2024 Testing Initiative

THE BOARD IS BACK – For the 20th Anniversary of Diamana™, the vintage surfboard so closely associated with the brand makes a triumphant return on the 6th generation WB model. Built on an extraordinarily popular and tour-proven platform, WB brings classic low-low performance and the legendary stability and control you’ve come to expect after two decades.

YOU'RE INVITED TO PARTICIPATE – This Spring we're asking golf pros nationwide to participate in a limited run Diamana Testing Initiative to gather feedback on the latest Diamana shaft and better understand their needs in their fitting process. We will choose a select group of pros from the first 50 registrants to receive a tipped/gripped shaft in the weight/flex of their choice. To be considered for the program, please use the form below to register.

THE SHAFT THAT SET THE STANDARD – Diamana WB is designed with all the traditional branding that made Diamana™ so beloved, including flowers in the handle section, a surfboard behind the Diamana logo, and return to the original 53/63/73/83 weight class designations. But rest assured, the only thing throwback about Diamana™ WB is its appearance. Indeed, super high-modulus 80-ton Dialead Pitch Fiber is used in the butt section to deliver maximum stability and increased energy transfer and high modulus 46-ton fiber is used in the shaft’s angle plies to reduce torque without increasing weight for improved control and stability. Carbon fiber orientation at the tip section is optimized to further lower torque.
