Players at all levels are realizing the benefits of a dedicated fitting. Diamana TB-Series shafts are designed explicitly to maximize this process. Through a new Consistent Feel Design, Diamana TB-Series feature minimal variance in butt OD, weight and balance point through the entire range – from 40R2 to 80TX. This minimizes any change in feel as a player shifts among options, allowing a fitter to focus on finding the ideal weight/flex pairing for maximum performance. Constructed using a new dual-phase Mitsubishi Chemical [#371 resin system] that produces a carbon-rich structure that is both universally stronger and more responsive. Who it’s best for? Diamana TB-Series is ideal for club fitters working with a broad range of players who could benefit from smooth profile shaft, fit with even greater precision. ******* This shaft is custom assembled and will be ready to install into your driver head right out of the box.
