The material used to make these strings is B50 which is a polyester allowing the string to stretch and come back to its length cushioning the limbs with every shot.
How to Measure Your Bowstring
"Example: A Bow String Master designated as AMO 66” (bow length) will have an actual length under tension of 63”. That's the "rule". However, many traditional bows--old or new--do NOT follow AMO/ATA specs so to be more accurate its best to measure the string if its available. And remember when measuring a recurve style bow you need to follow the curve of the limbs.
When Measuring put a nail in a board and put lower end loop over nail then start with your total length A (0-54") Then measure the lower end serving B (0- 5") Then measure the center serving from the lower end of loop to start and end of center serving. C (23 " to 30") and then measure the other end serving length if different. D (0-5"). Bottom loop 1.25" Top loop 1.75"
For center serving we use Crown Serving so you get a smooth finger release, color choices to choose from are Black, Hunter Green and Gray.
