A 4-bolt 107 BCD chainring that bolts straight onto SRAM XPLR and Quarq (Force/Rival) gravel cranks and power meters, adding range without swapping the whole crank.

Highlights

  • 4-bolt, 107 BCD — fits SRAM XPLR cranks and Quarq Force/Rival power meter cranks
  • 7075-T6 aluminium
  • Cross-compatible with SRAM and Shimano 11- and 12-speed drivetrains
