Racket signed by Italian Sofia Cimatti, in the 2026 version, for advanced players who prefer a slightly thinner profile. It has a 3K carbon face, three-layer Soft Pro EVA core, 320 g (±5 g), 21 mm thickness, 50 cm and a 26 cm balance with balanced impact. The paint with microgranules helps with spin, and the elastomer vibration dampener on the face plus the double cap on the handle make the hit more comfortable.

How the RR Score was calculated

CriterionWeightScore
Specs65%64
Approval from players35%70

The RR Score is not yet a precise figure. It summarizes the data we have today (specs and reviews) and changes as more information comes in. A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy.

Buyer reviews

Average of the ratings given at each store, weighted by how many reviews each one has.

Store ratings may reflect the store experience (shipping, service), not only the racquet.
