Dual Optimum System – Frame profiles are normally designed around stability, aerodynamics or balance of both. The Dual Optimum System is half stability and half aerodynamic. The two sides of the frame use different profiles, rather than one profile trying to do both jobs.
Stability – On the orange side the racket uses a box shape frame to resist torsion and twist for more power transfer and precision.
Aerodynamic – The green side uses an aerodynamic profile with a Nickel-Titanium Fibre running around the crest for strength and durability.
Nanometric DR – Nanometric improves the bonding strength between carbon fibres allowing thinner carbon structures to have the same strength as thicker ones that dont use nanometric. Nanometric DR is used the the head of the racket in the box section to provide strength and stability around the head.
Solid Feel Core – A system to reduce the vibration through the racket for comfort and also provides a more robust feel to the racket.
Control Support Cap is a wider top cap to allow a higher control at the very top of the grip.
Super Slim Long Shaft – A thinned shaft for improved aerodynamics allowing a faster swing.
