Campagnolo is all about drivetrain evolution, and their Chorus Crankset proves it. The full-carbon cranks and 4-arm spider feature a unified bolt pattern that allows for all three chainring standards. This design incorporates an 8-bolt pattern with a spider arm that not only holds the chainring in place by way of the bolt, but also supports the chainring to increase system rigidity. The crank arms and spider are hollow for maximum stiffness and minimal weight. The integrated Ultra-Torque spindle joins the crankset together via a toothed Hirth joint in the center. - Chainring BCD: Campagnolo 146 Asymmetric, Campagnolo 112 Asymmetric

Campagnolo's incredible Record Ultra-Torque Crankset sports a unique, integrated spindle that joins the two sides of the crankset together via a toothed Hirth joint in the center.

Plus, the Super Record chainrings sport special pins and plating for fast, silent shifts and long life. - Chainrings included: Yes - Drivetrain speeds: 11 - Number of chainrings: Double - Spindle interface type: Campagnolo Ultra-Torque

The design of the four arm carbon fiber cranksets that so well identify the Super Record, Record and Chorus groupsets has also found its way into the fantastic Campagnolo Potenza 11 drivetrain, albeit in an aluminum construction. The Potenza crankset is made with both left and right crank arms in hollow forged aluminum to keep weight to a minimum while maintaining the same performance characteristics of its carbon fiber counterparts. Potenza’s four arm spider design makes for one single crankarm for all chainring options thanks to its unified bolt pattern which allows for all three chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankset. Changing between compact and standard with the Potenza groupset is as easy as changing eight bolts and two chainrings. While the 4-arm bolt pattern offers advantages in terms of practicality, the Campy Tech Lab designed it primarily with performance characteristics in mind. The eight bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity to the point of surpassing its direct competitors in laboratory tests. -Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings -Power-Torque system have drive-side bearing pre-installed. The non-drive bearing comes pre-installed in the bottom bracket cup -Power-Torque Plus system utilizes a self extracting crank bolt for easy disassembly -Requires use of Power-Torque bottom bracket cups -Features Campagnolo X.P.S.S.

Many top features are packed into the Centaur crankset. The four-arm design allows for independent bolt circles, offering greater stiffness and structural integrity, and also provides additional versatility, as a single crankset is compatible with both standard compact and semi-compact chainrings. Add these features to the first aluminium crankset with an Ultra-Torque axle and the result is a component that is very similar to the top-of-the range part. - Requires use of Ultra-Torque bottom bracket cups-Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings - Ultra-Torque axles couple together in the middle of the BB shell via a Hirth Joint that self centers the crank. This results in a very light weight and stiff system that transfers power to the pedals without power loss - Features Campagnolo X.P.S.S. (eXtreme Performance Shifting System) featuring geometrically optimized chainring teeth. Optimized when mated to a full Campagnolo drivetrain - Ultra-Torque system have both drive and non-drive side bearings pre-installed
