Campagnolo Record UT Carbon Crankset 175mm 53/39The new Record™ crankset with integrated bottom bracket is the most technologically advanced version of the Ultra-Torque™ system. The oversize axle system with outer cups is combined with a carbon fibre structure which is completely hollow internally Not only is the main crank arm hollow, but also the small arms supporting the chainrings of the RH crank. Unlike cranks of the previous generation, which had a metal insert for interfacing with the bottom bracket axle, Ultra Torque™ carbon cranks have an oversize steel axle fixed directly to the carbon structure of the crank, giving a considerable weight saving.8032758979897
