The S-Works Torch is the latest evolution of the winningest footwear in cycling. Using Body Geometry together with biomimicry, data science, and obsessive craftsmanship, we engineered a shoe so thoughtfully constructed that you’ll forget you’re wearing it. Leveraging data science, we refined every detail of the S-Works Torch’s upper for improved fit and performance. The BOA cable is shifted down and angled, preventing lift on the ball of the foot and delivering power-enhancing structure while eliminating unwanted pressure or pinching. Adaptive materials allow natural movement of the foot where needed for comfort, while data-driven zonal reinforcement keeps the foot secured for crisp power delivery and optimal efficiency. Guided by more than 100,000 foot scans from our RETÜL fit data, we recognized that both a standard and a wide carbon base plate would best serve the spectrum of human foot shapes. An internal I-Beam adds stiffness and strength, eliminating the need for additional bracing. The result is a 20-gram weight reduction, enhanced efficiency, and immediate power transfer. Following RETÜL biomechanical data, we created an asymmetric heel cup that supports natural knee alignment and delivers the positive hold riders love while enhancing comfort by accommodating more room for the Achilles heel. The S-Works Torch is scientifically crafted to disappear on your feet and off the front. - New upper features reinforcement in key zones while also offering fit zones to create a disappearing fit on the foot. - Based on data gathered from Retül foot scans, the new base plate is 4mm wider at the ball than the previous generation of S-Works 7 shoe. - By optimizing its construction, the new carbon plate is 20g lighter than the S-Works 7. An internal "I-Beam" ensures it maintains the same stiffness as the previous generation. - An updated last makes use of Retül data to better match the shape of riders' feet, sloping more towards the lateral side to give a snug, close-to-foot fit. - Asymmetrical heel counter supports the medial side while removing material from the lateral side, allowing for a lower collar. - Updated BOA cable routing improves lockdown while reducing pressure across anterior ankle ligaments. - Independent alloy BOA S3-Snap Fit System for on-the-fly micro-adjustment, backed by the BOA Guarantee. - Titanium alloy cleat nuts can rotate to position pedal/cleats 5mm rearward. Three-bolt cleat pattern fits all major road pedals. - Non-slip, replaceable heel tread with internally recessed screws for security. *** IMPORTANT FOR WIDE FIT*** the new base plate is 4mm wider than the standard width (8mm wider than S-Works 7).

Kids move fast, and grow faster. At times, it can seem like there's a small window for the perfect bike fit. The right bike for a young rider is a delicate balance between too small, too big, and a short-lived just right. If we're going to inspire the next generation of riders, we need to keep kids comfortably riding longer. The Jett is designed so that you'll never fear the growth spurts. We did our homework to understand how kids grow—spoiler alert, kids' arms and legs grow more rapidly than their torso. We took to the books and designed a bike with child-specific touch points that withstand the development of young riders. The Jett is uniquely adjustable, perfectly proportional, and child-liftable—they'll always be set to Jett. The Jett Multispeed features an adjustable handlebar that allows kids to fine tune reach as their arms grow. The 2-hole position cranks combined with longer seat tubes give plenty of flexibility to dial-in the optimal pedaling position. And what's more, we designed the frame and reviewed every component to make the Jett one of the lightest bikes on the market. You're going to have to beg them to get off this bike. - We designed the Jett Multispeed to be uniquely adjustable with 2-hole position cranks, adjustable handlebars, and longer seatposts so kids can dial-in the perfect riding position as they grow. - Every detail of the Jett Multispeed—including the 130mm Bridge saddle, narrower-diameter grips, and short-reach, tool-less adjustable brake levers—was informed by Retul data from a kids' research group to be perfectly proportional for young riders. - A lightweight bike is simply more fun and the Jett Multispeed's all-new A1 aluminum frame, alloy fork, Pathfinder tires, and 8-speed drivetrain make it one of the lightest kids' bikes on the market.

Riding your fat bike on ice just got even better with the redesigned Dillinger tread pattern and tubeless compatibility. Carefully positioned studs allow you to rail icy off-camber singletrack with confidence and control, while taller side lugs bring improved cornering in snowy conditions.

We do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to pre-mature casing wear and stud loss.

At a mere 150 grams, the S-Works EXOS are the lightest cycling shoes to ever come with a Boa® dial. And not only are they ridiculously light, but they still have all the features that are synonymous with the S-Works label. They’re still at that World Tour level, just ridiculously light. To get the weight down to the 150-gram mark without sacrificing power transfer, we implemented all the engineering bells and whistles we could think of. And when that wasn’t enough, we thought up some more. The carbon outsole was developed using an advanced form of Finite Element Analysis and pressure mapping to pull out material where it wasn’t needed. This allowed us to keep crazy-high stiffness numbers, too. For the uppers, we completely removed the heel counter. And with a little help from the space-grade Dyneema® mesh and some CubicTec reinforcement, the heel molds to the back of your foot, so nary a watt is wasted. Lastly, we developed a new Warp Sleeve vamp that let us get rid of the toe box, and this further cut down the weight and increased the comfort. Of course we couldn't do any of the above without including our coveted Body Geometry features, like the Longitudinal Arch, Varus Wedge, and Metatarsal Button. Each one of these features have been ergonomically designed and scientifically tested to not only boost power, but to also increase efficiency and to reduce the risk of injury. The S-Works EXOS are the lightest cycling shoes to ever have a Boa® dial—experience the feeling of lightness. - Body Geometry sole and footbed are ergonomically designed and scientifically tested to boost power, increase efficiency, and reduce the chance of injury by optimizing hip, knee, and foot alignment. - Our lightest FACT Powerline™ carbon plate maximizes power transfer: Stiffness Index 13.0 - A revolutionary Dyneema® Mesh allows us to achieve weight without sacrificing hold for the ultimate connection and comfort. - BOA IP1 Fit System for on-the-fly micro-adjustment, backed by the Boa Guarantee. - Titanium alloy cleat nuts can rotate to position pedal/cleats 5mm rearward. - Non-slip, replaceable heel tread with internally recessed screws for security. - Form Fit last with a Warp Sleeve vamp for the ultimate in connectivity, comfort, and speed. - Three-bolt cleat pattern fits all major road pedals. - Approximate weight: 140g (1/2 pair, Size 42)
