GSI Interlock Base Module

The GSI Interlock Base Module is the core of the modular Interlock wheel system, sold without a rim so you can build the wheel you want around it. The module carries the controls: 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 that include a 4 + 15 + 4 telemetry strip.

You decide how far to take it. Order it with no paddles or with 2 or 4 paddles in aluminum or carbon fiber, and add the LED Matrix for gear, flag and alert animations now or at any time later. Then mount a GSI GT 300, GT 320, Oval 320 or Ultra 300 mm rim, or a third-party rim with a 70 mm PCD that clears the controls.

A USB-C port beneath the hub supports passthrough quick releases, and the module switches power automatically between that and the included coiled cable. It runs GSI’s simOS firmware on Windows PC.
