Kona Major Jake 2021 - Cyclocross Bike
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.
Key Features:
- 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 diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017, you’ll see the 12x148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle.
Occasionally, without notice, manufacturers change product design and/or specifications.
