I've got a 2013 Specialized Secteur Expert Disc:

Specialized Bicycle Components

------------------------------------
In 2013, it was spec'ed like this:

All New, A1 Premium Aluminum disc specific road frame with smooth welds, features OSBB, increased tire clearance, and endurance geomentry to ride fast comfortably, and confidently anywhere

All-new FACT carbon disc specific fork with tapered steerer provides ampel tire clearance and the best balance of strength, stiffness, and compliance for a confident ride

Durable Axis CXD wheelset designed for disc with wide rim for tire volume and contact, plus sealed cartridge bearing hub; fitted with fast-rolling Specialized Roubaix Pro tires for a supple ride

Specialized Comp shallow drop alloy bar for serious performance; wrapped with non-slip Specialized Roubaix tape for vibration-damping

New Specialized Pro Pavé FACT carbon seatpost balances stiffness and efficiency with the vibration-minimizing benefits of Zertz technology

Tires: Specialized Roubaix Pro, 120TPI, aramid bead, 700x25/28c

-------------------------------
In 2014, they changed a few things that seemed to be aimed at more comfort:

E5 Premium Aluminum disc frame with Zertz inserts, OSBB, and ample tire clearance provides a lightweight, confident, compliant ride for any adventure

Tires: Specialized Espoir Sport, 60TPI, wire bead, double BlackBelt protection, 700x30c

------------------------------------
I really like the feel, performance and speed of my Sectuer as it stands today on smoother roads. I'm trying to figure out how to make my 2013 spec'ed Secteur more comfortable on 30+ mile rides on really beat up (broken chipseal asphalt, large cracks, multiple unavoidable pot holes, some loose gravel) country roads.

I'm thinking bigger tires. If that makes sense, any recommendations?

Specialized supposedly has a new "Cobble Gobbler" seat post coming out that's supposed to be something. Could that be an improvement?

Or so I need to move to a different bike (Domane 4.x, Roubaix, steel frames) to see substantial improvement?

I'd like to end up with a fast bike that is comfortable on long rides and can handle running through a patch of gravel now and then without me having to worry about wiping out.

What do you suggest? Thanks in advance.
