Safety Information
WARNING: Bikes and racks falling into the road can cause serious accidents. Always ensure bicycles are securely attached to whatever rack they are being used with.
Always check that the stem and seat post are securely attached to the bicycle before installing the adaptor bar.
Do not use the 900B if any parts are broken.
The distance between the stem and seat post should not be less than 18 inches or greater than 27 inches.
Maximum load capacity: 35 LB. Do not exceed this weight limit.
Setup and Installation
Step 1: Attach to Handlebar Stem
Ensure the bicycle's seat post and stem are securely attached. Attach the large "U" hook of the adaptor bar to the bicycle's stem. Insert the bolt from the Quick Release Pin through the holes on the large hook, and ensure the retainer clip on the Quick Release Pin is properly closed.

Step 2: Extend and Attach to Seat Post
Extend the unit by pulling the smaller hook end. Attach the small hook to the bicycle's seat post. The internal spring will maintain constant tension to hold the bar securely.

Operating Instructions
Mounting Bicycle on Rack
With the adaptor bar securely installed, lift your bicycle and place the adaptor bar onto the arms of your vehicle's bike rack. Ensure the bicycle is balanced and that the rack's cradles and straps are used to further secure the bicycle.

Always use additional tie-down straps or bungee cords to prevent wheels from spinning and to secure the bicycle to the rack, preventing movement during transit.
Maintenance
- Regularly inspect the adaptor bar for any signs of wear, damage, or corrosion.
- Check the quick release pin and retainer clip for proper function before each use.
- Keep the plastic-coated hooks clean and free of debris to prevent scratching your bicycle's finish.
- Store the adaptor bar in a dry place when not in use to prolong its lifespan.
Troubleshooting
Problem: Adaptor bar does not fit the bicycle frame.
Solution: Ensure the distance between your bicycle's handlebar stem and seat post is within the 18" to 27" range. The internal spring allows for adjustment within this range.
Problem: Bicycle feels unstable on the rack.
Solution: Double-check that both the large U-hook and the small hook are securely attached and the quick release pin is fully engaged. Ensure the internal spring is providing adequate tension. Use additional tie-down straps to secure the bicycle to the rack.
Problem: Adaptor bar is scratching the bicycle frame.
Solution: Verify that the plastic coating on the hooks is intact. If damaged, consider replacing the adaptor bar or adding protective padding to the contact points on your bicycle.
