Diadem Project Bublik 98 Racket
Series: Diadem
$269.95
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.

What players say
This is a recently released frame and most available player feedback comes from Diadem's own site reviews rather than established review outlets, so the sample is small. The handful of players who have posted reviews describe strong spin, comfortable feel, and power that's close to a Babolat Pure Aero 98 once lead weight is added.
Best for
- Players moving off a stiffer 98 sq in frame for more comfort
- Control players who still want strong spin access
- Players who like a feel between a crisp frame and a muted one
Pros
- Strong, consistent spin generation noted by multiple reviewers
- Comfortable/arm-friendly compared to the 2023 Babolat Pure Aero 98, which one reviewer said caused wrist pain
- Feel described as dampened but not dead - sits between a crisp frame and a muted one like the 2026 Yonex VCORE 98
- Solid power for a control-oriented 98 sq in, 16x20 frame
Cons
- Power trails the Babolat Pure Aero 98 out of the box, according to one long-term tester, unless weight is added at 3 and 9
- Independent, established-outlet reviews (YouTube, forums) are scarce so far - feedback is mostly limited to a few customer reviews on Diadem's own site

Comfortable racquet compares to 2023 Aero 98 which was giving me wrist pain. Spin generation is good and power also, a little less than Aero 98 but adding some weights on 6 & 9 makes them very similar

Great racquet! Definitely a racquet I'd be willing to use along with my 23 Aero98's

Definitely a lot of spin generated with this racquet and also not shabby in the power. Best racquet in the Diadem line by a mile!
