Designed to offer both performance and comfort, the G4X excels in providing stability and control across diverse off-road conditions.

Multiple riveted mounting points provide ample options for attaching bottle cages and accessories, supporting long-distance excursions and gear transport. Compatibility with electronic groupsets, including the SRAM UDH standard, further enhances the bike’s adaptability to modern drivetrain technologies.
