• \n\t\t\t\tThe Q Factor remains the same (145.5): The widths and biodynamics of the stroke are the same.
\n\t\t\t
• \n\t\t\t\tUnidirectional carbon fibre cranks, steel axle and aluminium chainrings: Good stiffness and optimum power transmission.
\n\t\t\t
• \n\t\t\t\tSymmetrical teeth on the internal chainring: Fluid, precise transmission, even with extreme cross-chaining.
\n\t\t\t
• \n\t\t\t\tOptimised design for any chainring combination: Maximum performance, whatever the course style.
\n\t\t\t
• \n\t\t\t\tDouble Fixing: Assembly of the large chainring onto the crank is secured by a ring of 123mm bolts, while the inner chainring is attached to the outer by way of 96mm pcd bolts.
\n\t\t\t
• \n\t\t\t\tSurface treatment of the chainrings for longer life
\n\t\t\t

\n\t\tSitting just below Record and Super Record but implementing the same technologies for range topping performance and reliability at all times for the rider.

\n\t\tThe Chorus groupset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fiber, it is produced directly molded without any surface coating and has an Ultra-Torque steel axle like the Record crankset. It is versatile thanks to its ring of 123 mm bolts that, while giving it an extreme-performance structure, also ensures a wider variety of use segments. Available with 165, 170, 172.5 and 175 mm cranks, the smaller ring of bolts on the Chorus crankset makes it compatible with 52/36, 50/34 chainrings and with the newer 48/32 crowns.

\n\t\t\t
• \n\t\t\t\tUltra-torque: This is considered the best-performance crankset spindle in terms of stiffness, low weight and efficiency of power transmission. Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.
