What is it?

TE engineers replaced steel from the crown with a 100% carbon fiber crown in this hybrid design. 


What does it do?

The use of an all-Carbon crown saves considerable weight.  This weight savings is then moved to the ideal location to help with creating the optimal CG location.  The C721 hybrid has a low-rearward CG position that produces an extremely high M.O.I. to increase stability at impact. 


This is the first Exotics hybrid to ever feature Carbon Fiber on the crown.



What is it?

Diamond Face 2.0 is made up of diamond shapes of variable thickness behind the face.  There are 41 total diamond shapes featured on Diamond Face 2.0, comprising seven different thicknesses in an interweaving pattern. This compares to the three different thicknesses used on the initial Diamond Face design.


Face thickness of Diamond Face 2.0 at the extreme perimeters of the face is also reduced by 20%. 


What does it do?

The mini trampolines that make-up Diamond Face 2.0 create faster ball speeds and an expanded sweet spot.  


The increase in Diamond Face 2.0 coverage to the extreme heel and toe dramatically increases ball speed and forgiveness on off-center hits.




What is it?
A new lighter and stronger 450-Hyper-Steel Face construction is used on the 721 hybrid.



What does it do?

Our new face creates amazing feel and a powerful rebound for more ball speed. 



What is it?

A 5-gram adjustable back weight is located at the extreme rear of the clubhead.


What does it do?

The position of the backweight helps deliver an optimally located CG, maximizing M.O.I. and aiding extreme stability and resistance to twisting at impact.  


Installation of different weights also allows dialing in of required swing weights at custom lengths.


Additional weights available in 10 grams and 15 grams.



What is it?

Sound Diffusion Panels are strategically-placed panels located inside the club.


What do they do?

These Panels vastly improve the acoustic properties of the driver by directing and diffusing sound waves within the club head on impact.  This enhances the richness of the sound produced. 


Working in concert with the Sound Diffusion Panels, inherent design aspects of Ridgeback and the wrap around Carbon Wings all work together to orchestrate the 721 driver’s industry-leading sound and feel.


The shaft make-up in the 721 Series is unique to the industry. We tested an extensive range of market-leading shafts with our Tour Edge Development robot to find the the best-performing custom shafts for every swing speed.
