i agree with this.
in my opinion the 2019 roubaix will ride significantly smoother than any allow bike made.
the 2019 roubaix sport has a shock absorber built into the fork for 20MM of travel to absorb bumps without feeling them. the rear stays also flex over 10mm to absorb bumps. you can also upgrade it with a better seat post off the higher level bikes that also flexes so give additional cushion to smooth out the road. it is also designed to allow tires up to 32mm to smooth out the ride.
quote from a bike radar review. Overall, the Roubaix is one of the best ever endurance bikes, and though this Sport model is on the expensive side for the level of equipment, it does deliver the full-fat full-flavour Roubaix experience.
If comfort, closely followed by exciting handling, are at the top of your wishlist, then the Roubaix could be the bike for you.
