The q-factor is a little complicated on this crank set because the pedal threads are inset slightly from the outside of the carbon crank arm. What this means is that some pedals need to have a little pedal spacer inserted so that the flange or shoulder on the pedal doesn’t hit the carbon crank arm. And some pedals, ones without a big shoulder, don’t need a spacer and will sit nicely in the recess on the cranks. So Lightning lists the q-factor as:

149mm with pedal spacer
145mm without pedal spacer

Make sense?

Sweet Nico — can you speak to the Q-Factor?

Thanks JJ for pointing out my mistake. I’ll fix it now.

Hi Nico-

Those are sweet cranks but you have the patent license backwards. Specialized bought the patent from Lightning and gave a Lightning a license to use the design.

Thanks
