Does anyone know the q-factor of the current Ultegra ("10-speed")
double crank?

Hi John,

I just measured a 175mm double 6600 crankset. I get 14.3cm from
outer-face to outer-face. The cranks are not mounted on a bike, which
made measuring easier. I assembled the cranks, and held one face flat
on a table and measured the distance from the table to the other face.
I think it is pretty accurate.

Hope that helps!

Joseph
