Callaway reveals Great Big Bertha Epic and Sub Zero fairway woods

Like Callaway’s Epic drivers, the Great Big Bertha (GBB) Fairway Woods employ propriety triaxial carbon composite material for forgiveness, power and accuracy.


The carbon crown, next-generation Hyper Speed Face and Speed Step technologies work together for more ball speed and distance.

Weight saving through redesigned crown

Epic’s triaxial carbon crown weighs 5.8g, making it 78% lighter than a steel crown. The saved weight is redistributed into strategic locations within the head to increase MOI (11% higher than XR 16 fairway woods) and lower CG.

Refined Hyper Speed Face Cup

A refined Hyper Speed Face Cup technology increases the area of the face that delivers fast ball speed.

Now, the thin and flexible rim around the inner side of the face flexes and releases more uniformly and efficiently at impact to further increase ball speed across the face, especially towards the bottom.

Latest Speed Step Technology

Head speed gets an additional boost from the latest version of Callaway’s Speed Step technology, originally developed in partnership with Boeing.

Located on the crown, the Speed Step improves airflow to encourage more swing speed and distance without extra effort.

OptiFit Adjustability

An OptiFit Hosel allows for further fine-tuning in the fitting process to aid precise shot-shaping and adjustment of lofts up and down if required.

Loft and shaft options to suit all golfers

A broad line-up of lofts are available, ranging from a strong 3+ wood (14*) to the versatile Heavenwood (20.5*).

With the new Epic drivers, we are offering the most comprehensive stock shaft lineup in Callaway history. We have offerings from the 40g class all the way through the 80g class, in a variety of weights, flexes and torques. Driver and fairway wood shafts are interchangeable for maximum flexibility.

Diamana M+ Green – Mitsubishi’s first ever sub-50g Diamana offering. Diamana has been a staple on Tour for many years, and led the PGA and European Tour in wins in 2016. This shaft will be available in the 40g and 50g classes

Project X HZRDUS – features high modulus T800 carbon fiber and is offered in the 50g and 60g class. HZRDUS has quickly made a name for itself on Tour and has been the #1 played model during the 2016-2017 PGA Tour season

Fujikura Pro Green - a popular choice on Tour. This shaft features a stiffened mid and tip section for stability. It is offered in the 60g and 70g classes and we expect it will be a popular stock option for the Epic Sub Zero driver

Aldila Rogue M•AX – new version of the popular Rogue series of shafts. This shaft features a full length multi-axial carbon weave and plays with quite low torque. This will be available as stock in the 60g & 70g classes as well as in the 80g class for the Epic Fairways

Price: £279
Available: 27 January

Available Lofts: 3+W (14°), 3W (15°), 5W (18°), Heavenwood (20.5°), 7W (21°), 9W (24°). All available in left hand options except 3+W, which is custom only

Callaway Great Big Bertha Epic Sub Zero Fairway Wood

Replacing the Big Bertha Alpha 816, the Epic Sub Zero fairway wood is designed for players that want to fine tune their spin rates, and it has a more refined shape which will suit the eye of better players. 

Sharing much of the same technology as the GBB fairway woods – triaxial crown, new Speed Face Cup, Speed Step Technology, more shaft options, OptiFit Adjustability – this product also features interchangeable weights to dial in spin and trajectory.

Two interchangeable weights in the sole, toward the front and back, adjust launch and spin rates ±350-400 rpm.

The heavier weight (22g) up front and the lighter weight (3g) in back for low-spin, lower launch conditions for a lower, flatter trajectory. Putting the heavy weight in back delivers mid-level spin, a higher launch angle and raises MOI for easier launch.

Available:27 January

Available Lofts:13.5°, 15° and 18°. All available in left hand options except 18°, which is custom only
