RIDGEBACK TECHNOLOGY
What is it?
Ridgeback is a power producer. TE engineers created a titanium spine running from the center of the face through the crown and wrapping around the head to connect with the titanium sole plate.
What does it do?
This titanium spine within the carbon crown acts as a brace to produce more power on center hits. Bracing the center of the face also allows design of greater face flex in the heel and toe areas meaning off-center hits achieve greater power.
Ridgeback also creates superior feel at impact. The extra rigidity created by the brace through the crown produces a much stronger feel at impact when compared to a full carbon crown and results in a crisper and brighter feel at impact.
DUAL CARBON WINGS
What are they?
TE engineers replaced titanium from the crown and sole by creating wrap-around Carbon Wings.
What do they do?
The use of Dual Carbon wings saves considerable weight.
This weight savings is then moved to the ideal location to help with creating optimal CG location. The C721 driver has a low-rearward CG position that produces an extremely high M.O.I. to increase stability at impact.
The C721 Driver employs 19% more Carbon Fiber than any previous Exotics driver and the CG was lowered by 13% to improve launch characteristics.
DIAMOND FACE 2.0
What is it?
Diamond Face 2.0 is made up of diamond shapes of variable face thickness behind the face. There are 43 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 and of the driver dramatically increases ball speed and forgiveness on off-center hits.
ADJUSTABLE REAR BACKWEIGHT
What is it?
A 10-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 swingweight at custom driver lengths.
Additional weights available in 5 grams, 15 grams and 18 grams.
SOUND DIFFUSION PANELS
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.
ADJUSTABLE HOSEL
What is it?
The adjustable hosel allows golfers to adjust the loft +/- 2 degrees and lie angle through a range of 3 degrees.
What does it do?
With three lofts being offered (9.5°, 10.5°, and 12°) the 721 delivers a loft range of 7.5° to 14°, while various alternate settings afford lie angles from 59 degrees to 62 degrees.
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.
