Here's another view.

I have 2 bikes, a Trek Emonda SLR with 25mm tires and a Cannondale SuperX CX with 32mm tires.

The SuperX is my winter bike and cruises over all the rough roads like a Cadillac. The frame and wider tires really absorb the bumps compared to the Emonda... no need for gimmicks. But the Emonda just handles better an climbs faster due to better power transfer.

I can tell you there's a rather bumpy decent I ride regularly and when I did it on the SuperX, for the first time, I greatly increase my MPH. This is why the pros only ride the Roubaix on cobble classics and no other time.
