The Interlock Ultra is the flagship of the system, featuring a unique rim design with the LED Matrix seamlessly built in. It delivers a clean, integrated experience right out of the box — distinct within the Interlock lineup and built to stand on its own. START ANYWHERE, GO ANYWHERE No matter where you begin, every interlock can evolve into any other. Go fully custom with a compatible third party rim. POWER-LINK QR READY Since the beginning, we’ve pushed boundaries to create the ultimate sim racing products. The Interlock sets a new foundation for the future, built around our latest electronics and modular design.It’s already prepared for our upcoming GSI Powerlink-QR, our next-generation passthrough QR that provides both power and data, with a conventionally placed USB-C port beneath the hub for effortless connectivity. The Interlock is ready not only for the GSI Powerlink-QR but also for any passthrough QR that uses a USB-C connection—no need to open the wheel to adapt. It also features dynamic power switching, intelligently recognizing whether it’s connected through the passthrough QR or the coiled cable—giving you seamless flexibility and complete freedom in how you connect. simOS Architecture GSI wheels run on simOS, our custom firmware optimized specifically for sim racing. It includes features like predictive algorithms to optimize responsiveness and intelligently manage power and data, as well as a suite of useful features that integrate directly with the simOS app. What's Included: Interlock Ultra GSI "Spec 3" Coiled USB Cable Compatibility: Wheelbases (Windows PC Only)SimucubeVRS DirectForce ProFanatec DD Bases(via SRM Fanatec Emulator Hub or Fanatec Podium Hub)Most 8nm+ wheelbasesAsetek (via Asetek Invicta QR)Moza (via Moza QR)Simagic (via Simagic QR) Specifications: INPUTSMappable Inputs: 42Push Buttons: 12 (500gf)Thumb Encoders: 25 Way Encoders: 2 (6.5n.cm)7-Way Switches: 2Available N52 Shifters: YesAvailable HSE Clutches: YesTop Paddles: NoILLUMINATIONDisplay: LED MatrixAddressable RGB LEDs: 90RGB Telemetry Strip: 4+15+4RGB Buttons: YesRGB 5-Way Encoders: YesCONSTRUCTIONFront Plate: Matte Brushed AluminumHandle Material: Perforated Faux LeatherAluminum Unibody: YesScratch-Resistant Polycarbonate Buttons: YesCUSTOMIZATIONLabel Text + Colors: NoButton Layout: NoRotary Knobs: YesMEASUREMENTSDiameter: 300mmBolt Pattern (PCD): 70mm (6 x M5) Recommended ConnectionGSI Coiled Cable → Powered USB Hub → PCUSB extension cables are not recommended.
