TA Specialite Vento chainring

The TA Specialite Vento chainrings for Campagnolo 10-speed and 9-speed cranksets with a 135 mm bolt circle. The middle chainring differs for 2-speed and 3-speed cranksets.

The 135 mm bolt circle is the Campagnolo road bike bolt circle for 10-speed and 9-speed cranksets with 3-speed and 2-speed gearing.

On 3-speed cranksets, the middle chainring requires additional shifting aids so that the chain can be shifted from the small chainring.

The small chainring on 3-speed cranksets has a 74 mm bolt circle. Chainrings such as the Zelito can be fitted there.
