Campagnolo gear cables that are compatible with all Campagnolo groupsets, past and present. The "Maximum Smoothness" cables have more strands than standard Campagnolo cablesets and the housing is a lot more flexible making them the essential option if you're running the higher end Campagnolo groupsets or their new 12x range. These added improvements also make them the ideal cablesets if you're running internal cable routing on your bike with tight bends that can cause shifting problems. Compatible with 9x/10x/11x/12x groupsets
