follows the traditional Project X alphanumeric coding system, where "7" denotes the weight class and "C" indicates the specific flex and launch profile. Shaft specs - Club Fitting - Team Titleist project x 7c3 driver shaft specs

Let’s get straight to the technical specifications you are looking for. Please note that weights and frequencies can vary slightly based on raw length and adapter trimming, but the standard "Retail" specs are as follows:

Based on GCQuad and TrackMan testing of the Project X 7C3 installed in a 9.5 or 10.5 degree head: Marco muttered to himself, “This isn’t counterbalanced

A new line of text glowed under the specs:

At exactly 119 mph of clubhead speed, the shaft would enter a harmonic oscillation. The tip wouldn’t just kick—it would whip sideways . Launch angle would drop by 4°, spin would jump by 1,200 RPM. The ball would start straight, then dive left like a wounded duck. The tip wouldn’t just kick—it would whip sideways

Do not confuse the 7C3 with the original Project X (non-C series) which had codes like 6.0 or 7.0. The “C” series is smoother and slightly higher launching than the original steelfiber-like Project X.
