X 7c3 Driver Shaft Specs | Project

Most shafts fight spin. This one fed it—in a controlled way.

The Tour player loved it. He said it let him “feel the miss.” But when a second player—a beloved major champion—tested it, the shaft snapped at the 7C3 silk-screen band. Not broke. Shattered . Carbon fiber sprayed across the range like confetti. project x 7c3 driver shaft specs

The 7C3 doesn’t exist. You won’t find it on the USGA conforming list, on eBay, or in any fitter’s matrix. But if you ever meet a grizzled club tech with a burned right hand and a driver that sounds like a tuning fork at impact—don’t ask to swing it. Most shafts fight spin

That night, he built a driver: a 9° SIM head, hotmelted to 204g. He tipped the 7C3 0.5” (against Lena’s screaming advice). He gripped it with a Tour Velvet Cord. He said it let him “feel the miss

She explained. In 2012, True Temper developed the 7C3 for a single player: a young, volcanic South African who swung 128 mph. He wanted a shaft that felt loose in transition but dead at impact. The engineers created the double-kick profile. But during robot testing, something went wrong.

Marco didn’t listen. He had a raw blank of the original 7C3—the only one left—sitting in a tube behind his workbench. He’d bought it years ago at a surplus auction, thinking it was a standard Hzrdus.

46.25” raw (Tour issue standard was 46.0”) Butt OD: 0.620” (thicker than any retail) Tip OD: 0.335” (standard) Tip-to-Balance Point: 22.75” (this was the anomaly. In a normal counterbalanced shaft, the balance point is high—near the grip. In the 7C3, it was exactly 1.25” lower than the mathematical model predicted.)
