GSI Interlock Base Module + Rim

The GSI Interlock Base Module + Rim is the simplest way into GSI’s modular Interlock system: you get the Interlock core together with a GSI rim in one order. Pick Blackout or Prime, then choose a GT 300 mm, GT 320 mm or Oval 320 mm rim with a perforated or suede grip, each built on a rigid alloy core.

The core carries 12 RGB push buttons at 500 gf, two seven-way switches, two thumb encoders and two 5-way rotary encoders at 6.5 N·cm, plus 90 addressable RGB LEDs with a 4 + 15 + 4 telemetry strip. Configure it with no paddles or with 2 or 4 paddles in aluminum or carbon fiber, and choose whether to add the LED Matrix for gear, flag and alert animations.

The Interlock parts are made to work as one system, so you can add pieces or change rims as your setup grows. The wheel runs GSI’s simOS firmware and connects to a Windows PC through the included coiled cable or a USB-C passthrough quick release.
