Callaway Big Bertha B21 Range of Golf Clubs

Posted by GolfBox on 24th Sep 2020

Sometimes in golf you just have to play the cards you’ve been dealt and decide to make the most of the swing you’ve got. Sure, it might contain a few weird moves and produce the odd massive miss that comes out of nowhere, but somehow you learn to live with it and play golf your way.

It’s a similar sentiment that is echoed throughout Callaway's NEW Big Bertha B21 line-up, which aims to maximise distance no matter how you swing it.

Built around the premise that the simplest way to add distance to your game is to hit the ball straighter, the collection of drivers, fairway woods, hybrids and irons is dedicated to reducing both the side spin and back spin that results from coming across the line and getting steep, while guarding against those "big misses".

Engineered for effortless launch and maximum distance, the Callaway Big Bertha B21 line-up almost assumes you won’t be taking lessons to correct your slice - so, the clubs do all the hard work to maximise your game with the swing you’ve already got.


High-launching and draw biased for straighter ball flights and more distance.

Wood & Hybrid

Easy to launch and ultra-forgiving for confidence boosting performance.


Flash Face & Tungsten weighting delivers ball speed and distance.    


It’s easy to appreciate what the new Callaway Big Bertha B21 driver brings to the game for players who have a tendency to get steep and come across the target line, spraying the big dog all over the course.

Chances are you frequently start walking towards the right rough or trees, afflicted with a slice you just can't get rid of. Or you compensate for that slice by aiming way left to find the fairway, and when the ball lands it runs across the fairway instead of along it.

The new Big Bertha B21 driver counteracts the curse of the banana ball with a draw-biased design that will straighten up your ball flight, add distance and reduce the occurrence of those "round-wrecking" misses off the tee.

With a low and forward centre of gravity to reduce the level of back spin and side spin that rears its ugly head as a slice, the Big Bertha B21 driver doesn't pass judgment on your swing; instead it launches with incredible ease, offers tonnes of forgiveness and generates straight-up distance no matter how you swing it.

Big Bertha B21 Tech Flash Face

Big Bertha B21 Flash Face SS21

Callaway’s supercomputer has been at it again, using machine learning to refine the face of the Callaway Big Bertha B21 driver.

The resulting SS21 Flash Face is ultra-effective at extracting maximum ball speed and distance, even if you’re miles away from the sweet spot.

Super-Strength Titanium

Callaway opted to use a super sturdy titanium in the Big Bertha B21 driver face to optimise speed, forgiveness and spin.

The new titanium is lighter than regular titanium and was able to free up discretionary weight to be placed where it can create extra forgiveness and distance.

Big Bertha B21 Driver Tech Jailbreak

Jailbreak Tech

Callaway’s Jailbreak technology has been incorporated into the Callaway Big Bertha B21 driver to strengthen and stiffen the club head. Two internal Jailbreak rods link the sole and crown to support the head and direct energy into the ball at impact for extra ball speed.

Big Bertha B21 Driver Tech Draw Bias

Low Spin & Draw-Bias

The Big Bertha B21 driver fights a slice with an internal draw bias which is implemented into the driver’s internal design. It straightens up ball flights, while the driver’s low and forward CG produces high-launching, low spinning, and significantly longer drives.

Some golfers just aren’t fans of fairway woods, with inconsistent contact and low, diving ball flights the chief culprits.

With players shunning what should be one of the safest clubs in the bag, Callaway have made the new Big Bertha B21 fairway woods the most user-friendly in golf.

No matter how you swing them, Big Bertha B21 fairway woods offer effortless launch and distance and are also highly forgiving from all over the new SS21 Flash Face.

Sharing many of the key technology benefits as the driver, Big Bertha B21 fairway woods will straighten you up out on the course and get you back on the fairway wood bandwagon.

Big Bertha B21 Fairway Tech Flash Face

SS21 Flash Face

The new Flash Face SS21 has been designed with the aid of AI to generate hot ball speeds, high launch, extra carry and breathtaking distance from every part of the B21 fairway woods’ face.

It works together with the oversized Big Bertha shape to provide effortless length and extreme forgiveness from any lie.

Offset & Progressive Shaft Lengths

For the first time in a Callaway fairway wood, Big Bertha B-21 fairway woods feature offset to promote a drawing ball flight and mitigate slices.

Slightly shorter shaft lengths are also used in the fairway woods, with the small loss in clubhead speed more than made up through better and more consistent contact at impact.

Big Bertha B21 Fairway Tech Offset

Shallow Face & Lower Leading Edge

Sporting a shallower face, B21 fairway woods are easy to launch and are designed to be ultra-consistent out of any lie. A lower leading edge offers smooth contact through all turf types and activates ball speed from low ball strikes on the face, a common contact area among higher handicap golfers.

Jailbreak Technology

Callaway’s famed Jailbreak technology stiffens the body of the clubhead via two internal bars, which join the lightweight triaxial crown to the sole. Jailbreak directs maximum energy into the ball at impact to elevate speed and distance.

Prepare to make some room in your bag, because when the new Callaway Big Bertha B21 hybrid is released, it’ll be going straight into the bag.

Like the entire B21 range, the versatile new hybrids are designed to create distance no matter how you swing the club, with a focus on straightening up ball flights and eliminating those huge misses that spin offline.

Sporting a slightly larger head, the hybrids are able to cram all the best Callaway tech inside, such as Jailbreak and AI-designed Flash Face, while over 70g of tungsten weighting is positioned internally to keep the centre of gravity low for superior performance and a high-MOI that protects ball speed when strikes aren’t out of the centre.

And with effortless launch and increased offset, Big Bertha B21 hybrids will boost your confidence from any situation you encounter out on the course, including chipping.

The hybrids are designed to integrate seamlessly with the Big Bertha iron set and are available from a 3-hybrid all the way up to an 8-hybrid.

Fast Ball Speeds From Flash Face SS21

Fast ball speeds across an expansive area in each model and loft, with our advanced A.I.-designed Flash Face. So you’ll hit it long, even if you miss the center of the face at impact.

Increased Offset

Additional offset helps square the club face at impact to produce straighter, and longer, shots out of any on-course scenario.

Big Bertha B21 Hybrid Tech Jailbreak

Increased Ball Speed & Easy Launch

Two internal Jailbreak bars connect the sole and crown, so the face can take on more of the load at impact. For higher MOI in a forgiving shape, Callway used a significantly lighter carbon crown so we can redistribute weight.

Big Bertha B21 Hybrid Tech Tungsten Weight

Dual MIM’ed Tungsten Weighting

Big Bertha B-21 hybrids have dual internal Metal Injection Moulded (MIM) tungsten weights to optimise the centre of gravity and enhance launch and trajectory.

Long, straight, forgiving and designed by artificial intelligence, the new Callaway Big Bertha B21 irons are perfect for swings that are not.

They are supercharged game improvement irons that align closely to the Big Bertha heritage of large head sizes and confidence-inspiring shapes.

Designed to improve the golf of average golfers, B21 irons feature several supportive technologies that generate ball speed no matter where you hit it on the face.

An AI-designed face works in tandem with the new larger head size to maximise ball speed across a wide area of the face while a greater amount of high-density Metal Injection Moulded (MIM) tungsten makes the irons easier than ever to launch.

And with wide soles to stop the irons digging into the turf before the ball, generous offset to help close the face at impact and a thick, confidence-inspiring topline, the Big Bertha B21 irons set a new benchmark for performance and distance for players who need it most. Tour irons they are not, but they will get the job done no matter how you swing it.

Tungsten Energy Core

High-density tungsten weights, shaped uniquely according to head size and loft, are slotted into every Mavrik iron to deliver optimal launch and trajectory.

Urethane Microspheres

A slice of urethane populated with microspheres is inserted into the head of every Mavrik iron to absorbing vibrations for a pure and consistent feel.

A.I. Designed Face

Each iron has its own A.I designed Flash Face Cup, unique to its loft, to propel the ball further while maintaining spin, descent angle and trajectory.
