Carbon Arrow Spine Guide for Compound and Recurve Bows

What arrow spine means

Arrow spine describes how much an arrow shaft flexes under load. A lower spine number usually indicates a stiffer shaft, while a higher number indicates more flex. Choosing the correct spine helps the arrow leave the bow cleanly, group consistently, and carry the point weight you plan to use.

Start with your bow and draw setup

Before buying carbon arrows, write down your bow type, peak draw weight, actual draw length, arrow length, and point weight. Compound bows with aggressive cams often need a stiffer shaft than a recurve bow at a similar marked draw weight. Longer arrows and heavier points also increase the amount of flex during the shot.

Use the manufacturer chart as your baseline

A spine chart is the safest starting point because every shaft model is built differently. Find your draw weight and finished arrow length, then choose the recommended spine range. Common options such as 300, 340, 400, 500, and 600 cover many compound, recurve, target, and hunting setups, but the right value depends on the complete bow-and-arrow system.

Factors that can require a stiffer arrow

• Higher draw weight or a longer draw length
• A longer finished arrow
• A heavier field point or broadhead
• A high-energy compound cam

If your setup falls near the edge of two chart groups, check the bow and shaft maker recommendations before choosing. Do not shorten carbon shafts or change components unless you understand how the change affects dynamic spine and safety.

Compound bow versus recurve bow selection

Compound archers should use the bow’s measured peak weight and actual arrow length, not estimates. Recurve archers should consider the weight measured at their personal draw length because the marked limb weight is commonly measured at a standard draw length. A longer draw can raise the real holding weight and change the suitable spine.

Check arrow length, straightness, and components

Spine is only one part of a reliable arrow. Match shaft length, inside diameter, nocks, inserts, points, and vanes as a complete system. Inspect every carbon shaft before shooting. Stop using an arrow that shows cracks, splinters, unusual noise, or damage after an impact.

Explore Link Sports carbon arrows

Link Sports offers carbon arrows in spine 300, 340, 400, 500, and 600 for a range of compound and recurve setups, plus 32-inch carbon arrow shaft options in spine 400, 500, and 600. Review the product specifications and compare them with your bow or shaft manufacturer chart before ordering.

Quick checklist before you buy

1. Confirm bow type and measured draw weight.
2. Measure actual draw length and planned arrow length.
3. Choose point weight and components.
4. Compare the complete setup with a spine chart.
5. Inspect and test arrows safely before regular use.

The best carbon arrow is not simply the stiffest or lightest option. It is the shaft that matches your bow, components, shooting style, and the manufacturer’s safety guidance.
