The Major Jake is the perfect bike for the serious racer that is still looking for something they can take on long cross-training rides. Kerry Werner and Rebecca Fahringer both rode it to numerous podiums during the 2019 CX season. A full carbon frame and fork make light work of climbs and punchy, steep obstacles. 700x33c Maxxis All Terrane tires, SRAM Rival 1x drivetrain, comfy Velo Shock-Proof bar tape, and hydraulic disc brakes make this bike race-ready right out of the box. Kona Carbon Designed to be lightweight and built to demanding standards. Carbon fiber has long been praised for its weight and strength, but rather than chase grams, we place our efforts on the performance that is possible when the right high-modulus fibers are in the right places. Our designers work very closely with our manufacturer to ensure there is no compromise to the desired ride characteristics, durability, and—finally—weight stipulations that we expect from our bikes. Internal Headset Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. Tapered Head Tube More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it's needed. Tubeless Compatible Rims Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems. 12x142mm Axle 12x142mm, 12x148, and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer dimension of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted.
Ready to build your dream 'cross bike? Boone Disc frameset is built with ultralight 600 Series OCLV Carbon. It features a cyclocross-specific geometry, Front and Rear IsoSpeed to smooth rough courses, and front and rear 12mm thru axle dropouts for better stiffness and handling. It's right for you if... You're lining up every weekend to race, and you're looking to build up a lightweight cyclocross bike (or a really sweet pit bike) so you can spend more time doing what you love: getting muddy and winning races. The tech you get An ultralight 600 Series OCLV Carbon frame with Front and Rear IsoSpeed, integrated cartridge bearing headset, and Control Freak cable management. Designed for 12mm thru axles and flat mount disc brakes. The final word There are a lot of carbon cyclocross frames out there, but there's only one with both Front and Rear IsoSpeed. Boone soaks up the fatiguing bumps in a 'cross course so you'll stay stronger longer and have enough energy after your race to party. Why you'll love it - This bike was designed with input from cyclocross royalty, including World Champion Sven Nys and U.S. National Champ Katie Compton - Carbon rules on the cross course—it's lighter, more forgiving, and more efficient than aluminum - The combination of Front and Rear IsoSpeed cuts down on the fatiguing impacts of rough courses and increases compliance, giving you more traction when it matters - Boone's cross-specific geometry and tube shapes make shouldering easy so you can dominate all aspects of a race, including run-ups
