Summary
The Specialized Roubaix is celebrated for its exceptional comfort and innovative features, such as the Future Shock suspension system and CG-R seatpost, which provide a smooth ride over rough surfaces. It's noted for its light frame and race-worthy efficiency, though some find its aesthetics and initial suspension feel unconventional. Comparisons often highlight its competition with the Trek Domane and Specialized Tarmac.
Future Shock suspension system improves comfort and control
Lightest frame Specialized has ever made
Highly adjustable fit with different springs, stems, and bars
Good performance on rough surfaces like cobbles
Remarkable comfort and vibration dampening
Future Shock suspension system feels odd initially
Aesthetic might not appeal to everyone
Mechanics claim hydraulic disc brakes can be finicky to set up
Some buyers might be put-off by the non-traditional styling
Slight feeling of imbalance between front and rear compliance on very rough roads
The new Roubaix is something that has to be ridden to be believed
This Roubaix fit and felt like a race bike with the ride comfort of a mountain bike.
It’s a complete pleasure to ride.
The Roubaix behaves impeccably both on smooth tarmac and gravelly surfaces.
Specialized has breathed new life into the platform with hydraulic discs that let the Roubaix stop the way it rides: on any road, in any conditions, in a WorldTour-worthy package.

Are the Zertz inserts on the Specialized Roubaix SL4 a gimmick? We're not sure but it's one of the most comfortable bikes we've ridden.
Very comfortable
Same fork rake regardless of the size

While the pro peloton is only just starting to experiment with disc brakes, consumers have had access to road disc bikes for a few years. Specialized was an early adopter however a pure-bred race bike with disc brakes was missing from their catalogue until recently. In this review, CTech editor Matt Wikstrom compares
