Pure full carbon shaft experience. Engage has been designed to offer the players a pure full carbon experience, starting from the taper, passing through the sound, and arriving at its surface finish. It was born with these objectives, and after years of research and development, starting from the already excellent Prime M and using BeCues experience in the composite fiber world, we managed to get what they wanted. The Engage shaft is made entirely of unidirectional carbon fiber, with several suitably sized and oriented layers coupled together to enhance as much as possible the positive characteristics of carbon in relation to the game of billiards.
