Got a new Park Tool work stand, the 180 dollar model pc4? The one lower from the top of the line model 5. Anyways, the thing is sort of cheap, nothing like a shop stand, which it states has the same type durability? Pop my bike in and the clamp is not level, as if my 18 pound litespeed is pulling the stand forward, so now I need the unit to keep the front wheel for turning right on me? It much better than nothing, but for 180 bucks, I expected it to at least - not lean when my bike is in the clamp!
