The set is suitable for tubed and many tubeless wheel systems that use removable valve inserts. Included parts restore airtight seating and enable dependable inflation and pressure retention after valve wear, damage, or when servicing high-pressure bicycle tires.

Advantages

The set includes two valve inserts and complementary components designed for straightforward replacement without removing the rim tape in most installations. Components are manufactured to ensure a tight fit with standard Sclaverand valve stems and provide corrosion resistance appropriate for cycling use. The compact assortment covers common repair needs, reducing downtime and allowing repair work both in workshops and on the road.

How to use

Select the appropriate valve insert and components for the affected valve stem. Remove the valve cap and unscrew the valve core if applicable, then extract the old insert or core assembly. Insert the replacement valve insert into the valve stem, press or screw it into place according to the valve construction, and verify a secure fit. Reassemble the valve core and cap, inflate the tyre to the recommended pressure, and check for leaks at the valve seat using soapy water or a leak-detection method.

Recommendations

When installing valve inserts, ensure threads and sealing surfaces are clean and free of debris. Apply moderate torque to threaded parts to avoid damage; use proper tools when necessary. After installation, confirm pressure retention before riding and recheck after the first few kilometres. Keep spare inserts as part of a basic repair kit for reliable roadside maintenance.
