Diadem Project Bublik 98 Tennis Racket 2026 (Unstrung) | Alexander Bublik's Racket
The Diadem Project Bublik 98 Tennis Racket 2026 represents something genuinely different in the world of performance tennis equipment. Rather than arriving as a polished, concluded signature frame, it is a live document, a frame that captures exactly where Alexander Bublik and Diadem stand in their collaboration at this moment in time. Built through dozens of prototypes and thousands of individual design decisions, the Project Bublik 98 reflects current specs, current tuning, and current feel. It is not the endpoint. It is the process, made playable.
The partnership between Bublik and Diadem is built on the same qualities that define his game: entertainment, refusal to conform, and an unwillingness to accept anything less than what he actually needs on court. Rather than releasing a signature racket as a finished statement, Diadem and Bublik chose to open up the development journey itself — sharing each meaningful checkpoint with players around the world who want to be part of it. Project Bublik moves forward the way Bublik plays: always unconventional, never standing still.
“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
On a technical level, the Project Bublik 98 is the most control-oriented frame in the range. The 98 in² head and tight 16×20 string pattern work together to produce a precise, stable response through contact, with a playing character that rewards players who want to dictate the ball rather than rely on the frame to do the work. At 302g with a 6-point head-light balance at 323mm, it sits in the heavier, more head-light end of the Project Bublik family — the model best suited to players who generate their own pace and want the maximum feel and directional control in return. The 21.5–23.5–22mm beam and stiffness rating of 67 further reinforce its precision-first character, offering stability through the swing arc without sacrificing the feedback advanced players rely on.
Choose the 98 if you want the smallest head, the tightest string pattern, and the most head-light balance of the Project Bublik range — and a frame built for players who want to create the game entirely on their own terms.
