Kona Unit Steel Hardtail Mountain Bike 2021

Its single-speed design and Chromoly frame make its simplicity shine and keep the moving parts long-lasting for those big excursions.

Gear mounts on the fork legs and several options for mounting water bottles mean you won't go without any of the necessary gear no matter where you're travelling.

Reynolds 520 Chromoly 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. 44mm Oversized Headtube By using a 44mm oversized headtube, Kona is able to run tapered steerer forks while 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.

12mm Thru Axles 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. Tubeless Compatible Rims Tubeless rims allow for tyres with more puncture resistance; the ability to run lower tyre pressure, which provides better tyre grip on the trail; lower rolling resistance; and weight savings over traditional tube and tyre systems.
