2012 Campagnolo Chorus collection follows the path of its big brother, Record, and receives an extreme makeover. The skeleton brakes feature forged arms that are stronger and gives the brakes a maximum life cycle. Skeletonized arms saves weight with the same life and stiffness as before. Differential brakes mean the front brake (Dual Pivot) is now more powerful while the rear brake is light and modulable (Single Pivot). The orbital pad adjustment gives the brakes optimum interface with the rim while giving maximum braking performance. A special pad compound creates excellent balance between performance on dry and wet surfaces.  Campagnolo redesigned its pad holders so it's easier to change your brake pads.
