Discover the performance-focused design of the Chapter2 HURU Climbing Disc Brake Frameset – Maroon 1928, a premium carbon road bike frameset developed for cyclists who enjoy challenging climbs, technical descents, and demanding road rides. Inspired by the Māori word “HURU,” meaning “feather,” this frameset emphasises lightweight construction and carefully engineered performance. Built using TORAY® T1000, T800, and 3K directional carbon fibre, the HURU combines climbing-focused design with responsive handling and a distinctive Maroon 1928 finish. It provides an advanced foundation for riders looking to build a personalised, high-performance road bicycle.
Advanced Carbon Engineering
The Chapter2 HURU features a sophisticated carbon construction using more than 300 individual pieces of pre-preg carbon fibre carefully laid by hand into stainless steel moulds. Its combination of TORAY® T1000, T800, and 3K directional carbon is engineered to balance frame weight, stiffness, and riding comfort.
The high-modulus carbon used in the head tube is designed to support accurate steering and confident cornering, while the bottom bracket area is engineered to promote efficient power transfer. This combination makes the HURU an appealing option for riders who prioritise climbing efficiency, responsive acceleration, and precise handling on demanding road routes.
Lightweight Climbing Performance
Designed with climbing-focused road cycling in mind, the Chapter2 HURU aims to minimise unnecessary weight while maintaining the structural characteristics required for performance riding. The disc brake frame weighs approximately 819 g in size M, with a stated tolerance of ±3%, making it a compelling choice for cyclists building a lightweight road bike.
The frame's carefully developed construction supports riders tackling steep gradients, rolling terrain, and long mountain ascents. Actual complete-bike weight and climbing performance will depend on the selected components, wheels, tyres, and final build configuration.
Confident Descending and Responsive Handling
The HURU is engineered for both climbing and descending. Its frame design focuses on predictable steering and cornering performance, helping riders maintain control through changing road conditions and technical turns.
The pencil-thin seatstays merge into the seat tube and top tube junction, creating a distinctive frame profile while helping manage road vibrations. This design aims to balance responsive handling with controlled comfort during longer rides. Proper frame sizing, component setup, and professional assembly remain important for achieving the intended riding characteristics.
Disc Brake and Thru-Axle Compatibility
This version of the Chapter2 HURU is designed for disc brake applications and features flat-mount disc brake compatibility with specified thru-axle dimensions. The front axle specification is 12 x 100 mm, while the rear specification is 12 x 142 mm with an M12 x 1.5 mm thread.
The frame also supports a Press Fit BB86.5 bottom bracket standard and has specified tyre clearance of up to 28 mm. Always confirm wheel, tyre, brake, and drivetrain compatibility before purchasing components for your build.
Electronic Drivetrain Compatibility
The Chapter2 HURU supports compatible electronic shifting systems, including Shimano® Di2, SRAM® eTAP, and Campagnolo® EPS. Its design also accommodates the specified compatible electronic shifting battery systems, subject to the drivetrain manufacturer's requirements.
The 1-1/8-inch CHAPTER2 headset specification and reversible C2 TUMU 27.2 mm seatpost contribute to the frameset's component configuration. Verify all component standards and installation requirements before assembly.
