Description
Kona Process X DH Aluminum Downhill Bike
The Kona Process X DH is built for riders who live for steep lines, huge jumps, and aggressive downhill terrain. Designed with downhill enthusiasts in mind, this aluminum gravity bike combines a playful rear end with the stability needed to handle massive hits, rough bike park sections, and technical race-style descents.
The 162mm rear suspension platform, 190mm RockShox Boxxer fork, and modern downhill geometry create a bike that feels agile enough for whips and side hits while remaining composed when charging through the roughest terrain.
Built around a strong Kona 6061 aluminum frame, the Process X DH is the perfect machine for riders looking to spend full days in the bike park and push their downhill riding further.
