Campagnolo`s Potenza HO 11 fills the gap between Veloce and the higher tier components of the Chorus, Record and Super Record series. The Potenza parts profit from the "trickle down" effect of top-end technology and solutions originally designed for the benefit of the World Tour level athletes and which brings several technologies found on Super Record to more accessible groupsets in the Campagnolo range. Despite Potenza 11 is the newest groupset in the Revolution 11+ family Campagnolo goes one step further and makes it a part of the Camplagnolo Disc Brake Project. The shared DNA is so evident that many components of the groupset will require a close look beyond the logo to identify any significant difference which often is represented by a mere change in material. But Campagnolo doesn`t produce different grades of performance and with this in mind every product leaves the factory only when it has proven to live up to their own quality standard. So the Potenza components are technically the higher tier groups` equal in every way. The design of the 4 arm carbon fiber cranksets that so well identify the Super Record, Record and Chorus groupsets has also found its way into the Campagnolo Potenza 11 Power-Torque crank. But at the Potenza it is hollow forged aluminum and not carbon which keeps the weight to a minimum while maintaining the performance of the 4 arm construction. The Potenza`s 4 arm spider design makes the use of one single crankarm for all chainring options possible thanks to its unified bolt pattern which allows for all 3 chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankset. Changing between compact and standard with the Potenza 11 groupset is as easy as changing 8 bolts and two chainrings. The 8 bolt pattern helps not only to hold the chainring in place but also supports it while increasing the system rigidity at the same time. The HO version of the Potenza 11 crank has been especially optimized for disc brake frames with 142 mm dropouts. A modified chainline provides excellent precision for 142mm rear spacing and does so without altering the Q factor. The Potenza 11 crankset adopts the Power Torque System, which makes it possible to obtain very high values of torsional stiffness and efficient power transmission, without increasing the lateral bulk. Thanks to the oversize axle and external cups, the system is very rigid, but unlike other systems that are broadened in the ankle area because of the external cups, the Potenza 11 crankset does not make it necessary to change the pedaling position. More rigid and lighter, it transfers the force exerted by the athlete without wastage and with maximum ergonomics.
