The Development Process

Built in the open

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.

In his words

Doing things my way.

“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.”
