5. Installation Guide

Follow these steps to properly install your Topeak Uni Super Tourist Fat Bicycle Rear Rack:

1. Prepare Your Bicycle: Ensure your bicycle is stable, preferably on a stand. Clear any existing accessories from the rear dropout eyelets and seat stay mounts.
2. Attach Lower Mounts: Secure the lower ends of the rack to the rear dropout eyelets on your bicycle frame using the provided bolts. For disc brake bikes, ensure proper clearance around the caliper. Do not fully tighten yet.
3. Install Upper Mounting Brackets: Attach the adjustable upper mounting brackets to the seat stay mounts on your bicycle frame. These brackets allow for angle adjustment to ensure the rack platform is level. Use the provided bolts and washers.
4. Adjust and Align: Adjust the length and angle of the adjustable legs and upper brackets to ensure the rack platform is level and centered over the rear wheel. Ensure sufficient clearance between the rack, tire, and any fenders.
5. Tighten All Fasteners: Once the rack is correctly positioned, progressively tighten all bolts and nuts. Start with the lower mounts, then the upper brackets, ensuring even tension. Do not overtighten.
6. Install Reflector/Lights: Attach the included RedLite Mount and/or Tail Light Mount to the designated points on the rear of the rack.

Note: Some fat bike frames may require minor adjustments to the mounting brackets for optimal fit.

7. Maintenance

• Cleaning: Clean the rack regularly with a damp cloth and mild soap. Avoid abrasive cleaners that could damage the finish.
• Inspection: Periodically inspect the rack for any signs of wear, damage, or corrosion. Check all welds and connection points.
• Fasteners: Ensure all bolts, nuts, and quick-release mechanisms remain tight. Re-tighten as necessary.
• Lubrication: No specific lubrication is required for the rack itself, but ensure any moving parts of attached accessories are maintained according to their respective manuals.

8. Troubleshooting

• Rack is Loose: Check all mounting bolts and ensure they are tightened to the recommended torque. Verify that the adjustable legs are securely fastened.
• Bag Not Locking: Ensure the MTX QuickTrack™ base on the bag is clean and free of debris. Verify that the rack's channel is clear and the release button mechanism is functioning correctly.
• Insufficient Tire Clearance: Re-adjust the rack's height using the adjustable legs. Ensure the rack is mounted correctly for your fat bike's wheel size.
