Autoflex Original SF 505 Pink & Black Driver Shaft

AutoFlex Original SF 505 Pink Driver Shaft

The AutoFlex SF 505 Driver Shaft is a lightweight performance shaft engineered to deliver maximum clubhead speed, increased ball speed, and powerful distance gains through its advanced dynamic profile.

With a 50g construction and designed for stronger swing speeds, it combines high launch, stability, and explosive energy transfer for players looking to optimise performance off the tee.

Overview

The AutoFlex SF 505 is built for golfers who want to push distance further by improving efficiency, timing, and shaft response.

Using AutoFlex’s unique construction, the shaft stores energy during the swing and releases it rapidly through impact, helping generate higher ball speeds without requiring additional effort. It offers a modern approach to driver performance, moving beyond traditional shaft design.

Performance Overview

The SF 505 produces a high launch, mid spin ball flight, allowing players to achieve strong carry distance while maintaining a controlled trajectory.

Its ability to load efficiently and recover with speed creates a powerful release through impact, delivering increased ball velocity and distance. Compared to lighter models, the 505 offers slightly more resistance and stability, making it well suited to players with stronger or more aggressive swings.

The result is a combination of explosive distance, improved consistency, and reliable dispersion.

Key Technologies
