Welcome to Project Bublik

Project Bublik is the story of an ongoing development process between Alexander Bublik and Diadem. It's a working snapshot of the specs, feel, and construction being refined toward his eventual signature frame. With dozens of prototypes and thousands of design decisions, Project Bublik is a work-in-progress that players around the world get to participate in. 

Most signature rackets are launched as finished products. We did the opposite. Project Bublik is a checkpoint along the way rather than a final conclusion.

Diadem and Bublik are building his frame the way he plays: entertaining, unconventional, and with a refusal to settle. Project Bublik captures that process mid-stride with current specs, current tuning, current feel. Never stagnant, always moving.

"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."
