Bryson testing prototype Cobra RadSpeed driver at Augusta National



The ever-testing, ever-questing Bryson DeChambeau is bringing his tireless pursuit of the perfect driver to Augusta National as he prepares for the 2021 Masters Tournament with a prototype Cobra RadSpeed driver in the bag.

With the rumblings of a new driver being put into play echoing among the Georga Pines, and a new driver head spotted on the USGA conforming list, we reached out to Cobra to get the inside information on the new driver being put into play by Bryson.

Here’s what Cobra Tour Manager Ben Schomin and VP of R&D Tom Olsavsky had to say.

GolfWRX: There is lots of talk about a new RadSpeed driver head being put into play this week by Bryson. What can you tell us about the new head that has been specifically tweaked for his high speeds?

Tom Olsavsky: The big thing here is speed and Bryson has a lot of it. To help build a driver specifically tuned for his dynamics, we removed the adjustable weights to save mass from the housings and have focused on internal changes to help him reduce miss-hit variance.

The other thing we did was increase the face thickness of his drivers to prolong durability. Bryson hits a lot of golf balls and with the amount that he hits both in standard practice and his speed training sessions, we wanted to help eliminate any durability concerns. We also suggest that he rotates the heads during sessions—and the adjustability in the hosel makes that easier to do.

Now speaking of the face, we specifically removed the Infinity Face on this new head, because it allows us to change the face radii easier and reduce the toe radius to help with his toe misses.

GolfWRX: Bryson really is unique as far as players you work with, isn’t he? 

Ben Schomin: Bryson hitting a 5-degree driver at 200+ mph ball speed certainly presents some different ball/club dynamics than we typically design for, so we’ve had to rethink some of our approaches. This head is our latest iteration to find something that works best for Bryson at extremely high speeds.

Tom Olsavsky: It’s basic physics: higher speed off-center hits result in greater variability due to the greater forces involved. Much of what we are seeing as far as misses are concerned seems to be due to club/ball friction at the interface between the two surfaces, which is very close to some instabilities in the contact physics. We are doing everything we can from an engineering perspective to keep the ball online more often.

    Can’t wait for him to drive it 11000 yards!

    No body noticing the acne on his face. It’s all over

    I’m starting to love Bryson. He’s clarifying the argument on why the USGA and R&A need to act on equipment regulations like never before.

    “Sorry, Mr. Ross” should go down in history as the moment that golf’s ruling bodies were officially put on notice, more than a decade after they admitted that they were on notice.

      I disagree…

      Should the USGA outlaw nutrition and training? The only thing that has changed in the last 20 years is training, launch monitors and agronomy.

      CoR/CT have been in place for nearly 20 years, ball speed has been limited too… athletes change. Should the NBA raise the hoop to 10 ft? Should the football field be lengthened?

    In short, they built a long drive head. It’s probably the same head Kyle Berkshire is hitting since he moved on over to Cobra from Callaway to join his buddy Bryson. Callaway pretty much had the same club in his hands and has mad them for years. XR ‘16 LD 5, Epic Flash LD 5, and this year an Epic Speed LD 5. They come with a special adjustable sleeve that has a special -2/-1/+1 deg loft option instead of the normal -1/+1+2 sleeve

      I have the XR 16 LD and noticed that it is much more durable than standard retail drivers and I have been hitting mine for 5 years now with caving in the face. I hear that the face is thicker and there may be some validity to that as any wood that I hit for that long of a period of time will fail. Cobra will definitely be putting out some quality woods if they are to stand up to the beating that Bryson and Berkshire will put on them.
