STONE 110BCD Spider Adapter for 1X Chainring – SRAM 3/8-Bolt, ROTOR KAPIC/ALDHU/VEGAS, Easton EC90 & XXE GP3 Direct Mount Cranks

The STONE 110BCD spider adapter is a precision component for riders who want to run a single chainring on a direct mount crankset. It bridges the gap between modern crank interfaces and standard 110BCD chainrings, in both 4-arm and 5-arm versions.

This spider adapter converts compatible direct mount cranksets to a 1X single chainring setup, delivering a precise fit and a cleaner, simpler drivetrain.

For 1X single chainring setups only. Not compatible with double chainring / 2X setups.

Main Compatibility

  • Works with 110BCD single chainrings
  • Works with 1X narrow-wide chainrings
  • Works with fixed gear / fixie 110BCD chainrings
  • Not for double chainring setups
  • Not for 2X drivetrain setups

Supported Crank Interfaces

Several spider models are available. Please choose the correct one according to your crank interface.
