To use this rack, first mount it securely on your 29er mountain bike with disc brakes. You can attach an MTX TrunkBag or rear basket easily thanks to its QuickTrack compatibility. When loading items, make sure to distribute the weight evenly to keep your bike stable. Avoid overloading the rack as it may affect your bike's handling. For maintenance, regularly check the mounting bolts to ensure they are tight. Clean the rack with a mild soap and water solution to keep it in good condition.
