This set is for Lambretta models and includes the following parts:

More durable inner cables

The trunnions for the gear change and clutch cables are machined from brass and are provided with small plates.

The brass has a lubricating effect in the gear box and clutch mountings. Thanks to the reduced friction of the trunnion in the mounting, the cables are less subject to stress and the risk of tearing will be strongly minimized.

In the trunnions there are small plates which protect the cables from the notch effect and, as a result, this prevents the splitting of the single filaments when tightening the screw. The inner cable distorts less and thus it can be often untied and be easily tied again. For this procedure we suggest you to use pliers for .

The set also includes the suitable Allen key SW 3,5.
