Special design of chain up and downshift zones – chainring pin profile optimization – allows for faster and more precise shifting in all conditions.
The new design of the chains up shifting and downshifting has been analysed to the smallest detail with mathematical functions to simulate possible movements of the chain on the chainrings and design optimal angles. Furthermore, repeated lab tests on the speed and precision of the shifting action have allowed us to complete the product's optimization.
We have also reviewed the profile of the chainring teeth to enhance efficiency and compatibility with the 11-Speed chain and the cleverly-shaped derailleur to contribute to making the movement of the chain extremely quick, even under load.
8 CHAIN UP SHIFT ZONES, AND 2 CHAIN DOWNSHIFT ZONES:
Faster and more precise shifting, even under stress.
Increase in performance while also saving weight.
Following the Campagnolo® philosophy of keeping the bearings at the widest stance possible with a large diameter axle the Over-Torque™ construction has an extremely wide stance for bearings in addition to a 30mm axle diameter.
HOLLOW CRANKS WITH ULTRA-HOLLOW™ TECHNOLOGY:
Reduced weight of stress – free sections, improved crank set weight to stiffness ratio.
