The Campagnolo Chorus 2x12-speed crankset is a true concentrate of consists of state of the art technology and versatility.
Technically advanced, thanks to unidirectional construction technology. The carbon fibre, is produced in a direct mold without any surface coating and features an Ultra-Torque steel spindle like the Record crankset. It is versatile thanks to its bolt circle diameter of 123 mm, while giving it an extreme-performance structure, also ensures a greater variety of applications. The smaller BCD on the Chorus crankset makes it compatible with 52/36, 50/34 and with 48/32T chainrings.
FEATURES
The Q Factor remains the same (145.5mm) - The widths and biodynamics of the stroke are the same.
Ultra-Torque axle - Pressure on the pedals is transmitted efficiently without any power loss.
Differentiated number of pins depending on the chainring combination - Constantly optimum engagement of the chain. Maximum shifting efficiency.
Double bolt circle diameter - Assembly of the large chainring on the crank is guaranteed by a bolt circle diameter of 123 mm, while the inner chainring will be mounted directly on the outer on 96mm BCD.
Symmetrical teeth on the internal chainring - Smooth, precise transmission, even with extreme cross-chaining.
Compatibility
To ensure the functionality of the mechanical Super Record, Record and Chorus drivetrains, Campagnolo recommends to avoid the use of older components at shifting groups from 2015 on. A distinctive marking, a squared letter as in picture 3, helps recognizing actual shifting components. The letters of the corresponding parts (right Ergopower and rear derailleur / left Ergopower, derailleur, cups and crankset) should match.
