The Campagnolo CSD Chain Catcher system reduces the risk of the chain falling inside the frame when correctly set-up. Periodically check to make sure that the distance between the inside chainring and the Chain Security Device (CSD) is always set at 1mm space for correct functioning of the device. Compatible with braze-on front derailleur only
The set-up adjustment of the Campagnolo CSD is completely independent from that of the front derailleur.
