Big Bertha B21 Driver
Distance Any Way You Swing It
You could be hitting the ball farther, and that's why we're bringing out the new Big Bertha B21. It's a new formula for distance, built to take the big miss out of your game and invite you back to the fairway. Tool NOT included.

Features &
Benefits
- Unlock Your Inner Distance
If you want to hit the ball farther, you have to hit it straighter. And to help eliminate your slice or big miss, we've created our first high launch driver with an ultra-low forward CG for low spin. It's a new formula for distance to give you a more consistent ball flight, and more tee shots that find the fairway. - Fast Ball Speeds From Our A.I. Designed Flash Face SS21
We've advanced our A.I. designed Flash Face to promote fast ball speeds across a more expansive area. So you'll still hit it a long way, even when you miss the center of the face. - Easy To Hit From Bertha Shaping And Added Draw Bias
Built to improve your launch angles, and stop your slice. The large Big Bertha head is specifically engineered with internal draw bias weighting for a straighter, longer ball flight. - Super Strength Materials For High, Consistent Ball Speeds
Promotes optimal speed, forgiveness and spin characteristics from a face architecture that's extremely strong and lighter than traditional titanium. - Jailbreak + T2C Triaxial Carbon Crown For Ball Speed and Unconventional Forgiveness
Two internal Jailbreak bars connect the sole and crown to promote fast ball speeds, and the significantly lighter carbon crown allows us to redistribute weight for higher MOI.

B21 is Number 1
November 14, 2021
Without a doubt, this is the best driver I have had in the last decade. Right from the get-go, I gained 15 yards per drive and once I got to grips with it probably longer. Thoroughly recommend this club to anyone trying to improve the driving part of their game.
Also big shout out for Rock Bottom. They promised a date it would arrive and so it did. Also the best price I could find and I searched around a lot. Cheers!!
