
Left Side -I use a ¼ inch long spindle..

Hope I get to ride a Specialized for a long time!

Longer lefts?

During bike fits, we note the cyclist’s need for longer/shorter pedal spindles or need for extenders. At first we did not think it was that big of a deal. However, the need for longer/shorter spindles has become beyond note worthy.

Literally, we are finding AT LEAST 3 of every 5 cyclist’s stance width requires a spindle width longer or shorter than a standard width pedal.

To track this data even more closely we are noting the need per foot being fitted. In other words 5 bike fits would = 10 feet.

We have recorded as high as 9 of 10 feet needing longer or shorter spindles in a weekend of bike fitting (5 bike fits). That means not one cyclist fit on a standard pair of pedals.

While tracking this information, we noticed the left foot needs to be placed more laterally than the right foot to be accurately placed under the knee. At times, we move the right foot in and the left foot out by changing cleat position. Sometimes, we use a shorter right spindle only. In most cases the left spindle needs to be longer. We are starting to gather a LOT of right pedal spacers and we are now asked at least once a week if we sell “left” pedal spacers only.

What does that mean? One day you will not just buy a pair of pedals but be sized for the correct width pedals (per foot). What is the only pedal manufacturer to address this issue? What pedal companies do you wish would figure this out?
