The Diadem Project Bublik 100 Tennis Racket 2026 is part of the ongoing collaboration between Diadem and Alexander Bublik as they work toward his eventual signature frame. Built through dozens of prototypes and thousands of individual design decisions, the Project Bublik range makes that development process available to players around the world — each model tuned to a different player profile, all shaped by the same partnership and philosophy.
The Project Bublik 100 is designed for a broader range of players than the pro-stock 98. Where the 98 captures Bublik’s own competitive specifications most directly, the 100 takes the same collaboration and applies it to a frame that suits players who want the Project Bublik character — fast, unconventional, power-forward — in a more accessible weight and flex. The result is a racket that carries the identity of the Bublik x Diadem partnership without being a replica of his tour setup.
“Tennis, for me, has always been about doing things my way. So when I started working with Diadem to build my perfect racket, I wanted the same thing: something built exactly for how I play, with no compromises. Project Bublik is the first step of that journey. It’s a frame we’ve developed together, tuned to my specs, my feel, my game. It’s not finished yet. We’re still refining, still pushing, still chasing perfection. But I wanted you to be part of that process.”
— Alexander Bublik
The 100 in² head and open 16×19 string pattern deliver an accessible combination of easy power, ball bite, and spin potential. At 300g with a 4-point head-light balance at 330mm, it swings quickly on groundstrokes and remains composed at the net. The 64 stiffness rating keeps the response comfortable through contact, providing a forgiving flex that cushions off-centre hits rather than punishing them. High elastic carbon construction and an airfoil frame shape increase racquet head speed through the swing arc, converting effort into pace efficiently without demanding a technically advanced swing.
Choose the 100 if you want the same open pattern and head size as the Team 100 but with more mass and weight behind every shot.
