BLACK EDITION DRIVER SHAFT


black edition driver shaft

The Black Edition shaft series is the highest-end product within the Radian series shaft line-up,
crafted exclusively from Toray's T-1100 carbon fabric as a driver-specific shaft.
Applying the world's first **Kick-pointless** design, it combines extraordinary accuracy,
Active-Trajectory performance that allows golfer to freely control trajectory,
and the powerful trajectory generated by the T-1100 fabric into an
ultra-lightweight, ultra-high-performance shaft.

1. Ultra-High-Modulus T-1100 Carbon fiber Shaft

The Black edition shaft is made exclusively from Toray’s T-1100 carbon fabric
In particular, unlike other products that partially use T-1100 material,
the RADIAN Black edition shaft is made solely from T-1100 fabric,
so it does not suffer from the inconsistent feel or lack of consistency
seen in products that partially use T-1100, and it perfectly conveys the material’s characteristic
solid feel, outstanding distance performance, and stable directionality

. In addition, due to the properties of the ultra-high-elasticity material,
it has the advantage of an exceptionally long lifespan compared to other shafts

2. Approximately 20% Lighter Weight Without a Light Feel

Due to the characteristic of the ultra-high-elasticity material,
the Black edition shaft is manufactured at about 80% of the weight of other products

. In addition, the design maximally converts the high-elastic energy of the material into inertia,
fundamentally preventing the reduction of late acceleration commonly seen in lightweight shafts,
and is designed to maintain a weighty feel through the resonance delay of the volume

3. World's First Kick-Pointless Design and Active-Trajectory Function

The Black edition shaft delivers powerful kick performance without any kick-point —
the world’s first attempt at a kick-pointless design, perfected through countless experiments

. The kick-pointless design eliminates the characteristic of a kick point
where press forwarding occurs during slow entry and lagged tensile occurs during fast entry coexist,
and maximizes the progressive press forwarding characteristic,
making it an advanced feature that guarantees astonishing directional performance
unlike anything experienced before

In addition, by combining an active-trajectory design that integrally links the loading characteristics from the mid-section to the tip with a kick-pointless design,
this shaft activates a forwarding characteristic that responds to the golfer’s swing motion,
enabling golfers to achieve a variety of trajectories according to their intent,
making it an advanced technology shaft

The Black edition shaft is a cutting-edge shaft product that combines
the astonishingly directional kick-pointless design with the Active-Trajectory design that
manipulates trajectory

Misconceptions About Kick-Points

Because people tend to think that the shaft’s trajectory is determined at the kick point location,
it is easy to mistakenly regard the kick point as an essential and important factor

However, from another perspective, paradoxically, the presence of a kick point can also
be interpreted as the presence of the most vulnerable element in the shaft
Because the shaft is the product of active elasticity, but the kick point can also be seen as
the most passive part

Although the result does not necessarily come from the kick point, the claim that
the trajectory must be formed at the kick point is not realistically convincing,
because the trajectory can be obtained through another method of designing the forward ratio.

4. World's First Shafts Separately Supplied for Right-Handed and Left-Handed Golfers

Even for shaft products with the same specifications,
the inherent characteristics present during the manufacturing process
differ from product to product

On the other hand, because the swing directions of left-handed and right-handed hitters are opposite,
a shaft that can accommodate both swing styles is extremely rare even among the same product
Nevertheless, there were no shaft products supplied that distinguished the elements of this part

All Radian series shafts that FITTERSLAB inspects for technical quality are,
through FITTERSLAB’s analysis work for each product
Each product is classified into right-hand and left-hand shafts through precise Spine analyzing
before being manufactured.

5. Shaft Reference Data

Category Lite R S1 S SX X TX TXX Notes
Weight (g) 39 41 44 45.5 49 52 54 58 46" Uncut
Reference CPM 208(216) 223 239 257 273 290 305 320 45" / D2

* Weight
The indicated weight is the product weight before cutting,
so actual production weight will decrease by about 1 to 3 grams.

* Reference CPM
Reference CPM is based on 45 inches (Lite is based on women's 43.5 inches) upon actual production.
It is a reference value and may vary depending on settings such as swing weight and length.
Due to the ultra-high-modulus material properties,
Radian series shafts have CPM values about 3 to 5% higher than comparable classes.

6. Handling Precautions

*Radian series shafts are extremely sensitive to spine setting
Unless in special cases, please maintain the spine applied at the factory;
arbitrary spine changes can lead to a sharp decrease in performance.
Contact FITTERSLAB if you need shot shape modifications or technical advice.

* The recommended maximum tip trimming length for the Black Edition shaft is within 1/2 inch.
Because the flow from the tip is designed with extreme precision,
trimming more than 1/2 inch can affect loading characteristics

* Due to the characteristics of the T-1100 high-modulus material,
it takes some time to break in initially, and it may feel significantly stiffer than the specifications
In return, it offers more than double the durability and lifespan.

* Because Radian series shafts are designed considering toe-down characteristics,
it is effective to set the swing weight 0.5 to 1.5 points lower than comparable products
from other brands.

* To prevent even minute performance changes,
the Black Edition shaft features no painting other than the logo
Consequently, some unavoidable grinding finish marks may be visible,
but they pose absolutely no performance issues.

* At club building, there is no need to strip the tip; simply wipe it clean with a tissue
and bond it directly.

*Radian series shafts provide continuous technical support throughout their lifespan.
If axis verification is difficult due to label damage, or if you have questions to
shaft settings and building, please contact us for technical assistance.


METALLIC EDITION DRIVER SHAFT


Radian metallic edition driver shaft

Metallic Edition Driver shaft series is a premium driver shaft
manufactured exclusively with Toray's 90T carbon fabric.
It is a high-modulus 90T carbon material shaft featuring a solid yet smooth feel,
delivering superior distance performance generated by the material
along with exceptional straightness.

1. Made of Toray's 90T Carbon fiber

Metallic edition shaft, with its solid yet smooth feel, is made from Toray’s 90T carbon fiber
Metallic edition shaft is a material with its characteristic smooth yet tough texture,
offering high stiffness and traction that prevent lagged tensile stress
across a wide range of swing types, from swingers to heaters.

It is designed with a spin-suppressing profile to maintain stable straight-line stability
This is a high-performance shaft developed with a focus on straight-line performance
rather than handling, offering long-distance performance through high rigidity

2. Achieving 15% Weight Reduction

Manufactured using the tough rigidity of 90T carbon,
Metallic Edition Driver shaft weighs 10 to 15% less than other products of equivalent stiffness,
creating a head-speed enhancement effect.

3. Designed to Stable Directional Control

Metallic Edition Driver shaft adopts a Bridge-style forwarding design,
transmitting high-modulus energy without loss to
maximize head speed and prevent late-stage acceleration drop-off.

Consequently, unlike the powerful feel of the Black Edition Driver shaft,
it is built with a forgiveness-focused design that maintains a soft feel while securing
mid-trajectory long distance performance and directional stability comparable to the
Black Edition Driver shaft, all while minimizing side-spin to the greatest extent possible.

Following the same rationale as the Black Edition Driver shaft's kick-pointless design,
it connects the loading characteristics from the mid-section to the tip using a
Bridge-type wide kick design to prevent press-forwarding and lagged tensile phenomena.

Furthermore, by appropriately combining the signature
press-forwarding characteristics of the Radian series shafts,
it is engineered to suppress side-spin and maintain a stable shot shape
even during swing and maneuver execution errors.
