Every time I turn around, it seems like Callaway is coming out with a hot new driver. Most recently, I had the chance to hit the drivers in the Epic line. Let me tell you, these clubs are hot off the face. 

In response to our review of the newest Epic line of drivers, I received multiple requests to do some research on the Big Bertha B21 driver. While I had heard of this club, I didn’t know much about it. But I was curious to learn more. 

So, I took to the streets and dove in head first with the Big Bertha B21. Let’s take a closer look at the findings.

Key Features

AI Flash Face design promotes faster ball speeds across the face for more distance, even on mishits.

Internal draw bias promotes straighter shots for players that slice.

Jailbreak Technology and T2C Triaxial Carbon Crown allow for faster clubhead speed and increased forgiveness.

Design and Technology

Callaway continues to push the envelope when it comes to driver technology and design. I never thought I’d see the day when AI was used in the design process. But sure enough, that’s what Callaway is doing. With that said, there’s plenty more tech to talk about in the B21.

In order to create a higher launch with less spin, Callaway has moved the CG farther forward and lower in the head. In testing, this has indeed reduced spin and increased launch angle – the equation for long, straight drives.

Internal draw bias has added weight in the heel of the club which helps players square the face through impact for straighter shots. 

The face is somewhat revolutionary as well. AI designed Flash Face SS21 is designed to promote faster ball speeds across the face for more distance.

Callaway’s patented Jailbreak Technology employs two vertical bars behind the face that connect the crown and sole. The extra reinforcement increases stability at impact and also works to promote faster ball speeds.

The T2C Triaxial Carbon Crown is much lighter than in previous models. This has allowed weight to be redistributed to other areas of the club where it’s more efficient.

Our Experience

I haven’t had the chance to hit the Big Bertha B21 personally (I tend to draw the ball too much, so this club doesn’t fit my swing), but a number of our readers have. Across the board, their feedback has been resoundingly positive.

Specifically, they’ve noted much straighter, longer tee shots thanks to the inherent draw bias. They also tout the solid feel and sound at impact, even on mishits.
