Using the Topeak TetraRack M2 is a breeze. First, attach the rack to your MTB's full - suspension seatstays or hardtail frame if it doesn't have rack eyelets. Adjust the innovative top plate to level it regardless of the seatstay angle. To use with Topeak TrunkBags, slide them onto the integrated QuickTrack system and lock them in place. You can release the bags with just a push of a button. When using the hook - and - loop strap mounting system, make sure to cinch it down tightly to keep your load stable. As for maintenance, regularly check the mounting points for any signs of wear or looseness. Clean the rack with a mild detergent and water to keep it in good condition. Avoid using abrasive materials that could damage the finish.
