The Mondraker Kaoz Dirt Jump Frameset provides the perfect foundation for building a custom dirt jump bike, combining distinctive Mondraker styling with precision-engineered aluminium construction. Designed for riders who want to express themselves on dirt jumps, pump tracks and skateparks, the Kaoz features a Stealth Alloy Evo frame manufactured from 6061 T6 aluminium with variable-thickness hydroformed tubing. Its compact 26-inch Forward Geometry delivers responsive handling and manoeuvrability, allowing riders to carve through transitions, generate speed over rollers and confidently approach challenging jumps. Whether creating a dedicated dirt jump machine or upgrading an existing setup, the Kaoz Frameset offers a durable and capable platform for creative riding.
Strength and stiffness are central to the Kaoz's design, with a distinctive reinforced section behind the head tube providing additional structural support and reducing unwanted flex during demanding manoeuvres. The unique split-forged bottom bracket shell uses a two-piece construction to improve lateral stiffness and distribute the forces generated during hard compressions and landings. By maintaining a continuous structural transition towards the chainstays, the design helps minimise stress concentrations and improve fatigue resistance. The frame's carefully considered construction provides precise steering response and dependable durability, helping riders maintain control when progressing their skills on technical jump lines and skatepark features.
Designed around a simple and reliable single-speed drivetrain, the Kaoz Frameset features adjustable sliding dropouts with an integrated chain tensioning system and rear brake mount. This allows riders to adjust chain tension and brake caliper positioning together, maintaining correct alignment without additional brake adjustments. An oversized tensioner dial makes fine-tuning straightforward, while Mondraker's Silent Core internal cable routing helps eliminate unwanted cable noise during jumps and landings. The frame accommodates a 26-inch wheel setup, a BSA 73mm bottom bracket and a 10x135mm rear axle arrangement, providing a practical starting point for a personalised build. Available in Medium and Large sizes, the Kaoz Frameset combines purposeful geometry, robust construction and thoughtful details for riders looking to create their ideal dirt jump bike.
