Campagnolo Super Record 12V Carbon Ultra-Torque 39X53 Crankset

Campagnolo Super Record 12V Carbon Ultra-Torque 39X53 Crankset

New Super Record 12x2 Speed crankset: a super-concentrated innovation to obtain maximum values of stiffness and derailleur precision and all this in a dedicated and aerodynamic 'super design' .

The new Super Record 12x2 Speed cranksets, made of carbon fiber lightened inside thanks to Campagnolo's 'Hollow Technology', use the Ultra-Torque locking system with a titanium shaft to transfer all the printed power to the transmission. by the athlete on the pedals.The new Super Record 12x2 Speed cranksets can be mounted on all types of frames , whether disc brakes or not, since they optimize the chain travel on frames with a rear stop of 130, 135 or 142 millimeters without affecting the Q factor, which, thanks to the new design of the connecting rod, remains at 145.5 millimeters.

The use of CULT ceramic bearings allows you to obtain the already famous smoothness that has become a Campagnolo trademark. The innovative design of the external chainring, thanks also to the profiled bolt, guarantees faster and quieter uphill shifting. The symmetrical design of the inner chainring teeth also improves stability at chain crossings. The standard double diameter of the bolt circle (112 and 145 mm) in combination with the 8 fixing screws, allows for optimization of weight and rigidity, thanks to the greater use of carbon fiber.

The different number of bolts of each of the three chainring combinations (34/50, 36/52, 39/53) favors uphill deflection thanks to an optimized coupling for each combination. In addition, the special reliefs inside the outer plates favor deflection in the dead points of pedaling, optimizing performance.

Characteristics:

• Weight: 618gr.(172.5mm)
• New space-saving design:
  • Increases compatibility with all frame systems regardless of rear triangle width.
• Right crank rings connected in pairs in areas subject to the maximum force applied by the rider.
  • Provide maximum crankset rigidity during uphill drifting
• Q factor unchanged (145.5).
  • The spaces and biodynamics of pedaling do not change.
• Unidirectional carbon fiber cranks, titanium axles and aluminum chainrings:
  • Great rigidity and optimal power transfer
• Symmetrical teeth for the inner chainring:
  • Smooth and precise transmission even in the most important junctions.
• Optimized design for each dish combination:
  • Maximum performance.
• Double Bolts Circle Diameter:
  • Improves system rigidity and reduces weight for greater use of carbon fiber.
• Surface treatment of dishes for longer life .
