Project X Evenflow 5.5 Green 65g Regular Flex Driver Shaft

The Project X EvenFlow Green 5.5 65g Regular Flex Driver Shaft is designed to deliver an exceptionally smooth loading sensation, efficient energy transfer, and dependable control throughout the swing.

Built around the flowing bend profile that defines the EvenFlow family, the 5.5 Regular flex provides a responsive yet controlled feel, while the 65g-class construction offers excellent clubhead awareness and stability for golfers seeking balanced, confidence-inspiring driver performance.

Overview

The Project X EvenFlow Green 5.5 65g Regular is designed for golfers who want their driver shaft to feel smooth, connected, and naturally responsive without sacrificing stability.

The EvenFlow family was developed around a distinctive design philosophy: allowing energy to transfer progressively throughout the shaft rather than concentrating stiffness or movement within one particular section.

This creates the characteristic EvenFlow feel — a fluid loading sensation from the handle through the midsection and into the tip, helping the shaft work naturally with the golfer's swing.

In the 5.5 Regular configuration, that profile provides an excellent balance between responsiveness and control.

The shaft loads progressively during transition, making it easier to maintain rhythm and timing, while the Regular flex provides enough resistance to remain stable as clubhead speed increases.

The 65g-class construction adds a reassuring amount of substance and clubhead awareness, making it particularly attractive to golfers who prefer a more connected driver setup rather than an ultra-lightweight shaft.

The result is a driver shaft built around smooth feel, efficient speed, and predictable all-round performance.

Performance Overview

The EvenFlow Green 65 5.5 is designed around a smooth, balanced performance profile, producing a playable driver trajectory that combines useful carry distance with dependable directional control.

Its defining characteristic is the way it loads throughout the swing.

During transition, the EvenFlow profile bends progressively rather than producing an abrupt kick from one isolated area. This creates a fluid sensation that helps golfers maintain tempo while transferring energy efficiently into the clubhead.

The 5.5 Regular flex provides a little more resistance than the 5.0 Senior version while retaining the smooth character that defines the EvenFlow family.

For golfers with moderate swing speeds, this creates an appealing combination: enough responsiveness to feel the shaft working throughout the swing, but enough stability to prevent it from feeling loose when additional speed is applied.

The 65g-class profile also provides greater clubhead awareness than lightweight 50g alternatives, helping create a connected sensation from takeaway through impact.

The result is a shaft that delivers:

• Exceptionally smooth and progressive loading
• Responsive Regular flex performance
• Balanced, playable driver trajectory
• Efficient energy transfer throughout the swing
• Greater clubhead awareness from the 65g-class profile
• Stable and connected feel through impact
• Consistent and predictable dispersion

Key Performance Characteristics

EvenFlow Bend Profile

The defining characteristic of the EvenFlow family is its smooth and progressive bend profile.

Rather than creating a pronounced stiffness change within one particular section, the shaft is designed to transfer energy fluidly throughout the swing.

This produces the connected, flowing sensation that gives the EvenFlow family its name.

Smooth 5.5 Regular Flex

The 5.5 profile provides an excellent balance between responsiveness and stability for golfers with moderate swing speeds.

It allows the shaft to load naturally while providing additional resistance compared with the softer 5.0 Senior version.

65g-Class Construction

The more substantial shaft weight provides additional clubhead awareness and control compared with lighter driver shafts.

This makes it particularly attractive to golfers who prefer to feel the shaft and clubhead throughout the swing.

Responsive Energy Transfer

The progressive profile allows energy to move smoothly through the shaft during transition before releasing naturally through impact.

Versatile Driver Performance

Rather than being designed solely around an extreme launch or spin condition, EvenFlow Green provides a playable performance window focused on smooth feel, useful trajectory, and consistent control.

Player Profile

This shaft is ideally suited to golfers who:

• Have moderate driver swing speeds
• Prefer a 5.5 / Regular flex shaft
• Have a smooth to moderate transition
• Value feel and rhythm throughout the swing
• Prefer a 65g-class driver shaft
• Want greater clubhead awareness than a lightweight shaft
• Find Stiff flex profiles unnecessarily demanding
• Want more stability than a Senior flex shaft
• Prefer smooth energy transfer rather than an aggressive kick
• Want balanced and predictable driver performance

The 5.5 Regular flex is particularly suited to golfers who want a responsive shaft that loads naturally while providing enough structure to remain controlled through impact.

Tempo, transition, release pattern, driver head weight and finished playing length should also be considered when choosing the ideal setup.

Why Choose the Project X EvenFlow Green 5.5 65g

The Project X EvenFlow Green 5.5 65g is an excellent option for golfers who prioritise smooth feel, natural loading, and dependable control from their driver shaft.

Its 5.5 Regular flex occupies a useful middle ground.

It provides more resistance and stability than the softer 5.0 Senior version without requiring the golfer to load the shaft as aggressively as a Stiff flex profile.

Combined with the 65g-class construction, this creates a shaft that feels substantial and connected throughout the swing while remaining smooth and responsive.

Most importantly, the EvenFlow profile allows the golfer to generate speed naturally. Rather than relying on an abrupt kick or excessively active tip, energy flows progressively through the shaft before releasing through impact.

With this shaft, you can expect:

• Exceptionally smooth Regular flex loading
• Balanced and playable driver trajectory
• Efficient energy transfer throughout the swing
• Greater clubhead awareness from the 65g-class profile
• Responsive feel without excessive movement
• Stable clubhead delivery through impact
• Consistent and predictable ball flight
• The distinctive smooth feel of the Project X EvenFlow family

This is a smooth-loading performance graphite driver shaft for golfers who want to combine the responsive feel of Regular flex with the additional control and connected sensation of a 65g-class profile — delivering balanced, confidence-inspiring performance through the distinctive Project X EvenFlow design.
