its not a design flaw i can tell you that much. its the nature of the system. 2 wheels on seperate bending system....its gonna have its own issues. split limbs may help the situation but i don't see them doing that. its a very good system regardless. barnsdale limbs are the best period.
But why do some do it an others not??Or is it more of a issue that maybe all but alot of them to a lesser degree?
