This thing has proven to be the worst thing I could have done to my bikes. Unless you need it to get your bike on and leave it there forever don't waste your money. The damn thing requires a considerably amount of strength be set up on the rear wheel skewers even for a fit biker in the late '30ies like I am. I only wonder if a 60 and plus year old cyclist would have not only the strength but rather the patience to set it up on his/her bike. Then there's the take it down process. Since the stand frame is rather stiff taking it off is a pain in the heck and there's a huge risk damaging spokes or hit rear derailleur bad. And forget about "unclamping" it from both sides at the same time unless of course you name is The Incredible Hulk.
And,least but not last in order to be completely stable it really need a flat floor/surface to lay on. Even the smallest gap between tiles can cause the bike be very unstable . Save yourself some money,tons of better stands out there worth paying some extra cash if necessary.
