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 & Q factors in the category, & cranks made entirely of unidirectional carbon fibre. But the real surprise comes with the first shift: precise, extremely fast, & with no hesitation, thanks to the design of the upshifting & downshifting zones of the XPSS chainrings. Shifting is no longer a problem, not even under extreme conditions.
