TA Specialite Vento chainring, 135mm bolt circle for Campagnolo 3- and 2-speed cranksets, designed for outer ring mounting, 50 teeth, silver
The TA Specialite Vento chainrings are designed for Campagnolo 10-speed and 9-speed cranksets with a 135 mm bolt circle. The outer chainring is the same for both 2-speed and 3-speed cranksets.
The 135 mm bolt circle is the Campagnolo road bike bolt circle for 10- and 9-speed cranksets with 3- 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. This allows chainrings such as the Zelito to be fitted.
