The Unit X has become a cult favorite among die-hard Kona fans. Maybe it’s the Cromoly frame. Maybe it’s the fact that it’s a bikepacking monster, or its well-geared 12-speed drivetrain, or modular dropouts which give you the ability to run it as a single speed if that’s your thing. Maybe it’s because the rigid fork makes it that much more of a classic. We may never know why the Unit X is such a popular bike, but we can only guess it’s because it is one of the most practical machines in our lineup.
“The Unit X is a perfect gateway drug for new riders to experience all types of riding.” - Adventure Cycling
