Kickstand took 3 times longer to install than the disc brake compatible model made by a different manufacturer but sold by the same vendor. Screws were small and stripped more easily than the higher quality ones with the other model, which was a little less than twice as expensive. After securing the kickstand in place on my son's 20" mountain bike, I sat on the bike and leaned on the kickstand to make sure it was secure. I weigh less than 195 lb and have done this on our other 7 bikes with various models of kickstands with no problem. In this case however the piece of pot metal that comprised the primary portion of the kickstand snapped in two. 30 minutes + $12 down the drain!
