- Unpack Components: Carefully remove all parts from the packaging. Verify all components listed in "What's in the Box" are present.

- Attach Rack to Seatpost:
Position the quick-release clamp of the rack around your bicycle's seatpost. Use the rubber spacer provided to protect the seatpost and ensure a snug fit.
Tighten the quick-release mechanism until the rack is secure, but do not overtighten. The rack should be firm without excessive movement.

- Adjust Rack Position:
The rack is universal and can be adjusted for optimal positioning. Loosen the two bolts that secure the main rack platform to the seatpost attachment.
Adjust the rack forward or backward, and ensure the rear reflector (if installed) has adequate clearance. Re-tighten the bolts once the desired position is achieved.

- Install Side Supports (Optional for Panniers):
If you plan to use pannier bags, attach the side support brackets to the rack and the bicycle frame using the provided hardware and rubber spacers.
Secure these supports to the frame's eyelets near the rear axle. Ensure they are tight but not overtightened.

Operating Instructions
Securing Cargo
- Place your cargo on the rack, ensuring weight is distributed evenly.
- Use the included bungee cords or other appropriate straps to firmly secure your items to the rack.
- Verify that no items are dangling or could interfere with moving parts of the bicycle.
Load Capacity
The maximum load capacity for this rack is 22.1 pounds (10 kg). Do not exceed this limit to ensure safety and product longevity.
Maintenance
Regular Checks
- Periodically inspect all mounting hardware for tightness. Vibrations from riding can loosen bolts over time.

- Check for any signs of wear, cracks, or damage to the rack or its components. Replace damaged parts immediately.
Troubleshooting
Common Issues and Solutions
Rack is wobbling or not stable
- Check Seatpost Connection: Ensure the quick-release clamp on the seatpost is tightened sufficiently. Some users have found that adding pipe tape around the seatpost or the rack's internal connection point can reduce play.
- Verify All Bolts: Confirm that all bolts, especially those connecting the main rack to the seatpost clamp and any side supports to the frame, are fully tightened.
- Load Distribution: Unevenly distributed weight can cause instability. Reposition your cargo to balance the load.
- Compatibility: While designed for universal fit, some bike geometries or seatpost materials (e.g., carbon) may not provide optimal stability. Consider alternative mounting solutions if issues persist.
Insufficient Tire Clearance
- Adjust Rack Position: Loosen the bolts securing the main rack platform and adjust its position further back or forward to achieve adequate tire clearance. The rack can be flipped for different configurations.
