Campagnolo Record Ultra Torque Carbon Road Crankset 172.5

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.

NB, these cranks have the 5-bolt, 135mm BCD, smallest inner ring is 39-tooth.
