From a number of Tiger owners' experiences when using a solid 1" front bar,
the weakest point is actually the lower control arm. The slot is very close
to the front edge of the A-arm, and has simply ripped out on occasion.
However, I've yet to hear of anyone breaking either the clamp or the A-arm
when using a 7/8" bar.
