A totally different stage than today's stage 6.
Different conditions (the cobbles of Northern France) and therefore very different equipment.
Note that the Pave' bikes of stage 5 & their specialized equipment were totally absent from stage 6, as was the mountain equipment we'll see trotted out in the Pyrenees & Alps.

Modern Pour Tour teams have the ability to replace & modify gear daily to achieve the old maxim: "horses for courses".
