UmmYeahOk said:Simple, you just slowly tighten the top screws on each side. The nuts are either welded to the bar, or held in place by a wrench. The force will cause the lower bars upward. Since the top cant go down, this slowly forces the pulley to pull upward too. Its quite ingenious.
My rather long experience with Triumphs indicates that thing isn't sturdy enough to work. I'm sure I could bend it without breaking out in a sweat.
