For years you had to choose between stiff & snappy or compliant & comfortable for a race-bike—that is until the new Roubaix. Featuring a completely Rider-First Engineered™ frame our Future Shock technology & a top-level build kit the S-Works Roubaix with Shimano Dura-Ace Di 2 is right at home at a local fondo a Saturday group ride or a cobbled road race. The frame is one of the lightest that weve ever made & its been constructed from our top-tier FACT 11r carbon fibre. Its stiffness levels are also off the charts & compared to the SL4 iteration of yesteryear youll experience a whole new faster & more efficient geometry. Through some engineering sorcery however weve managed to keep the same fit feel & position that weve all come to love from the SL4 & kept it consistent throughout the size-range due to our Rider-First Engineered™ construction. Of course youre probably thinking get on to the suspension thing up front. We call it Future Shock & essentially its a piston in the head tube with 20mm of travel. We developed this technology in partnership with McLaren Applied Technologies & the result of this are a host of drastic performance improvements namely in the vertical compliance department. Without giving a physics lecture we found that focusing on vertical compliance instead of fork splay meant that we could improve smoothness speed & comfort in one fell swoop. & of all the bikes that weve tested with our Rolling Efficiency Model the new Roubaix outperforms anything on the market. We specd our cobble-crushing S-Works frame with the legendary performance of the Shimano Dura-Ace 9150 Di 2 electronic build kit & 9170 hydraulic disc brakes a full assortment of S-Works bits & h&-built Roval CLX 32s with the legendary Ceramic Speed bearings & custom hubs. Add it all up & you get a race bike at heart with the technology to float over the roughest roads. Featuring our Rider-First Engineered™ design that ensures every frame size has the same legendary responsiveness & smooth ride quality that youd expect from a Roubaix. The S-Works FACT 11r frameset is our highest quality carbon frame offering the ideal blend of light overall weight & targeted stiffness while the all-new Future Shock suspension system at the cockpit delivers a revolutionary degree of comfort & control. An S-Works FACT Disc fork is built from our FACT carbon fibre for supreme stiffness strength & reactivity while a thru-axle design only stands to bolster all of the above. The Roval CLX 32 wheelset is the perfect balance of light weight durability & aerodynamics. Its stiff enough for sprinting strong enough for abuse & its Ceramic Speed bearings keep things silky-smooth making CLX 32 wheels the ultimate all-rounders.FRAMES-Works FACT 11r carbon Endurance Geometry Rider-First Engineered™ 12x 142mm thru-axle Future Shock suspension 20mm of travel flat disc mounts FORKS-Works FACT carbon 12x 100mm thru-axle FRONT WHEELRoval CLX 32 Disc Win Tunnel Engineered carbon rim 32mm depth Roval AFD Hub Ceramic Speed bearings 21h REAR WHEELRoval CLX 32 Disc Win Tunnel Engineered carbon rim 32mm depth Roval AFD Hub Ceramic Speed bearings 24h INNER TUBESStandard Presta valve FRONT TYRETurbo Cotton 700x 28mm REAR TYRETurbo Cotton 700x 28mm CRANKSETS-Works FACT Carbon CHAINRINGSCarbon fiber spider 50/34TBOTTOM BRACKETOSBB Ceramic Speed bearings SHIFT LEVERSShimano Dura-Ace Di 2 Disc 9170FRONT DERAILLEURShimano Dura-Ace Di 2 9150 braze-on REAR DERAILLEURShimano Dura-Ace Di 2 9150 11-speed CASSETTEShimano Dura-Ace 9100 11-speed 11-30t CHAINShimano Dura-Ace 11-speed FRONT BRAKEShimano Dura-Ace Di 2 9170 hydraulic disc REAR BRAKEShimano Dura-Ace Di 2 9170 hydraulic disc HANDLEBARSS-Works Carbon Hover Drop 125x 75mm TAPES-Wrap w/ Sticky gel STEMS-Works SL alloy titanium bolts 6-degree rise SADDLES-Works Phenom GT 143mm carbon rails EVA foam carbon base SEATPOSTSpecialized CG-R FACT carbon single-bolt 27.2mm PEDALSNylon 105x 78x 28mm loose balls w/ reflectors ...

With six wins at Paris-Roubaix our Roubaix has proven that Smoother is Faster. Until this moment however smooth has admittedly come with some compromises. But not anymore. The all-new S-Works Roubaix now delivers compliance without compromise by introducing a radical new Future Shock 2.0 that gives you more control & damping options a new Pave seatpost that creates our most balanced Roubaix to date aerodynamics that equal the Tarmac & a Rider-First Engineered™ frame that tips the scales below 900 grams (
Size: 56cm Black). Is it still comfortable? Sure but don’t call it a comfort bike because performance was behind every engineering decision we made. This is the new Roubaix. Of course this also frame

Includes:: our revolutionary all-new Pave seatpost to ensure that your ride is perfectly balanced & comfortable. The new frame delivers compliance without compromise via the perfect balance of aerodynamics light overall weight compliance & Rider-First Engineering™. With tube shapes that were born in our Free Foil Shape Library & validated in the Win Tunnel the new Roubaix’s as aero as the Tarmac SL6. Meanwhile to ensure the weight & ride quality we turned to a Rider-First Engineered™ design to deliver optimal stiffness & compliance across all sizes from 44 to 64cm. Of course the frame also stays below 900 grams (Size 56cm Black). & to prep you for your own Hell of the North we’ve made room for 33mm tires. To go along with the new frame we’ve also developed a totally-new S-Works Pave seatpost. Not only is it the first compliant seatpost that’s ALSO aerodynamic it does so without any additional weight or finicky contraptions. Starting with the same D-shape design found on the Tarmac we took its compliance a step further by building additional flex into the upper & developing a new drop-clamp design in the frame. This provides plenty of compliance while staying perfectly balanced with the front-end so you get a smooth balanced ride no matter how rough the road. The Future Shock 2.0 is the result of our pro riders’ demands for the cobbles of Roubaix. It’s smoother faster & gives you more control via a knob atop the stem. This knob adjusts compression from fully-open to stiff while hydraulically-damped internals control rebound. Add it up & this latest version will reduce fatigue & increase your speed no matter the terrain. The new Smooth Boot top cap & Future Stem also enhance the aesthetic so you get a clean transition from head tube to stem.
