Campagnolo's 12 speed Chorus Ultra-Torque crankset is compatible with disc and rim brake groupsets.
The new Chorus crankseset is directly moulded in without any surface coating and has an Ultra-Torque steel axle like the Record chainset.
The Chorus 12 speed cranks have a new bolt pcd of 123mm, giving it an extremely solid structure, also ensuring a wider variety of uses. The new smaller bolt circle on the Chorus chainset makes it compatible with 36/52, 34/50 and the brand new 32/48 ratio chainrings.
Available in 165mm, 170mm, 172.5mm and 175mm crank lengths.

Features and Benefits
The Q Factor remains the same (145.5): The widths and biodynamics of the stroke are the same.
Unidirectional carbon fibre cranks, steel axle and aluminium chainrings: Good stiffness and optimum power transmission.
Symmetrical teeth on the internal chainring: Fluid, precise transmission, even with extreme cross-chaining.
Optimised design for any chainring combination: Maximum performance, whatever the course style.
Double Fixing: Assembly of the large chainring on to 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.
Surface treatment of the chainrings for longer life
