The Campagnolo Record 11 Speed Crankset is compatible with 2015 Campagnolo Super Record, Record, and Chorus Groups.
USB uses the same ceramic ball bearings as Super Record crankset's CULT bearings, but does not include Super Record's Cronitect races. For non-professional cyclists the minute difference in longevity and friction are nearly impossible to identify.
Externally, the big changes are in the crank arms and chainrings.
The crank arms lost a longtime comrade when their number fell to four, which nets a claimed 12% gain in torsional stiffness. They have a little less metal, and a bit more lighter, stiffer carbon that extends all the way to the big ring.
Crank arms are strategically hollowed in areas that don't need the extra reinforcement in order to reduce weight compared to the new Chorus model, which is only hollow on the non-drive side.
Instead of sharing one set of five chain ring coupling holes, both rings now get the benefit of their own set. This effectively standardizes the crankset's bolt circle diameter and lets you switch from compact to standard rings without swapping the entire unit. The full-size rings have eight pins with corresponding up- and downshift zones for immediate shifting engagement, while the semi-compact and compact rings have four pins. All three options are also more aerodynamic, using the same deep rim philosophy that makes you love your Shamal wheelset.
Familiar elements include the Ultra-Torque axle and its self-centering, self-aligning Hirth joint, which is still as efficient at transfer power as heavier, single-piece axles.
Besides distinguishing themselves for their unparalleled quality and performance, Campagnolo products have also become the benchmark of design. This is testified by the prestigious Compasso d'Oro award granted by the Associazione Design Italiano in recognition of Ergopower integrated controls and Shamal high-profile wheels.
CampagnoloIn was named by the Wall Street Journal as one of the most prominent sports brands in the world. A reputation earned not only as a result of the countless successes achieved in racing competitions, but also by virtue of the attention given to quality and to service that sets this company apart from all others.
