In their lineup Campagnolo offers the most technology for the dollars in the Chorus components. This commitment to near Record performance holds true for the Chorus Ultra-Torque crank, with two subtle changes.
The Campagnolo Chorus Ultra-Torque 11 Speed Crank Set uses X.P.S.S. – Extreme Performance Shift System – and it’s their best shifting system to date. This design changes the chain upshift and downshift areas. There are 8 upshift sectors and 2 large downshifting sectors and an upgrade tooth profile. The chainring pin has also been optimized for a faster and more precise shifting experience.
As the name suggests, the Chorus Ultra-Torque Crank Set uses Ultra-Torque technology. This technology uses a Hirth Joint Coupling System with self-centering and self-aligning teeth to connect the two semi-axles perfectly so they act as one, stiff axle. This reduces the size of the axle. A single oversized bolt keeps the two pieces together. The bearings are placed outside the bottom bracket shell, ensuring the axle has great rigidity.
While chainring-wise, the Record 11 and Chorus 11 spec the same, Campagnolo changed to a different carbon fiber construction and different bearing technology on the Chorus 11. The Chorus 11 loses the ultra-hollow crank arm design of the Record 11 in favor of unidirectional solid carbon fiber. Along with the crank arm change, the Chorus 11 crank runs on steel bearings instead of the USB ceramic found on the Record. The changes result in a 40 gram weight increase for the Chorus 11 crankset with a disproportionate change in the price.
The end result to these changes is a crankset that shifts just as well as Record with a small weight penalty. Keep in mind, as with all Ultra-Torque cranks, this crankset requires the Ultra-Torque Bottom Bracket cups.
The crank weighs 667 grams and comes in standard (53/39) or compact (50/34). The length options are 170, 172.5 or 175mm. Bottom bracket not included.
