Our scores, updated 9 July 2026 · How we score
Score by score
How we score →The green bar wins the round. The Electra takes 1 of the six, the Rialto takes control and sweet spot and comfort and handling, and value is level.
Feel is read from the core and the face until hardness is measured.
What is different
Face, weight and price change between them; the rest is the same. Pick one to look closer.
12K packs 12,000 carbon filaments into each thread against 3,000: a stiffer face that answers sooner on volleys. The Rialto's 3K is a little softer and gives you more time when you are late.
Edge: the Electra, for precision
* The feel starts from the core's rated hardness (estimated from the core material where there is no rating), then the face: carbon 12K and up is firmer, fibreglass softer.
The Electra is about 340 g lighter: quicker to the ball at the net. The Rialto puts a little more weight behind a smash.
Edge: the Electra, for quick hands
The balance point is not listed for both.
No edge either way
* Drawn to scale: a 455 mm racket in its shape's outline (traced from a real racket of that shape), with the balance point the shops list marked on it. Real rackets vary by a few millimetres.
Only the Electra is at PadelProShop right now, at €179.
