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

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.

SRAM's Force 22 Crankset uses unidirectional carbon arms with a forged aluminum spider and integrated bottom-bracket axle to ensure top-notch stiffness for awesome power transfer and exceptionally low weights.
