The completely redesigned Campagnolo Super Record crankset represents increased rigidity as well as fresh and cutting-edge aesthetics. This version uses a 4-arm spider design which makes for one single crankarm for all chainring options thanks to its unified bolt pattern.
The new bolt pattern 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 is now as easy as changing 8 bolts and two chainrings. The new design incorporates a 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.
In addition to completely redesigning the spider, Campagnolo engineers dedicated a great deal of energy towards a completely new crankarm that is a great deal stiffer than previous versions. Add this new highly rigid crankarm to the new four-arm spider design and you have a complete crankset that not only excels at transferring power more than any previous version but one that is also more versatile with respect to gearing.
