The smoother, faster Roubaix—named after the gruelling Paris-Roubaix race it has won three consecutive times—is a high-performance, endurance-focused bike that’s highly stable and efficient. Shimano 10-speed compact gearing and our new DT-Axis 2.0 wheels improve efficiency over any terrain.
FACT 8r carbon, FACT IS constructed frame with Endurance Road geometry, Zertz inserts and tapered head tube for the perfect blend of stiffness, compliance and light weight
Ultralight FACT carbon monocoque fork with vibration-damping Zertz inserts is stiff, responsive, and durable
Significantly lighter than comparable-level wheelsets, these tough new DT-Axis 2.0 hoops roll smooth and fast
Adjustable four-position oversized alloy stem with 31.8mm bar clamp for strength and versatile positioning
Specialized Comp shallow drop alloy bar for serious performance and ergonomic position
New, 10-speed Shimano Tiagra STI shifters are renowned for their race-ready performance and exceptional value
Minimalist, high-performance BG Toupe Plus Sport saddle is ultralight with a flat profile and generous padding for long rides and explosive efforts
Features
Hyperbolic Shaped Head Tube
What? Strategic surface shaping of the head tube/top tube/down tube junction, designed to optimise 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 fibre that would sacrifice vertical compliance. Widening the top tube and down tube eliminates flat spots behind the head tube for greater frame stiffness
Fact is Construction
What? Performance-optimised 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? Optimises 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 optimised fibre 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, minimising 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 - Frame
What? Size-optimised 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 fibre layup change as you go up in frame size
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
