This is the perfect string for older bows or other bows that can not with stand the force that a fastflight string puts on a bow. Our stirings come in red and black. We mark all of our strings by the bow length so the string measures about 4 inches shorter than what the length marked on your bow says. If you are wanting to custom order a string give us a call (812)-276-5430 or email us timberhawkbows@gmail.com
