Corsair is about to enter the ultralight arms race with some serious firepower. According to a leak from Australian retailer JB Hi-Fi, the upcoming Corsair Sabre V2 Pro Ultralight mouse is dropping soon and it’s looking like a direct swing at Logitech’s crown.

Corsair Sabre V2 Pro drops weight, amps up performance

The headline spec is wild enough: just 36 grams. That puts it well below rivals like the Logitech G Pro X Superlight 2, which weighs 60 g. Yet somehow, Corsair isn’t cutting corners. The Sabre V2 Pro Ultralight will include the same Marksman S sensor found in Corsair’s top-tier mice, with a sensitivity ceiling of 33,000 DPI and a polling rate of up to 8,000 Hz.

For anyone chasing precision and speed, this mouse looks built to deliver.

Symmetrical shape marks a big design pivot

Corsair is ditching the old asymmetrical shell and going with a symmetrical layout and mid-hump design. That makes the Corsair Sabre V2 Pro better suited for a wider range of grip styles and opens up partial usability for left-handed players. Just don’t expect mirrored side buttons; those are still right-hand focused.

Key specs leaked for the Corsair Sabre V2 Pro Ultralight:

• Weight: 36 g
• Sensor: Marksman S, up to 33,000 DPI
• Polling rate: Up to 8,000 Hz
• Battery life: 70 hours at 1,000 Hz
• Wireless: 2.4 GHz only
• Dimensions: 119.5 × 62.5 × 38.21 mm
• Optional grip tape and swappable skates included

Web-based driver and mid-range price add appeal

Corsair’s move to a web driver for customization is a smart play, especially for those tired of bloated software. It echoes what we liked in recent Keychron mice: light, fast, and no installation needed. The mouse is expected to launch around AUD169, which roughly translates to $100–$112 USD. That makes it competitively priced against the Logitech G Pro X without chasing the ultra-premium tier.

If the performance holds up in real-world testing, the Corsair Sabre V2 Pro could end up being 2025’s dark horse in the ultralight wireless mouse game. All signs point to a mouse that doesn’t just match the competition, it undercuts them, one gram at a time.
