Callaway Big Bertha B21 Driver Review

50 Words or Less

Built to combat the all too common slice, the Callaway Big Bertha B21 driver delivers straight distance.  Low spin and excellent forgiveness with distinctive looks.

Introduction

Big Bertha is one of the great names in golf equipment.  Launched in 1991, the all stainless steel club head ushered in the new age of metal woods.  Over the years, the size has grown substantially and the materials have become more exotic, but the soul of Big Bertha remains focused on making golf more enjoyable.  Now, even with their stellar MAVRIK driver lineup [check out all our reviews HERE], Callaway adds the Big Bertha B21 giving golfers another option for matching their needs.  The comfort of a familiar name and the hope ‘21’ brings – thanks Callaway.

Looks

Exposed carbon fiber weave isn’t anything new, but Callaway hit it out of the park with the blue of the Big Bertha B21.  The triangular shaped head is reminiscent of the Big Bertha Fusion, but with better balance and overall visual appeal.  The chevron aim point and red pinstriping really pop and complete a powerful look at address.  Most notable is the lack of offset, a feature I expected to find in a draw biased driver.

The face of the B21 is tall and inviting with an almost square appearance.  The sole is somewhat busy with numerous recessed areas and finishes.  The deep metallic blue does coordinate well with the crown as do the red accents.   Overall the Big Bertha B21 has a distinctive look – both in the bag and in your hands.

Sound & Feel

The Big Bertha B21 driver produces a staccato metallic crack that’s a medium plus in volume.  The sound is markedly consistent across the face and although distinctive, doesn’t draw attention.

With the stock Callaway RCH 65 regular shaft, the club felt very balanced throughout the swing.  At impact the head felt stable and invoked the word “POW” as if Batman had landed a punch as the ball left the tee.  To my hands, feedback was marginal as would be expected from a large, forgiving face.

Performance

My normal golf swing produces a slight draw which typically gets exaggerated by draw biased clubs, so I was a bit perplexed when that didn’t happen with the Big Bertha B21 driver.  Ball flight was straight and stayed right of center.  Opening up my stance a bit for a fade, once again the ball flew straight but held left of center.  With a little more tinkering I was hitting drives straight down the fairway.  If you’ve been compensating for a slice or a push by aiming down the left side, you’re going to enjoy aiming at your actual target with the B21.

As I looked over the launch monitor data collected at Club Champion, smash factor really stood out.  Even while working out how to hit the driver, the lowest smash was 1.49.  Matt Saternus and I both marveled at the Flash Face SS20 utilized in the MAVRIK lineup, and the Flash Face SS21 version on the Big Bertha B21 is equally impressive.  To assist in the delivery of strong ball speed and forgiveness, Callaway also implemented their proven Jailbreak and a T2C Carbon Crown technologies.

Along with internal weighting, Callaway utilized low spin for the slice busting, straight ball flight design of the Big Bertha B21 driver.  The low and forward CG definitely produced low spin throughout my testing.  My trajectory was a bit low with the 10.5° loft which is likely attributable to the combination of low spin and shaft dynamics.    The B21 driver does have an adjustable hosel for fine tuning, but don’t be afraid to try the 9° or 12.5° models.

Conclusion

It took some time to figure this driver out, but in the end it seemed that Callaway had indeed developed a “new formula” for straightening out tee shots.  Comfortable and confident with the B21, I ratcheted up my swing to 87 mph and cranked out a 240 yard beauty – really solid for my game.  The Big Bertha B21 driver adds another great option to the Callaway driver arsenal.

    Can I please have one? I can’t afford one in today’s market and I love this club very much.
    Your friend Paul Rynearson

  2. I am 67 years old and play with my 30 year old son two or three weekends monthly.. I currently use a Taylormade M2D and most times hit it straight off the tee. But when I am trying to get farther down the fairway It takes off okay then I see the flight path go right. Not that Im looking to spend $500 dollars, but will this club help.

    • That’s great that you get to play with your son that frequently Robert. The only way to find the answer is for you to hit the club. If you work with a qualified fitter, you also may find a shaft change in your current driver helps achieve the ball flight you desire.

    just bought the B21 to try to cure my chronic fade. i was skeptical, after lessons from two pros and various tinkering with my stance didn’t help. so-good news. did not see the draw on my drives but-surprise!-my drives are going straight. very satisfied.

  4. Thanks for another great review and for the testing of this club at the lower swing speed. So many reviews on equipment are done by the 100+ mph swing speed player. We slower speed players sometimes feel neglected and this review benefits us. I will be looking forward to testing this club.

  5. I purchased this driver and fairway wood. Love it. I am now hitting 250+ yard drives and a few 290 yard drives. Very easy to hit. Excellent feel. Longer than my previous Callaway. I am very happy with my purchase. These woods along with the Epic Forged irons allows me to keep up with the long hitters and go after some par fives in two.

  6. Hi Matt,
    Thank you for your excellent,clear helpful review of the new B 21 driver. I appreciate the 82 mph clubhead speed instead
    of a pro smashing the ball at a speed far beyond the capabilities of the golfer likely to buy this club.
    It seems to be a great club for older handicap 20 + players.
    Unfortunately this quality club has a price to match the high performance it can produce for a reasonable golfer.
    Renewed thanks for an interesting review.

    Hi Matt,
    Thank you for an excellent review.
    For a 77 year old, who hits a Ping G 400 SFT 150 to 170 yards, usually in the fairway with a fade with a soft regular shaft, 13* loft would you recommend a Callaway B 21 or a Ping 410 SFT.?
    I intend to get fitted but would appreciate your excellent unbiased advice than completely rely on a fitter/salesman
    who is keen to make a good profit.
    I regularly watch plugged in golf for honest, valuable ,helpful ,. advice.
    Many thanks, Alan Goudie

      Thanks for the kind words Alan. In doing research you are way ahead of the average golfer and ready to look past any slick sales efforts. The key as you know is to see which club performs best for you. You’ve narrowed it down to two great options. The Ping will likely feel familiar so try to sort out if the Callaway feels different/good or different/bad. Let us know what you decide on.

    Big Bertha ! What can I say . 8 degree would be nice . 5 degree even better . They are not on the list . I prefer to make the club ” talk ” it’s my time to listen . Hopefully B21 lives up to its ancestors ?

    My driver speed is also around 82/83. Trying a demo and sure enough using a 12.5 set to 11.5° I was seeing around 190 carry (guessing from landing spots on my home course) and totaled around 227 on a couple. Nice to see a reviewer with a swing speed I can relate to.
