When called to arms, the multi-classic winning ROUBAIX reacts as though simply an extension of mind and body. Pros like Tom Boonen—who rode his Roubaix to a record equaling 4th Paris-Roubaix victory this year—count on its smooth ride and responsive handling to get the job done. With size-specific engineering and a frame that delivers the best balance of vertical compliance, low weight, and torsional stiffness, riders of all sizes can experience the same ride quality and performance as Boonen.

WHAT Performance-optimized frame design featuring innovative structures like our proprietary one-piece OSBB/chainstay, internal ribbing, and hollow carbon dropouts and headset cups (SL3 frames only).
WHY Optimizes weight and stiffness in every part of the frame for greater acceleration, efficiency, and handling.
HOW The one-piece OSBB/chainstay design resists deflection under extreme pedal loads for improved power transfer. Internally raised ribs at the BB and head tube use optimized fiber alignment to increase stiffness. And hollow dropouts and headset cups cut weight to a minimum.
SHAPED SEATSTAYS AND
NEW COBL GOBL-R
WHAT Engineered seatstays (all-frames) and our newly designed COBL GOBL-R (S-Works only) work to sharpen handling and damp road vibration.
WHY Seatstay shaping with molded Zertz increases
rear-end compliance and mutes vibration,
while the COBL GOBL-R further enhances compliance over rough surfaces, minimizing rider fatigue.
HOW Redesigned, more triangulated seatstays have straighter lines from seat tube to dropout. This better engineered structure increases lateral stiffness while maintaining vertical compliance. The unique COBL GOBL-R design absorbs vibration for a smoother, more compliant ride.
SIZE-SPECIFIC ENGINEERING: FORK
WHAT More compliant and lighter fork with size-specific crown sizes (1-1/8”, 1-1/4” and 1-3/8”).
WHY Creates a more balanced and stable ride for riders of different sizes.
HOW Better layup and size-specific bearings means the fork is 20% more compliant and 30g lighter overall.
HYPERBOLIC SHAPED HEAD TUBE
WHAT Strategic surface shaping of the head tube/top tube/down tube junction, designed to optimize specific ride characteristics.
WHY Improves torsional stiffness by creating a more direct connection to the front wheel through the steer tube, while maintaining compliance.
HOW By manipulating the geometry of this junction, we make gains in stiffness without having to use an overly stiff fiber that would sacrifice vertical compliance. Widening the top tube and down tube eliminates flat spots behind the head tube for greater frame stiffness.
SIZE-SPECIFIC ENGINEERING: FRAME
WHAT Size-optimized frame engineering.
WHY To ensure riders of all sizes experience the same sharp, smooth handling attributes and enjoy the ride quality and performance Roubaix is known for.
HOW Size-specific tube diameters, seatstay angles, and carbon fiber layup change as you go up in frame size.
