Hei Hei G10

Kona keeps the Hei Hei lineup exceptionally streamlined, offering just two complete builds alongside a standalone carbon frameset. Both complete bikes utilize mechanical SRAM drivetrains, a deliberate choice that prioritizes long-term reliability, lower replacement costs, and ease of maintenance over the complexity of electronic shifting.

The flagship CR G10 build is anchored by a premium RockShox suspension package, pairing a highly tunable Pike Ultimate fork with a Deluxe Ultimate rear shock. This top-tier damping is a major value add, elevating the bike's descending capability far beyond typical cross-country expectations. The drivetrain features SRAM's Eagle 90 mechanical transmission, while stopping duties are handled by SRAM Motive Bronze four-piston brakes. Rolling stock consists of WTB KOM Team i30 rims laced to DT Swiss 370 hubs, wrapped in aggressive Maxxis Dissector tires that favor cornering grip over pure rolling speed.

The more accessible G10 build swaps the carbon frame for aluminum and steps down to Fox Rhythm suspension. It utilizes a SRAM Eagle 70 mechanical drivetrain but retains the same dependable Motive Bronze four-piston brakes and Maxxis Dissector tires. Across both models, the component selection clearly favors durability and trail-ready performance over weight savings, resulting in complete bikes that hover just over the 30-pound mark.

Reviewers consistently characterize the Hei Hei as a highly capable endurance machine that trades a bit of climbing speed for significant descending composure. The transition to the new Swinger suspension layout is widely praised for its plush, active feel. On technical ascents, the rear wheel maintains excellent grip, providing "velcro traction on the ups" (Theradavist) to help riders clean rooty, awkward sections. While the active suspension does exhibit some pedal bob on smooth fire roads when left fully open, engaging the shock's lockout quickly firms up the platform for efficient power transfer.

When pointed downhill, the bike feels remarkably stable for its travel bracket. The longer wheelbase and robust suspension allow it to remain "composed while blasting through rough sections" (NSMB), though testers note it will eventually find its limit in high-speed, jarring rock gardens where a true enduro bike would plow through. Despite this stability, the relatively short rear end keeps the handling dynamic, making the bike "easy to flick around and maneuver in tight corners" (Blisterreview).

The consensus points to a low-fatigue ride quality that excels on multi-day trips and long backcountry loops. While its overall weight puts it at a disadvantage against dedicated cross-country race bikes on smooth climbs, the Hei Hei ultimately "gives the impression of a larger trail bike" (Bikepacking) while retaining the efficiency needed to cover massive distances.
