Campagnolo Centaur Triple Crankset.
Use as is for a 10 speed system or retrograde to 8/9 speed by simply adding a
Le Tour 0.4 mm chainring spacer to every chainwheel bolt behind the outer 10 speed ring and to every chainwheel stud behind the smallest ring. That will space both rings .4mm away from the middle ring and ensure precise shifting with your 8/9 speed drivetrain.
