The Campagnolo Chorus 12-Speed Crankset features lightweight carbon crank arms, and is optimized for Campagnolo's Ultra-Torque crank system. - Utilizes Campagnolo's Ultra-Torque crank system to provide a very lightweight and stiff system that transfers power to the pedals without power loss - Directly molded unidirectional carbon fiber cranks, steel axle, and aluminum chainrings provide exceptional stiffness and optimum power transmission - Symmetrical teeth on the internal chainring allow for fluid and precise transmission, even with extreme cross-chaining - Chainrings are surface-treated for longer life - Q-Factor: 145.5mm - Design is optimized to run multiple chainring combinations - Number of Chainrings: Double - Chainline/Hub Compatibility: 130 Hubs, 135/142 Road Disc Hubs > 415 mm Chainstay - Spindle Interface Type: Campagnolo Ultra-Torque - Chainring BCD: 96 - Pedal Spindle: 9/16" - Crank Intended Use: Road - Drivetrain Speeds: 12 - BB Included: No - Weight: 686
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
The new Record 12x2 Speed crankset: a new hole-free design for the right-hand crank that optimizes aerodynamics. The new carbon fiber Record 12x2 Speed crankset with unidirectional finishing guarantees continuity with the finishing of the entire groupset, whilst maintaining the Ultra-Torque bracket system on the steel axle to ensure perfect transmission of power. The new Record 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters without affecting the Q factor that remains constant at 145.5 millimeters. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) enable reducing the weight through greater use of carbon fiber. There are eight fixing screws for increased structural stiffness. The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chainrings optimize performance when downshifting in dead spots.
Designed specifically for use with H11 groupsets. Full Carbon crank arms and spider are hollow for maximum stiffness and minimal weight. Utilizes USB ceramic ball bearings. Light weight hard anodized alloy chainrings and alloy chainring bolts. Utilizes Campagnolo's Ultra-Torque crank system. - 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 - USB ceramic bearings increase smoothness and decrease rolling resistance, weight and the need for maintenance. USB bearings are 50% smoother than standard Campagnolo bearings - Ultra-Torque system have both drive and non-drive side bearings pre-installed - Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings - Required for use with H11 Ergopower shift levers, the crank spider is shifted outward to adjust for 135 and 142mm hub spacing while maintaining the Q-Factor - Requires use of Ultra-Torque bottom bracket cups
The road steepens, but instead of slowing down, you push harder on the pedals and fly up the hill as all of your power turns into speed thanks to your Campagnolo Super Record Ultra-Torque Crankset. It sports a unique, integrated titanium spindle design that joins the two sides of the crankset together via a toothed Hirth joint in the center. And for ultra-smooth pedaling, the crankset comes with ceramic bottom-bracket bearings that fit into outboard cups (sold separately). The aesthetically arresting design provides incredible stiffness, while Campagnolo's unified BCD (145/112mm) allows for all 3 chainring standards. 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 new Super Record 12x2 Speed crankset: an intense concentration of innovation that results in the greatest possible stiffness and precision in derailing, whilst providing a dedicated aerodynamic “super design." The new carbon fiber Super Record 12x2 Speed crankset has been made lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra-Torque bracket system with a titanium axle to transfer all of the force the athlete applies to the pedal to the drivetrain. The new Super Record 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters, without affecting the Q factor, which remains constant at 145.5 millimeters thanks to the new hand crank design. The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) combined with the eight fixing screws, optimize weight and stiffness through the increased use of carbon fiber. The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chainrings optimize performance when downshifting in dead spots.
