Campagnolo, based on the experience of the Ekar 13s group, has created a new series of boxes for the Super Record 13 group, designed to guarantee more fluid, fast, precise and silent gear changes.

LOptimization of space e LUsing the 13 -speed chain allow you to insert an additional ratio without changing the standard of the body free wheel N3W, avoiding adapters or dedicated hubs.

The renewed teeth proper and the Black Chrome finish improve silence, resistance to wear and durability.

The most linear progression of relationships ensures an ideal cadence on each ground, reducing the athlete’s effort and optimizing performance.

Available in four configurations, the box combines monoblocchi and independent pignons for a perfect balance between choice, precision and durability.
