Callaway Great Big Bertha EPIC: The Technology Explained

By: Golfshake Editor | Wed 04 Jan 2017 | Comments

Golfshake's Owen Davies caught up with Alan Hocknell from Callaway's R&D department to talk through the new and innovative technology used within the Callaway Great Big Bertha EPIC Driver.

The Technology Explained: 

Jailbreak Technology has delivered greater ball speed and distance by changing the fundamentals of how the head and clubface act at impact. The key structural components of a metalwood – crown, sole and face – each bend, flex and rebound. Being connected, they influence each other’s dynamics, with this new technology creating a noticeably efficient relationship between these components to allow for increased speed across a larger area of the face.

Elsewhere, the titanium Exo-Cage has combined with crown sole panels made of triaxial carbon, which is an extremely light and strong composite material that been developed by Callaway. Nearly half of the head’s surface, 46%, consists of triaxial carbon, with the crown weighing just 9.7g and the sole a mere 5.8g. That’s the lightest crown ever in a Callaway Driver and of any currently on the market. Epic’s multi-material structure is incredibly light and strong, with exceptional MOI and a low CG that makes it easy to launch the ball high with low spin.

Adjustable Perimeter Weighting Technology (APW) features heavily in the EPIC’s increased shot-shape control comes from Callaway’s APW, which, compared to previous models, has a shorter track with a heavier sliding weight. The weight saving from the shorter track allows for this weight to be heavier (17 grams) and helps increase MOI as well as deliver a full 21 yards of shot-shape correction (a 22% increase compared to Great Big Bertha).

Also included is the Latest Speed Step Technology which means that head speed gets an additional boost from the latest version of Callaway’s Speed Step technology, which was originally developed in partnership with Boeing. Located on the crown, the Speed Step improves airflow to encourage more swing speed and distance without extra effort.
