Using the highest quality string material for Great Northern Bow Strings, BCY X is the leader in bow string technology. The end servings are BCY 2X and the nock serving is BCY 62 Braid XS. We believe that this combination produces the best string/cable quality on the market. ** To determine the length of string your bow requires measure the length of the actual length of your bow tip to tip and subtract 4.5 inches. This will generally be the string length for your bow** ** To calculate AMO STRING LENGTH to standard measurement subtract 4" from AMO number to get actual measured string length. I.E. AMO 58 = 54" measured string length. Strings sizes in inches = Length/number of strands (54-16 = 54" - 16 strand)
