Ultra Torque Crankset
Campagnolo starts with revamping the crankset. The Chorus crankset has been totally redesigned on the basis of Campagnolo's Ultra-Torque technology. The cranks are made of unidirectional carbon combined with multidirectional carbon to achieve a structure with extremely high strength and rigidity values. There is no aluminium core inside but an uncompressible low-density material which resists the enormous molding pressures applied during the production process developed by Campagnolo engineers.

Integrated Bottom Bracket
The bottom bracket semi-axles are attached directly to the carbon structure without using metal inserts. The only metal insert in the crankset is the seat for the pedal thread.
The use of a large integrated axle and external cups has lightened the weight of the assembly and raised the rigidity values, all without increasing the lateral bulk of the bottom bracket. As a result riders can benefit from higher performance without varying the pedal stroke.  The new Ultra-Torque crankset with integrated bottom bracket weighs only 735 grams.

Skeleton Brake Calipers
Skeleton brakes. Chorus brakes are inspired by Campagnolo's Skeleton design. These new brakes feature increased rigidity in the points of highest stress and removal of material where there are no stresses. This solution has produced a considerable weight reduction with boosted performance.
Chorus 2007 brakes are of the differentiated type: a powerful front brake and a progressive rear one. Thanks to the differentiation of the two brakes it is possible to obtain the maximum braking power while reducing the risk of rear wheel locking to the minimum. This means lower stopping spaces and greater safety.

QS Shifting
QS (Quick Shift) Front Derailleurs and Ergopower QS. The Chorus QS 2007 front derailleurs, in both the standard and compact crankset versions, have a longer outer link to provide snappier and lighter shifting in combination with Ergopower QS controls. The aluminium fork with a special anti-wear treatment increases the rigidity of the whole and overall performance.
