Draw weight is relative to the deflection (or flexibility) of the limbs. Each different sized cam comes with a matched set of limbs to obtain that particular draw weight. Changing the size of the cam considerably will change draw weight in small amounts. Normally within a 10 pound range. But that varies. The usual change would be within 4 or 5 pounds.
Without limbs that flexed though, you would not have enough energy to propel the arrow. Yes the wheels (cams) do provide more energy than limbs alone, but without limbs you would have nothing. You could not have a bow with two unmoving fixed parts connecting a set of wheels. It just wouldnt work. So this makes your response to that gentlemens question, incorrect to an extent.
well, that use to be true. Compounds nowdays don't have much flex at all in their limbs - they don't. I mean, look at this bo, and tell me how much the limbs really flex
No data, Im telling you bud, they have to flex. Even on that AR bow you posted. Those limbs will flex upward or inward or however you want to describe it....(I guess towards each other is the best description)
Each one may only flex about an inch or so, but it flexes. Yes they dont flex as much as the older bows, but they HAVE to flex. Read my description again. It pretty much explains it. If that still doesnt do it for you, just ask, Im pretty sure I can explain it.
The cams and wheels on bows can increase the stored energy, but cant do it without limbs that flex. To say the wheels control the draw weight of a parallel limb bow is incorrect.
Its ok to admit you're wrong, I did it...I know it sucks but...sometimes you just have to.
Im not even sure what this is getting at though. So why are we discussing the stored energy of a compound bow with parallel limbs vs. ???
Have a good one---Matt
