The number to count on—240 with Ratchet EXP. The new 240 is developed for riders with the most extreme ambitions. The latest version of the hub is equipped with the Ratchet EXP system to maximize reliability. The increased bearing distance increases bearing lifetime, the straight spring provides more direct engagement (which reduces wear), and a smaller number of parts not only makes maintenance easier, but also reduces weight.

Step up your pace with this innovation packed boot. The newly developed Carbon Loaded™ shell and anatomic cuff provide a super anatomic, close fit that maximizes precision and energy transmission.

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 7-speed drivetrain make it one of the lightest kids' bikes on the market.

Designed to withstand the elements and provide comfort on rugged trails, the Trailcross GTX Flat Shoe blends a durable, hiking-inspired build with a high friction Stealth Phantom rubber outsole. - Bike and Hike outsole: designed for grip at the toe and heel while maintaining a pedal platform under foot - Weather-friendly GTX (Gore-Tex) mesh upper for breathability and comfort - Textile-free and closed cell sockliner - Lace tuck on the middle of the tongue - Neoprene cuff keeps debris out - Non-marking Phantom Dotty outsole for grip on and off the bike - Midsole flex points allow flex while hiking but keep stiffness while on the pedal

It has a nominal outside diameter of 65mm. Use the 690-XXL facer with the 750.2 Centering Cone Adaptor and 789 Reamer or 790 Pilot when facing head tubes with internal diameters of 55.95–55.90mm.

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 bio-mechanical 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 adaptive fit zones to create a disappearing fit on the foot. - Based on data gathered from Retul 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 Retul 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).
