## Long description

The ER4 WMC-2525 repair kit for bicycle inner tubes is a 25-piece set designed to restore punctured tubes and perform minor wheel maintenance. The compact kit groups adhesive patches, mounting tools, valve tools and a wrench in a single package for carrying on rides or keeping in a workshop. Components are intended to enable quick on-the-spot repairs and routine tube servicing without requiring large standalone equipment.
Advantages
The kit combines patching materials and simple hand tools to address common punctures and small mechanical adjustments. Adhesive patches and preparation tools provide a straightforward repair flow from damage cleaning to sealing. Inclusion of valve tools and a small wrench reduces the need for additional items when removing or reinstalling wheels and valve cores. The set’s compact organization supports portability and easy storage.
Suitable for
 Road and commuter cyclists carrying a compact repair set for rides
 Mountain bikers needing a lightweight puncture repair solution on trails
 Home use for routine tube maintenance and occasional repairs
 Bike workshops and mobile technicians for quick temporary fixes
Key specifications
 Contents: 25 pieces including adhesive patches, valve tools, mounting/removal tools and a small wrench
 Patch type: adhesive patch system for inner tube repair
 Tools: valve core tool, tire lever(s) / mounting tool(s) and a compact wrench for wheel components
 Intended use: punctured inner tube repair and minor wheel component adjustments
 Packaging: portable kit designed for carrying on rides or storing in a workshop
How to use
Locate the puncture by inflating the tube and listening or using water to find air bubbles, then dry and mark the damaged area. Use the included preparation tool to roughen and clean the tube surface around the puncture, apply adhesive patch according to the patch instructions and press firmly until set. If valve servicing is needed, use the valve tool to remove or tighten the valve core. Use the mounting tools and wrench to remove and reinstall the wheel or to pry the tire bead off and back on when accessing the tube. Follow standard safety precautions: work on a stable surface, avoid sharp contact with tools and verify that the repair holds by partially reinflating and inspecting before full inflation and riding.
Usage recommendations
Store the kit in a dry place and keep adhesive patches sealed until use. For longer-lasting repairs, ensure the tube surface is clean and dry before applying patches and allow the adhesive to cure. Replace patches or tools that show wear; use appropriate tire pressure after repair and inspect the tire casing for embedded objects before reuse.
