Kona Unit
The Unit has garnered a cult following among serious bikepackers. The love for fully-rigid steel is real. Still made with Reynolds Cromoly, the 2020 Unit is getting a facelift and a shiny new set of 29” boost wheels with thru-axles to help conquer rougher terrain. We’ve spec’d the Unit as a single-speed but its full-length freehub body allows for gears and the dropout has a derailleur hanger, should you want to modify your setup. Updated geometry provides better handling and a more comfortable ride, so you can get lost on those backwoods adventures!
COLOR: Matt Black w/ Sage & Charcoal Decals

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, 12×148 and 12×157 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 12×148 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 12×142 thru-axle.

The original owner shall pay all labor charges connected with the repair or replacement of all parts.

When warranty on non-carbon Kona bikes and frames is NOT registered within three months of purchase, Kona warrants to the original owner that the frame of this new Kona bicycle purchased from an authorized Kona dealer shall be free of defective materials or workmanship for a three-year period. IF THE WARRANTY IS REGISTERED WITH KONA WITHIN THREE MONTHS AFTER THE PURCHASE OF THE BICYCLE, THE WARRANTY IS EXTENDED FOR THE LIFETIME OF THE ORIGINAL OWNER, with the exception of carbon bikes and frames. During warranty period, Kona shall repair or replace, at its sole option, the bicycle frame if Kona determines the frame is defective and subject to this limited warranty. The original owner shall pay all labor and shipping charges connected with the repair or replacement of the bicycle frame.
