5. Setup and Installation
Follow these steps to properly install your MEROCA Quick Release Rods:
- Identify Correct Skewer: Select the appropriate skewer for your wheel (front or rear) and bike type (folding or mountain/road). The longer skewer is typically for the rear wheel, and the shorter for the front. Ensure the correct opening gear (74x130mm for folding, 100x135mm for mountain/road) matches your bike's hub spacing.
- Disassemble: Unscrew the nut from one end of the quick release skewer and remove one of the conical springs.
- Insert Skewer: Insert the skewer through the hollow axle of your bicycle wheel hub. Ensure the remaining conical spring is positioned correctly on the skewer, with the narrow end facing the hub.
- Position Springs: Place the removed conical spring onto the other end of the skewer, again with the narrow end facing the hub.
- Attach Nut: Thread the nut back onto the skewer.
- Install Wheel: Place the wheel into the bike's dropouts (fork for front wheel, frame for rear wheel). Ensure the wheel is centered.
- Adjust Tension: With the quick release lever in the open position, tighten the nut until it makes firm contact with the dropout. The lever should be able to close with significant resistance, leaving an imprint on your palm, but not so tight that it cannot be closed.
- Close Lever: Push the quick release lever fully into the closed position. The lever should be parallel to the fork blade or chainstay/seatstay for safety and aerodynamics.
- Verify Security: Attempt to pull the wheel out of the dropouts. It should be impossible to remove the wheel with the quick release lever closed.
Important: Never ride with a loose or improperly secured quick release. Always double-check the tension and closure before each ride.
6. Operating Instructions
The quick release mechanism allows for rapid wheel removal and installation without tools.
- To Open: Pull the quick release lever away from the wheel until it is fully open. This releases the clamping force. You can then unscrew the nut a few turns if needed to clear the dropouts.
- To Close: With the wheel properly seated in the dropouts, push the quick release lever towards the wheel until it is fully closed. Ensure the lever is parallel to the bike's frame or fork.
7. Maintenance
- Cleaning: Wipe down the quick release rods with a clean cloth periodically to remove dirt and grime.
- Lubrication: Apply a small amount of light grease or oil to the threads of the skewer and the pivot point of the lever once or twice a year, or as needed, to ensure smooth operation and prevent corrosion.
- Inspection: Regularly check for any bends in the skewer shaft, cracks in the aluminum parts, or damage to the springs. Replace immediately if any damage is found.
- Storage: If storing your bike for an extended period, ensure the quick releases are clean and lightly lubricated.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lever difficult to close | Nut is too tight. | Open the lever, unscrew the nut slightly, then try closing the lever again. Adjust until firm but manageable. |
| Wheel feels loose after closing lever | Nut is too loose; insufficient clamping force. | Open the lever, tighten the nut a few turns, then close the lever firmly. Ensure the wheel is fully seated in the dropouts. |
| Squeaking or grinding noise | Lack of lubrication; dirt/debris. | Clean the skewer and apply a light lubricant to the threads and lever pivot. |
| Wheel not centered | Wheel not properly seated in dropouts before closing. | Open the lever, ensure the wheel is pushed firmly and evenly into the dropouts, then re-close the lever. |
