Carbon Composite Lacrosse Shafts

Carbon composite lacrosse shafts

Most people call these carbon fiber shafts. The more accurate term is carbon composite, and the difference is worth thirty seconds of your time before you spend money.

Carbon fiber on its own is thread. It has enormous tensile strength along its length and essentially none across it — a loose bundle of carbon fiber has no structure at all. What makes a shaft is carbon fiber plus epoxy resin, cured together: the fiber carries the load, the epoxy holds the fibers in position and transfers force between them. That combination is a composite. How the fibers are oriented, how many layers go down, and how the resin is cured matter as much to how a shaft performs as the carbon itself.

So when a brand advertises "carbon fiber," they're naming one ingredient. Every Primo shaft on this page is a true carbon composite — not fiberglass, not a filled blend. Here's what that gets you, and what it costs you.

Why carbon composite

  • Lighter than alloy at the same strength. Our lightest is 145g. Nothing in metal gets there without giving up wall thickness.
  • Flex adds snap. The layup loads and releases on a shot in a way stiff alloy doesn't.
  • Won't dent or bend. No permanent divots from a check.
  • Grip textures metal can't hold. 3D raised checkered and soft tack finishes, so most players never tape.

The honest trade-off

When carbon composite fails, it breaks. It holds and holds and then it's done — usually mid-check, usually with no warning. Alloy dents instead, and a dented shaft still finishes the game.

That's why we build heavier, thicker-walled models like the 210 and 425 for players who take contact, and why we also sell a scandium-titanium line for players who'd rather have a shaft that bends.

Pick your weight

  • 145g — attack and offensive middies who want the fastest hands available. 30".
  • 155g — on clearance at $59.99. 30".
  • 175g — the balanced pick and our most popular short stick. 30".
  • 210g — thicker walls, more material in the impact zone. Box, short stick D, anyone who breaks shafts. 30".
  • 350g–450g — 60" long poles for LSM and close defense. The 425 is the pick if you've snapped a pole before.

Legality and warranty

All Primo shafts are NFHS and NCAA legal. Warranty runs 90 to 365 days depending on model — heavier shafts carry longer coverage. See the full warranty table. Every shaft also carries a 30-day trial guarantee.
