Rigid framed bikes are great to test your skills and give yourself a new challenge on the trails you love.
SRAM SX Eagle features a full range 12 speed cassette and great shifting performance.
Made with Reynolds 520 cromoly, a steel frame is durable and compliant for added comfort.
SRAM Level brakes have excellent stopping power and manage heat efficiently.
The Unit X has become a cult favorite among die-hard Kona fans. Maybe it’s the Cromoly frame. Maybe it’s the fact that it’s a bikepacking monster, or its SRAM SX Eagle 12-speed drivetrain, or modular dropouts which give you the ability to run it as a single speed if that’s your thing. Maybe it’s because the rigid fork makes it that much more of a classic. We may never know why the Unit X is such a popular bike, but we can only guess it’s because it is one of the most practical machines in our lineup.
REYNOLDS 520 CROMOLY
Reynolds 520 tubes are mandrel-butted for accurate profiles and available in a wide range of shapes. Weight savings from butting provides competitively priced, light framesets that are noticeably compliant on the road or the trail, and are guaranteed to last a lifetime.
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.
44mm HEAD TUBE
44mm oversized heatubes allow us to run tapered steerer forks by using a large external lower cup headset bearing. The larger diameter steerer tube adds considerable stiffness and will increase responsiveness to the front end, improving all-around performance.
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.
12x148mm 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.

Please note that our specifications may be impacted by manufacturer component substitution changes caused by high global demand for bikes and resulting supply chain issues in the bike industry. We recommend confirming the specifications with your local Evo Cycles showroom if you have any questions.
Bike Weight: Many brands strive to list the lowest possible weight, but in reality weight can vary based on frame size, finish, hardware and accessories. The most accurate way to determine any bike's weight is to have your local showroom weigh it for you.
Let us know if you think there is something we need to improve.
