Product

ShiftMate

Drivetrain component adapter

The ShiftMate is a CNC-machined interface device designed to resolve compatibility issues between different bicycle drivetrain components. It acts as a ratio-changing pulley that adjusts the cable pull to match varying component requirements, enabling the smooth integration of parts from different manufacturers, be it Shimano, SRAM, or Campagnolo. This makes it possible to mix and match components that would otherwise be incompatible.

  • Compatibility with various drivetrain systems
  • Durable construction with sealed ball bearings
  • Nickel plating for reduced friction and corrosion resistance
