Campagnolo Chorus Crankset
This carbon 11-speed crankset shares the dramatic 4-arm redesign of Record and Super Record. All three cranks use the new 112mm inner and 145mm outer bolt circle to achieve maximum stiffness and lightness. Like Super Record and Record, the integrated crank to chainring mounting system of the Chorus makes maintenance a little easier and shaves a few grams plus you can install compact, mid-compact and standard rings on the same crank arms. So if performance and value are what you are after in a Campy crankset, Chorus could be a very good choice.
The broad, four arm, carbon fiber spider/drive side crank arm is sculpted for maximum efficiency, but you will swear it is all about the art. Campy Tech Lab engineers used in depth analysis developed new profiles for the ring teeth that are specific to the placement of the power stroke and changed the angles of the ring to reflect how the chain rides up or down during shifting. Sophisticated ramps, pins and specific machining of individual teeth help to move the chain up and down guarantee maximum efficiency during shifting developed by working closely with professional teams.
The crank arms themselves are Ultra-Hollow carbon fiber constructions just like Record and SR. This hollow construction actually works to eliminate stress points while improving the weight to stiffness ratio.
Chorus cranks use the super smooth and well-proven Ultra-Torque mounting system where both crank side are held into place with a 10mm hex bolt and a super stout Hirth joint. This system makes installation and removal as easy as loosening or tightening one bolt. Friction fanatics appreciate how smooth the Ultra-Torque system truly is. Just spin an Ultra-Torque crankset installed without a chain to watch is spin virtually free of friction.
For the best functionality, Campagnolo recommends matching 2015 and newer shifters, derailleurs, bottom bracket cups and cranks. This newest generation of parts will feature a squared letter, which in the case of the cranks, is located on the inside of the chainrings.
