Campagnolo Record X Crank - Carbon | Ultra Torque | 1x13-speed

Record 13 – From The Same Stone

The relationship between material and intention has shaped Italian craftsmanship for centuries. Just as stone gives Italy’s cities and roads their architecture and structure, the Record 13 platform, in keeping with this philosophy, defines a new generation of performance. Building on the technical foundation of the 13-speed drivetrain components introduced with the Super Record series, Campagnolo is expanding its portfolio to reach a wider range of athletes. However, the core aspects remain unchanged: fast and precise shifting, consistent braking control and seamless electronic integration. And all of this is tailored to the entire spectrum of modern cycling: road bike, all-road and gravel. Three disciplines. One vision.

Campagnolo Record X crank

With its structural stiffness, mechanical efficiency and functional aerodynamics, the crank from the Record X series forms the beating heart of a modular drivetrain system that delivers top performance on any gravel terrain and under all conditions. Added to this are a low weight and the unmistakable aesthetics for which Campagnolo is known. By the use of visible carbon, the crank arms not only reflect the iconic design but also offer a precise ergonomic and biomechanical fit thanks to various lengths available. The exterior appearance is rounded out by the special “Record X” branding which embodies both the attention to detail and the craftsmanship of the brand from Vicenza.

Firmly connected to the crank arms are the proven Ultra-Torque half-shafts which ensure more direct power transmission, thereby minimizing energy loss and maximizing efficiency. In addition, the length of the ASTM2-certified steel half-shafts has been revised (47.5 mm chain line with a 152 mm Q-factor) to optimize compatibility with gravel frames and provide greater tire clearance. Also the wide range of chainring options from 38 to 52 teeth (Aero, not included), is designed to cover virtually every style of gravel sports, from adventure to professional high-speed racing.

Features of the Record X crank:

• lightweight and elegant: high-quality crankarms made of UD carbon fiber
• durability and maximum stiffness for optimal power transmission: durable Ultra Torque™ steel crankshaft (ASTM2-certified)
• dimensions optimized for gravel frames: 47.5 mm chain line and 152 mm Q-factor
• modular design and compatibility with a wide variety of chainrings
• weight: approx. 687 g (172.5 mm, with Aero chainring, 40 teeth; manufacturer information)

Ultra Torque™ | The system, which uses two shaft halves that are inseparably connected to the respective crank arm, has nothing to fear from a comparison with an integral crankshaft in terms of torque transmission. A single oversize bolt ensures a firm connection, which also facilitates assembly. A larger diameter and the bearings located outside the bottom bracket shell, which allow for an increased support width, also make the entire construction stiffer. The Hirth spur gearing, which originates from engine construction, also benefits torsional rigidity and gives the Ultra Torque™ crankshaft self-aligning properties.

Scope of supply:

1 pair of crank arms with integrated half shafts (without chainring and bottom bracket)

Important note: Compatible exclusively with QCK-Tech bottom bracket cups.
