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. (eXtreme Performance Shifting System) featuring geometrically optimized chainring teeth. Optimized when mated to a full Campagnolo drivetrain -Power-Torque system uses a single piece axle fixed to the drive-side crank arm which allows for simplicity and a light weight and rigid axle
