TA Specialite Vento chainring

The TA Specialite Vento chainrings for 2-speed Campagnolo 10- and 9-speed cranksets with a 135 mm bolt circle. The inner chainring is without shift aids on 2-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 gear ratios.

On 3-speed cranksets, the middle chainring requires additional shift aids to allow the chain to be shifted from the small chainring.
