Adjusting Screw RMS brake cable, left or right

Adjuster screws for vintage scooter control cables, in all common types and sizes.

The clutch, gears and brakes found on most vintage geared Vespa and Lambretta scooters are operated by control cables leading from the steering assembly. Due to the definitional frame design with engines mounted at the rear, this inevitably makes these items quite long. To ensure complete control they should be in perfect working order!

• All common varieties available.
• Identical replica replacements.
• Optimal function guaranteed.

Clutch plates, brake pads and brake shoes wear during operation, the length of control cables can vary once they have settled following initial use. These factors affect the mechanical play at the handlebar levers and foot pedal, which control the essential function of the clutch and brakes. To counter this adjuster screws are located at the component-end of these cables, allowing convenient adjustment of their operative length.

Over time these adjustment screws also wear, break, corrode or are deformed by contamination or mechanical brutality. Whatever the damage, they all require immediate replacement. To facilitate this we now have all common types and sizes (plus a few more besides!) available, making it again possible to perfectly replace and set up the control cables found on all vintage scooters. This not only increases safety, but also restores full control over the operation and functions of the scooter.

Important: Always check and ensure the inclusion of the correct lock-nut for each adjuster screw as not all suppliers include these essential items!

The SIP adjuster screws

All Vespa models are factory-equipped with a variety of different adjuster screws, which can have different threads, lengths, diameters and spanner-sizes, etc. Many were only available including small deviances and compromises from the OE specifications, such as the original 30mm clutch cable adjuster screw being replaced by a 20mm version. To solve this problem we are having adjuster screws produced where none are available, or to replace those of inferior quality. The SIP adjuster screws are produced in high quality and are exact replicas of the original dimensions and grades.

Conclusion: A small but easily ignored component, absolutely essential for safe and accurate operation of all vintage scooters!

The best set up – our SIP-TIP:

• Our SIP Performance control cable kits complement these brand-new adjuster screws ideally!
• The cables in turn, can be operated more cleanly and quickly with a pair of the SIP gear and throttle pulleys.
• Worn levers also cause undesired mechanical play in the operation of the control cables. We recommend that these also are checked and if necessary replaced during this upgrade maintenance.
