Stages Power R Ultegra R8000 Single Drive Side With Chainrings

The new gen 3 single-sided Stages Power R meter is built on the drive-side Shimano Ultegra R8000 crank arm and is compatible with all Shimano Hollowtech II road drivetrains.  The newest version includes chainrings of your choice. 

Single drive-side power meter increases frame compatibility or upgrades an existing Stages Power L meter to Stages Power LR.  Stages Power R offers increased compatibility with direct mount brakes and frames that lack adequate chainstay clearance, as well as the ability to upgrade existing Stages Power L power meters to Stages Power LR bi-lateral (dual) meter systems.
