What do the numbers on a carbon arrow mean?
Aluminum and carbon-fiber combination arrows are measured by spine deflection. A smaller number means that the arrow has a stiffer spine. For example, 3-60/340 means three wraps of carbon-fiber with an aluminum core tube diameter of 60 and a spine stiffness rating of 340.
What does a 340 arrow mean?
As with combination arrows, a smaller number means the arrow has a stiffer spine. Therefore, a value of 340 indicates a stiffer and heavier spine while a value of 500 indicates the lightest and most flexible spine.
What does 350 spine mean in arrows?
The spine rating of an arrow is simply a measurement of its stiffness. The same Easton arrow comes in a variety of stiffness: the lower the number, the stiffer the arrow. For example, a 330 arrow is stiffer than a 500 spine arrow.
What happens if an arrow is too short for the bow?
Bending, known as “archer’s paradox,” occurs when an arrow is released from the bow. Spine strength must be matched to bow draw weight. If your arrows are too lightly or heavily spined for your bow, the “archer’s paradox” movements will be extreme, resulting in poor arrow flight and loss of accuracy.
What do the numbers mean on an arrow shaft?
A smaller number means that the arrow has a stiffer spine. For example, 3-60/340 means three wraps of carbon-fiber with an aluminum core tube diameter of 60 and a spine stiffness rating of 340. Carbon arrows also are labeled to indicate their spine deflection. The most common spine sizing values are 340, 400, and 500.
What is the sizing of a carbon Arrow?
Carbon arrows also are labeled to indicate their spine deflection. The most common spine sizing values are 340, 400, and 500. As with combination arrows, a smaller number means the arrow has a stiffer spine. Therefore, a value of 340 indicates a stiffer and heavier spine while a value of 500 indicates the lightest and most flexible spine.
What’s the difference between aluminum and carbon fiber arrow shafts?
A thicker shaft provides greater stiffness. Aluminum and carbon-fiber combination arrows are measured by spine deflection. A smaller number means that the arrow has a stiffer spine. For example, 3-60/340 means three wraps of carbon-fiber with an aluminum core tube diameter of 60 and a spine stiffness rating of 340.
What is the deflection of a carbon Arrow?
Easton’s familiar carbon arrow spine sizing system (500, 400, 340, 300) is basically the arrow’s spine deflection x1000. So a 500 shaft is a .500″ deflection. A 340 Easton shaft is a .340″ deflection and so on. So forgiving the shift of the decimal, the Easton spine sizing system matches up nicely with actual spine deflections.
