Double ring of bolts. Assembly of the large chainring on the crank is guaranteed by a ring of 123 mm bolts, while the two chainrings are coupled together by a ring of 96 mm bolts.

Potenza’s 4 arm spider design makes for one single crankarm for all chainring options 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 groupset is as easy as changing 8 bolts and two chainrings. While the 4-arm bolt pattern offers advantages in terms of practicality, the Campy Tech Lab designed it primarily with performance characteristics in mind. The 8 bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity to the point of surpassing its direct competitors in laboratory tests.
