Gold-coloured, reinforced 101 Octane clip quick-link chain link suitable for 420 101 Octane chains. A quick-link offers the advantage of being able to remove the chain without having to split a link. This can be useful for repairs to other components or for cleaning the transmission. SAFETY NOTE: in order to avoid unintentional opening of the chain during operation, the securing clip must be mounted with the opening OPPOSING the direction of chain rotation! (See detail).
