An extra weapon for achieving victory. The Record® crankset is designed to transmit 100% of the cyclist's power to the wheel: maximum torsional stiffness of the system, the best U and Q factors in the category, and cranks made entirely of unidirectional carbon fibre.
But the real surprise comes with the first shift: precise, extremely fast, and with no hesitation, thanks to the design of the upshifting and downshifting zones of the XPSS™ chainrings. Shifting is no longer a problem, not even under extreme conditions.
Pressure on the pedals is transmitted efficiently without any power loss.
Sophisticated mechanical features on the parts that move the chain up and down guarantee maximum efficiency during shifting. A further evolution of the chainrings used by Pro-Teams in 2014.
DIFFERENTIATED NUMBER OF PINS DEPENDING ON THE CHAINRING COMBINATION
Constantly optimum engagement of the chain. Maximum shifting efficiency.
DOUBLE STANDARDIZED BOLT CIRCLE DIAMETER ON ALL COMBINATIONS
Maximum stiffness and lightness thanks to extension of the carbon fiber crank close to the chainrings with 112 mm for the small bolt circle diameter and 145 mm for the large one.
USB™ ceramic ball bearings reduce friction, guaranteeing the maximum smoothness. Resistant to corrosion and wear, they maintain consistent performance over time.
INTEGRATED CRANK/CHAINRING MOUNTING SYSTEM
reduced weight – easy maintenance.
