Let’s take a closer look at the Callaway Big Bertha B21 driver in this review.
In the Big Bertha driver family, the Big Bertha B21 is the newest member. The club combines Callaway’s latest technologies, such as Flash Face, Jailbreak, and T2C Carbon Crown, while utilizing an ultra-low forward CG for high launch, low spin, and long distance.
As well as that, the Big Bertha B21 has an internal draw bias that’s designed to keep the big miss from becoming a slice.
Big Bertha drivers are characterized by straighter shots, more distance, and exceptional forgiveness. With Callaway’s latest technology, the B21 offers all of these benefits and more.
Flash Face SS21
Let’s start with the latest Flash Face iteration: SS21. The A.I. face was created by combining tens of thousands of prototypes using a supercomputer and machine learning.
By producing faster ball speeds over a wider area of the face, the Flash Face SS21 increases mishit distance.
Ultra-Low CG & Draw Bias
In the Big Bertha B21, the center of gravity (CG) is located low and forward. Combined with a high launch, this also produces a lower spin, resulting in monster distances.
In addition, the Big Bertha B21 has an internal weighting that promotes a draw. In other words, if you struggle with a slice, you will be able to stop making the big mistake of leaving the right side of the golf course out of your game. With this club, you can hit the fairway and gain distance as well.
Jailbreak & T2C Triaxial Carbon
It was first featured in the Rogue driver, where titanium bars connect the crown and sole vertically. As a result, more impact load is placed on the ball’s face, which further enhances the ball’s speed.
It is a triaxial carbon fabric that is very light and allows for maximum weight savings. A higher moment of inertia (MOI) is achieved by redistributing this weight in the head.
Light & Strong Face Architecture
Big Bertha B21’s face architecture is stronger, lighter, and stronger than traditional titanium. By optimizing the ball speed across the entire surface, performance is improved.
There are three lofts available for the Big Bertha B21 driver at 460 CC: 9°, 10.5°, and 12.5°.
Women can also choose from the Big Bertha REVA driver, available in lofts of 10.5° and 12.5°. In addition to its core technologies, this driver features lofts, swing weights, shafts, head shapes, and grips tailored to the specific needs of women.
Big Bertha B21 has an adjustable loft and lie thanks to the Optifit hosel. (A range of 3° is available): -1, +1, 0, and +2. A total of 8 possible configurations are possible with N (neutral) and D (draw).
It comes with a Callaway RCH graphite shaft (40/50/60), and a Golf Pride Tour Velvet 360 grip. Shafts can be customized.

Pros and Cons
How does the driver perform?
The following sections will be devoted to comparing the Big Bertha B21 to Callaway’s latest offering from the MAVRIK line, the MAVRIK MAX.
Compared to the MAVRIK, the Big Bertha B21 has almost identical raw ball speed numbers. Since both devices have Flash Faces, Jailbreaks, and similar speed-boosting technologies, this isn’t surprising.
Several factors will affect distance beyond that. The Big Bertha B21 is ideal for people who struggle with slices and often hit straighter shots. The more power you put into the shot, the further it will go.
In addition, spin plays a role. Golfers will see more carry, rollout, and total distance with the Big Bertha B21 since it produces less spin than the MAVRIK MAX (along with a higher launch).
Probably the longest driver most recreational golfers have ever played is the Big Bertha B21. This is because the driver suits low-medium swing speeds and fade ball flights, which most amateurs have.
The Big Bertha B21’s technology increases ball speeds in mis-hit areas of the face, making forgiveness closely related to forgiveness.
It is very forgiving in both directions (draw bias helps here as well). Based on my testing, the Big Bertha B21 has superior forgiveness to the standard MAVRIK, but just falls short of the MAVRIK MAX.
There should be more variability at impact due to the forward CG position and the lower spin. There is a tradeoff associated with a lower spin.
Despite that, this is your choice if you want a low-forward CG driver with low spin but the greatest amount of forgiveness.
With the Big Bertha B21, you will likely hit a lot of fairways unless you’re a natural hooker.
Having the stock shaft on the Big Bertha B21 driver allows the driver to feel great through the swing and enables you to make great contact with the ball. It was great to hit baby draws consistently after hitting straight or, at most, a slight fade ball flight.
It is important to keep in mind that your natural ball flight should take into account the inherent draw bias of the Big Bertha B21.
It is still possible to shape the ball quite well, so adept golfers can execute a fade despite the bias.
On the other hand, shots with the Big Bertha B21 will launch higher and be more penetrating in the right conditions than those with the MAVRIK MAX.
What about look, sound & feel?
A resemblance between the Big Bertha B21 and the Big Bertha Fusion can be seen in the B21’s unique look.
There is a greater difference between the MAVRIK MAX and this model, the face of which is more rectangular and the back of which is more triangular. Blue dominates the color scheme, along with red and gray accents.
The Big Bertha B21 has a better color scheme than the MAVRIK, which is orange. Both appeal to me. In addition to the sole design, I like the way the Big Bertha logo is centered in the middle of the shoe.
As well, the shape of the head conceals a significant offset on the Big Bertha B21. With this driver, golfers won’t be bothered by its appearance at the address but will be able to enjoy its performance.
The Sound & Feel
When you swing the Big Bertha B21, you feel like you’re swinging a premium club despite its lightweight. Through impact, I was impressed with its solidity and explosiveness.
There is a nice balance between being loud and muted in the sound of the Big Bertha B21. I would describe it as crisp.
The sound is similar on the heel and toe as you move away from the face. Despite this, the Big Bertha B21 feels noticeably worse, which might surprise some since the car isn’t advertised as a player’s car.
Bringing down the spin sacrifices some stability on mis-hits, so I think it has more to do with its weight distribution. As a result, you can improve your consistency by receiving clearer feedback.
Callaway’s latest innovations, including the Flash Face and Jailbreak, make the Big Bertha B21 the most powerful Big Bertha yet.
It can cover a great distance. For golfers who struggle with a slice, it’s a must-try because of its amazing feel in the sweet spot.
The Big Bertha B21 is also a great choice if you have a fast swing speed since it takes advantage of the low spin property better. If you would rather have a more forgiving, higher-spin machine, you should take a look at the MAVRIK MAX instead.
