When your bike is up on stands grab the tail and rock it back and forth.... This will determine how good the stands are in my opinion... Pit Bulls will rock up on 1 wheel with the bike still on... Others will flex and fold...At least the Handys ect with no bracing... I do not get paid from PitBull but all I am saying is after years of being at the track and working on bikes I have never seen a Pitbull fail front or rear and I cant say that for Handy's Powerstands ect... If your in this sport for time get something you wont have to buy over again....
Personally, I wouldn't spend a dime of my money on anything other than a PitBull stand. Why buy anything but the best? A small investment in a quality product will pay off tenfold. Heck, my PitBull stands will probably outlast me they're made so well.
