The doper's Dr. agrees with that statement.

The pros are now riding wider spreads with 10/11 speed. Many are riding 53/39 with 11/26 everyday at the Tour(LA).

I believe the majority of bikes should be sold with 50/36 & 11/(26,27 or 28).

More people are riding higher cadence which demands lower gearing.
