Using this Topeak rack is easy. First, make sure your bike has frame rack bosses as it attaches to them. Adjust the rack legs horizontally and vertically to fit your 24” or 26” wheel Fat Bike. Then, you can attach your Topeak MTX TrunkBag, rear basket, or other compatible rack packs and panniers to the rack using the MTX QuickTrack® plate. When loading your cargo, distribute the weight evenly to avoid overloading one side. Keep in mind that this rack is not compatible with fat bike frames that have an asymmetric rearstay design. For maintenance, clean the rack regularly with a mild soap and water to remove dirt and grime. Check the mounting bolts periodically to ensure they are tight. Avoid using abrasive cleaners as they may damage the aluminum material. Also, don't exceed the maximum weight capacity of 26 kg (57 lb) to ensure the rack's longevity and your safety while riding.
