The 2x12-speed Chorus crankset is a true concentrate of technology and versatility.
Technically advanced thanks to unidirectional construction technology in carbon fiber, it is produced directly melded 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.
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 cheinring 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.
