Simply put, Oiz is the fastest XC bike to leave our factory in over 180 years.

ALL SEASON EVOLUTION Balanced weight distribution for maximum traction and a powerful pedaling position keep the Bigfoot S 1 charging forward all year. The redesigned Bigfoot elevates fat bike performance to downright fun, anywhere, anytime. The confident, aggressive handling tracks precisely where you want on a descent or technical trail, and the simple one-by drivetrain offers reliable, simple shifts with gloved hands. With maximum traction in the most extreme riding conditions imaginable, Bigfoot claws its way up, and the finely tuned steering geometry and massive tires provide confident, aggressive handling to rip back down. The Bigfoot excels in all-season weather and extreme terrain to make every ride big fun. PROGRESSIVE DESIGN Built from the powder-up with our holistic approach to fit & geometry. A combination of longer reach, slack head tube angle and steep seat tube angle gives every Bigfoot a powerful pedal position, increased climbing traction and added control when descending. FAT’S WHERE IT’S AT 75mm wide 27.5” rims and frame clearance for up to 4.6" tires to put more rubber onto whatever surface you're riding and allow for lower pressures and greater traction. FRAME FEATURES Evolved, thoughtful details make it even better. Generous standover clearance and extra stiffness provided by 12x197mm thru-axles and internally routed cables make the Bigfoot’s aluminum frame ideal for extreme terrain. WINTER RIDER Optimized for the cold, capable year-round. All models feature disc brakes with DOT fluid or cable actuation for consistent performance over varying temperatures. When included, dropper posts are spec’d for reliable cold weather performance. MULTI-FUNCTIONAL Frame details add versatility. Rack mounts in the rear, bottle mounts above and beneath the down tube and triple mounts on the fork give you the option of running a barebones setup or loading up for a massive excursion. STANDOVER HEIGHT Top tube clearance is critical in fat biking. Getting off the pedals in deep snow requires lots of space over the top tube. Bigfoot strikes a perfect balance between max clearance and making space for a frame bag in the front triangle.

Whether you're ripping fast flowy singletrack, putting the power down on punchy climbs, or tearing the tires off in the corners, the Optic continues to push the boundaries of what's possible on a short travel trail bike. The new Optic with 140mm/125mm of travel condenses years of technology from our long travel bikes into a lightweight package that's as ready to tear up climbs as it is tackling challenging descents. The VPSHP suspension layout provides increased rearward axle path and an idler to manage pedal feedback, keeping Optic's playful roots, while punching above its weight when the trails get rough. Available with a 27.5" rear wheel (MX), as well as 29" in some markets. Swapping the linkarm and lower shock mount with the "Missing Link Kit" converts between 27.5" and 29" to let you pick the wheelsize that suits you best, while maintaining geometry and kinematics to ensure consistent fit and bike setup. - Carbon front triangle, seatstay and chainstay, 125mm of travel, threaded BB. - Ride Aligned with Norco design kinematic, High pivot Horst Link and non-concentric idler. - 29"/27.5" (with the option to change to 29") with no compromise geometry and kinematics. - RockShox Lyrik Select+ fork and Vivid2 Select+ shock. - Weight (S3): 15 kg / 34.1 lbs - Ride AlignedTM – Perfect fit, dialed handling and personalized setup in minutes. - No Other Way Limited Lifetime Warranty

Beyond the Expected. Revolver 130 sets the bar for what a Cross-Country bike can do. With 130 mm of front travel and 120 mm at the rear, it's fast, efficient, and capable. The Revolver is the lightest full-suspension frame Norco has ever built, with a surprising amount of capability. At the core of its efficiency is our advanced approach to a Flex-Pivot suspension design. With aggressive XC geometry and a carbon frame layup optimized for each frame size to enhance stiffness and compliance, Revolver maintains consistent kinematic and weight distribution across all sizes. It's a strong foundation for any rider to drive up and charge down, beyond the expected. Quick and snappy on acceleration, whether you're going up or ready to rip down, its suspension performance is well beyond what you can expect from a shorter travel bike. Head out for epic days, attack climbs, and crush descents, while cruising through the singletrack; it's the best choice for stage races or all-day adventures. SUSPENSION TRAVEL Precision and control for all-day efficiency. 130 mm of travel in the front and 120 mm of travel in the rear delivers lightweight, precise, efficiency whether you’re sprinting out of the saddle or holding your line on a rough descent. FLEX-PIVOT SUSPENSION At the core of its efficiency is Norco’s advanced approach to Flex-Pivot suspension design. This suspension layout gives us improved performance out of the lightweight, inline XC air shocks we're spec'ing that rivals the suspension sensitivity that would typically be reserved only for heavier and larger volume air shocks. Combined with consistent anti-squat and carefully tuned leverage curve progression, this platform gives Revolver an excellent balance of efficiency and technical capability. PERFORMANCE TUNED SUSPENSION Customized suspension development to support Revolver's best attributes. Done right, an XC bike doesn’t need a firm compression tune to feel efficient. For the Revolver 130, we worked with RockShox on a SIDLuxe tune with custom machined internals that improve shock sensitivity and enhance your ride through technical terrain. All this involving hours in the lab and endless laps on trail before we were satisfied, so that you can achieve optimal support, power transfer, and ride feel, wherever you ride. LIGHT AND DURABLE A lightweight frame that encourages putting the hammer down. 450g lighter than the previous generation, Revolver 130 is more than ready for the demands of the rowdiest cross country racing. The raw or tinted clear coat paint is half the weight of standard paint, while titanium hardware, compact double-row Enduro bearings, and compact links enhance durability and precision. GEO TO MEET MODERN XC DEMANDS Consistent weight distribution across all sizes. The Revolver 130 has a 66.5-degree headtube angle and seat tube angles that steepen per frame size. Stabilized rear centres also grow per size, for balanced weight distribution and a confident ride across sizing. The frame carbon layup was optimized per frame size for stiffness and compliance, giving you a strong foundation for driving up and charging down. Size 2–Size 5 frames accommodate two water bottles, and all sizes feature long dropper post compatibility for maximum descending capability. SIMPLIFIED MAINTENANCE Keeping your bike out of the shop and on the trails. Internal cable guide tubes offer easy cable routing and no headset cable routing complication. An industry standard threaded bottom bracket was used for easy maintenance and frames offer UDH compatibility for the new universal derailleur hanger. Revolver also comes with an ISCG05 chainguide mount, giving riders the option to fit a small chainguide onto the frame. RIDE ALIGNED™ Setup like a pro. Our industry-leading Ride Aligned™ Setup Guide is all about creating the best rider experience. Using a simple and incredibly precise process, it tunes your unique settings based on your body makeup and the way you ride. NO OTHER WAY LIMITED LIFETIME WARRANTY Revolver’s durable frame design, hardware and component decisions have been made specifically to keep you on the trail for longer. Accidents can happen, and when they do, our No Other Way Limited Lifetime Guarantee is our promise to get you back on the trail as soon as possible.

As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It's shown people the light of how high-volume, large-diameter tires can vastly improve the ride experience. It's also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level.
