Using the Topeak Omni Quicktrack MTX Adapter is easy. First, make sure your rear rack fits the width requirements (90mm - 120mm) and tube diameter (10mm - 12mm). Then, attach the adapter to the rear rack deck. After that, you can mount your Topeak TrunkBags or rear baskets on the adapter. When it comes to the load, always keep in mind that the maximum load is limited by the rack's rating, so don't overload it. For maintenance, clean the adapter regularly with a mild soap and water. Avoid using harsh chemicals as they may damage the engineering - grade polymer material. Also, store it in a dry place when not in use to prevent any corrosion or damage.
