maybe I'll call bowtech tommorrow and see what they say about the axle to axle.I took my string and cable off and measured them.the cable was ok.I had to take about 5 twists out of my string.this is a new string I got and after shooting for a while it did stretch a little I had put a few stwists back in it.and the cable too.I just put a few to many,but its in perfect time now.do I attach a piece of thread to the outside of the axle and measure up to the string?if so I would have to take the E clips off.
