Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Topeak Explorer MTX Rear Bike Rack. Designed for durability and versatility, this rack is compatible with 26-inch, 27.5-inch, and 700c wheel sizes. It features a robust 6061 T6 aluminum construction with stainless steel hardware, ensuring reliable performance for your cycling needs.
The Explorer MTX rack is QuickTrack compatible, allowing seamless integration with Topeak MTX TrunkBags and rear baskets. It supports both updated MTX 2.0 accessories and is backwards compatible with original (1.0) MTX accessories.
Setup and Installation
Proper installation is crucial for the safety and performance of your rear bike rack. The Topeak Explorer MTX rack is designed for eyelet mounting and includes 4-point adjustable extenders to accommodate various bicycle frames.
Installation Steps:
- Attach Lower Mounts: Secure the lower rack stays to the eyelets near the rear axle of your bicycle frame using the provided hardware. Ensure a snug fit without overtightening initially.
- Position Rack Deck: Place the main rack deck over the rear wheel, aligning the upper mounting points with your frame's seat stay eyelets or brake bridge.
- Install Upper Extenders: Connect the 4-point adjustable extenders from the rack deck to the upper mounting points on your frame. Adjust the length of the extenders to ensure the rack deck is level and centered over the rear wheel.
- Tighten All Fasteners: Once the rack is properly aligned and level, systematically tighten all bolts and screws. Start with the lower mounts, then the upper extenders, ensuring all connections are secure. Do not overtighten, as this can damage your frame or the rack.
- Final Check: Gently shake the rack to confirm it is stable and does not wobble. Verify that there is adequate clearance between the rack, the wheel, and any moving parts of your bicycle.
Operation and Usage
The Topeak Explorer MTX Rear Bike Rack is designed for carrying cargo efficiently and securely. It has a maximum load capacity of 55 pounds (25 kg).
Using with QuickTrack System:
- MTX TrunkBags: Slide your QuickTrack compatible MTX TrunkBag onto the rack until it clicks into place. To remove, press the yellow release button (if applicable) and slide the bag off.
- Rear Baskets: Attach QuickTrack compatible rear baskets by sliding them onto the rack until they lock.
The rack includes a rear cargo spring, which can be used to secure smaller items or help stabilize a milk crate or similar container for transport.
Care and Maintenance
Regular maintenance will extend the life of your Topeak Explorer MTX Rear Bike Rack.
- Cleaning: Clean the rack with mild soap and water. Rinse thoroughly and dry completely to prevent water spots or corrosion. Avoid abrasive cleaners.
- Inspection: Periodically inspect all mounting bolts and hardware for tightness. Vibrations from riding can cause fasteners to loosen over time.
- Corrosion Prevention: The rack is constructed from 6061 T6 aluminum and stainless steel hardware, which are resistant to corrosion. However, wiping down the rack after exposure to wet or salty conditions is recommended.
- Damage Check: Check for any signs of damage, such as cracks, bends, or excessive wear. Replace any damaged components immediately.
Troubleshooting Common Issues
If you encounter issues with your Topeak Explorer MTX Rear Bike Rack, consider the following:
- Rack Wobbles: Ensure all mounting bolts are securely tightened. Check for any loose connections at the lower eyelets and upper extenders.
- Insufficient Clearance: If the rack interferes with the wheel or other bike components, re-check the adjustment of the 4-point extenders. Ensure the rack is level and positioned correctly.
- Difficulty Attaching MTX Bag: Verify that your bag is QuickTrack compatible. Ensure the rack's QuickTrack rails are clean and free of obstructions. Apply a small amount of silicone lubricant if sliding is stiff.
- Unusual Noises: Inspect all contact points between the rack and the bike frame. Loose bolts or friction between components can cause noise. Tighten or apply protective tape as needed.
If problems persist, consult a professional bicycle mechanic.
