Campagnolo Chorus 11 Speed Chainset 2012-2014

This year's model is carbon with aluminium chainrings. These have an anodised surface for what Campag calls its ‘ESP’ (Enhanced Shifting Performance) Actuation System. This is claimed to help move the chain to the large chainring more effectively when shifting under pressure.

Shifting is certainly smooth and impressive, and quieter than Centaur's, and we reckon the surface treatment is the reason for this. We also found it satisfactorily stiff when cranking up the gears.

The steel axle is moulded to each crank arm and separated in the middle using a toothed link a neat and effective solution. It results in a Q-factor (the distance between the outside face of both cranks) 5mm narrower than most, with a weight just 40g heavier than Shimano Dura-Ace’s benchmark-setting 7900 crankset.
