Usage & Installation Instructions
-
Setup & Adjustment
-
Slide the threaded end of the skewer through the rear wheel axle. Adjust the nut on the opposite side until it’s snug against the dropout.
-
With the wheel properly seated in the frame, close the cam lever—it should resist slightly and leave a clear imprint on your palm before locking. Ideal tightness allows smooth engagement without requiring excessive force.

-
Routine Checks
-
Before each ride, verify the lever is closed fully and the assembly is snug—this ensures a safe, wobble-free ride on Malaysian roads, including bumpy city streets and wet surfaces.
-
-
Maintenance
-
After rainy or muddy rides, wipe the skewer clean and apply a light coat of bike grease to prevent corrosion—especially important in humid climates.
-
Precautions
-
Proper Lever Tension
-
Ensure the lever isn’t over-tightened; it should require firm hand pressure but still close smoothly. Over-torquing may damage the dropout or make future removal difficult.
-
-
Secure Fastening
-
Always ensure the cam lever sits parallel to the frame or stay, not sticking out—this helps avoid accidental knocks or catching on clothing or bags.
-
-
Periodic Inspection
-
Regularly inspect the skewer and lever for signs of bending, damage, or rust. Replace promptly if any defect appears to maintain ride safety.
