PRO-PERFECTED PRECISION
ROG Gladius IV Ace
Designed for players who live by control, the ROG Gladius IV Ace gaming mouse combines a science-backed ergonomic shape with customizable weight, consistent click feel, next-gen ROG SpeedNova 8K Gen II wireless, and a high-precision sensor.
Backed by Science.
Tested with Pros.
Developed through extensive sports-science testing and iterative evaluations with esports players, the ergonomic shape of the ROG Gladius IV Ace helps reduce muscle strain while the hand grips, lifts, and moves the mouse during competitive play.
Customizable Weight and Center-Balanced Design
56-gram default weight with stackable modular weights for eight configurations
Weight tuning design positioned at the center of the mouse to ensure balance and consistent handling
Stackable Weight Combinations
The 3g, 5g, and 7g weights included with the ROG Gladius IV Ace provide seven different weight configurations: 56 g (default)
- - 56g (default)
- - 59g (+3g weight)
- - 61g (+5g weight)
- - 63g (+7g weight)
- - 64g (+3g, 5g weights)
- - 66g (+3g, 7g weights)
- - 68g (+5g, 7g weights)
- - 71g (+3g, 5g, 7g weights)
Precision-Matched Clicks
Each switch is sorted by click force before installation, with the left and right buttons matched using switches within the same force range. After assembly, every mouse is individually machine-tested as a complete unit to verify strict left- and right-click consistency within 5 gf, ensuring a closely matched actuation force between the two primary buttons.
ROG SpeedNova 8K Gen II Receiver
A large antenna and the placement of the desktop, the receiver helps strengthen wireless signal quality. By keeping the receiver closer to the mouse, players get a more stable connection for consistent performance.
The receiver detects surrounding RF conditions and indicates connection quality in real time. Players can adjust receiver placement to maintain a cleaner, more stable wireless signal.
Powered by an upgraded MCU, ROG SpeedNova 8K Gen II achieves 40% lower latency compared to the previous generation. Its larger antenna and new RF architecture with Active Dynamic Hopping scans the environment for optimal channels, helping reduce interference for more stable wireless performance in competitive play.
Dual LEDs provide quick visual feedback for RF status, battery level, and active profile. Players can personalize the indicators via Gear Link to surface the information they need most during play.
