Shaft flex affects how much the shaft bends during your swing — which can impact accuracy, distance, and feel.

Common flexes include:

L (Ladies): Very flexible, for slower swing speeds

A (Senior): Slightly stiffer, still great for slower swings

R (Regular): Moderate flex — most common for casual golfers

S (Stiff): Less bend — better for faster swing speeds

X (Extra Stiff): Minimal flex — designed for very high swing speeds

You may also see numerical flex ratings like 5.0, 5.5, 6.0, 6.5, or 7.0, especially on shafts from brands like Project X:

5.0 ≈ Regular

5.5 ≈ Firm (between Regular and Stiff)

6.0 ≈ Stiff

6.5 ≈ Strong Stiff / Tour Stiff

7.0 ≈ Extra Stiff

These numbers offer a more precise fit for golfers dialed into their swing tempo and speed.

Loft affects how high the ball launches and how much spin it has.

For drivers, common lofts include:

9°: Lower launch, less spin — better for fast swing speeds

10.5°: Balanced launch and spin — works well for most golfers

12°: Higher launch, more spin — great for slower swing speeds and a common choice for many female golfers

Choosing the right loft helps optimize distance and consistency based on how you swing.
