3. Setup and Installation
Follow these steps to properly install your TwoFish Quick Cage Adapter and attach a bottle cage:
- Prepare the Adapter: The adapter comes with pre-installed screws. Ensure these are in place.
- Position the Adapter: Place the adapter on the desired location of your bike frame. The contoured rubber side should face the frame to provide grip and protect the paint.
- Secure with Straps: Wrap the hook-and-loop fastener straps around the bike frame and through the adapter's slots. Pull the straps very tight to ensure a secure fit. For enhanced grip, especially on non-round tubes or when carrying heavier items, consider placing a piece of old inner tube between the adapter's rubber backing and the bike frame.
- Attach Bottle Cage: Align your bottle cage with the screw holes on the adapter. Use the provided screws to firmly attach the bottle cage to the adapter.
- Final Check: Verify that both the adapter and the bottle cage are securely fastened and do not move or slip before riding.

4. Operating Instructions
Once installed, the TwoFish Quick Cage Adapter provides a stable platform for your bottle cage, allowing you to carry water bottles or other accessories. Ensure the bottle cage is securely fastened to the adapter and the adapter is tightly strapped to the bike frame before each ride. Periodically check the tightness of the straps and screws, especially after riding on rough terrain, to prevent movement or loss of items.
5. Maintenance
- Cleaning: Clean the adapter with a damp cloth as needed. Avoid using harsh chemicals or abrasive cleaners that could damage the material.
- Strap Inspection: Regularly inspect the hook-and-loop fastener straps for any signs of wear, fraying, or damage. Replace the straps if they show significant deterioration to maintain secure attachment.
- Screw Tightness: Periodically check and tighten the screws that attach the bottle cage to the adapter. Loose screws can lead to instability.
6. Troubleshooting
Issue: Adapter swivels or slips on the bike frame.
Solution:
- Ensure the hook-and-loop fastener straps are pulled as tight as possible around the bike frame.
- For additional grip, especially on frames with irregular shapes or when carrying heavy bottles, consider placing a small piece of rubber (e.g., from an old inner tube) between the adapter's rubber backing and the bike frame. This can significantly increase friction and prevent movement.
