Does anyone know if the string and cable lengths that are listed for bows if those are the untwisted length and then you add twists to them. Or are they the finished twisted up lengths. If they are the untwisted lengths how do you know how many twists to put in them?

The length should be the finished product as it goes on the bow. Whether it's twisted or not is a matter of who makes the string. If you get a gander at any of the GOOD after market strings you'll notice that they often have one revolution (twist) for each 1 1/2" to 2" of length.

For example, if you shoot a single cam bow with a 100" string then it should normally have 50 twists or more. Most generic factory strings may have about 10 or so. That's one of the reasons (among others) that they creep so badly.

it depends too.

hoyt has given untwisted lengths for a long time, but i've heard this yr they'll give finished lengths. i've seen the new lengths - and there are no signs to me they've changed.

parker has given untwisted lengths for a long time too. they've just recently started keeping finished lengths on file in the tech department.

bowtech gives good finished lengths (provided they haven't changed them from the sticker w/out telling anyone)

mathews, well well mathews. there is no rhyme or reason to the lengths they publish. they're not finished lengths, they're not untwisted lengths, they are only numbers that are probably w/in 1" of what the actual finished lengths are.
