Kona
Process X DHStandard
The Process X DH is Kona’s gravity-specific interpretation of its aluminum Process X platform, aimed squarely at bike-park laps, shuttle runs, and riders who want a dual-crown bike without stepping into a full World Cup-style downhill chassis. It uses a 6061 butted aluminum frame with 162mm of rear travel, paired from the factory with a 190mm RockShox Boxxer and a coil shock. That configuration, along with Kona’s stated use of a linkage-driven single-pivot layout with a progressive leverage curve and low anti-squat, makes the bike’s priorities clear: descending composure, consistency on repeated hits, and mechanical simplicity over pedaling efficiency.
What distinguishes this generation is how closely it ties a park-focused DH build to a more versatile modern enduro platform. The frame adopts SRAM’s UDH standard, uses external cable routing for easier service, and includes under-top-tube mounts for tools or spares—practical details that matter for riders who spend a lot of time maintaining and lapping the bike. Kona also built in a flip-chip at the seatstay/rocker junction to accommodate either a 29-inch or 27.5-inch rear wheel while keeping geometry changes controlled; the stock bike is delivered as a mullet. In the market, that places the Process X DH as a relatively accessible, purpose-built gravity bike for riders who want park-bike toughness and dual-crown confidence, but with more adaptability and less specialization than a pure race downhill bike.

Geometry & fit.
4 sizes published.
The geometry points to a stable, descending-first bike with modern long-front-center proportions. Across the size range, the head tube angle is 63.5 degrees, which is firmly in gravity-bike territory and should deliver strong composure at speed and on steeper tracks. Reach numbers of 440mm (S), 465mm (M), 490mm (L), and 525mm (XL) are contemporary and roomy, giving riders space to stay centered without making the bike unusually stretched by current park-bike standards. Chainstays are a fixed 440mm in every size, and wheelbase grows from 1221mm in S to 1316mm in XL, reinforcing the bike’s emphasis on stability and predictable tracking.
The steep effective seat tube angle of roughly 77.8 to 77.9 degrees is notable on a DH-oriented build, though on this bike it is more about keeping rider position sensible on transitions and occasional pedaling than making it a true all-day climber. Stack sits between 632mm and 641mm depending on size, which should give the cockpit a fairly tall, confident feel when standing on steep descents. A 20mm BB drop keeps the center of gravity reasonably low without going to extremes that could make pedal or crank clearance more problematic in rough terrain. Overall, the numbers suggest a bike that should feel planted and forgiving at speed, with mullet-wheel agility and enough front-center length to suit aggressive riders in park and shuttle environments.

The lineup.
1 build, ranging $3,399.
The available lineup is straightforward: Kona offers the Process X DH in a single Standard build at $3,399. That one-build approach makes this a notably direct value proposition in a category where dual-crown bikes can become expensive quickly. The key elements are the ones that define the bike’s intended use: a 190mm RockShox Boxxer dual-crown fork, a coil rear shock, and the 162mm aluminum Process X DH frame configured as a mullet.
Because there are no alternate trims listed, the emphasis here is less about choosing between component tiers and more about whether the stock package matches the rider’s intended use. The spec choices prioritize gravity performance and durability rather than lightweight parts or broad versatility. Combined with features like UDH compatibility, external routing, and the wheel-size flip-chip, the Standard build reads as a practical, park-ready package rather than a highly stratified model range.
