@@MikeMu This product was discontinued in 2019. I purchased the bag in 2013 and it was great, but it’s slightly poorly made. The thread for the wheel is actually a nylon lock but that no longer can be threaded in with the hex bolt. Many x200 owners resorted to replacing the wheels(poorly made) to inline skating wheels and while I successfully replaced the left(cracked wheel), my attempt to replace the right wheel caused the thread(nut) to loosen and then come apart. I don’t recommend these bags, though the x200 was incredible for the ten years I had it. Manfrotto, LOWEPRO’s sister company, now makes the roller bags. Lowepro discontinued their roller line, with the only exception being the rugged roller.
