    Key features

    Plateau STONEDW Hollow Easton Cinch, Noir, vue de face

    Sold as a 4 mm, the chainring is offset 4.4 mm inboard.

    Plateau STONEDW Hollow Easton Cinch, Noir, monté sur une manivelle Easton

    The 7075-T651 plate stays flat after machining, and interface parallelism is held to 0.02 mm. That keeps runout down once the chainring is tightened on the crank.

    Plateau STONEDW Hollow Easton Cinch, Noir, monté sur un vélo gravel

    The hollow design weighs 95.1 g in 38T and 174 g in 58T. Stone recommends 40 to 44 teeth for gravel, 46 to 50 for everyday road riding.

    Description

    The STONEDW Hollow Easton Cinch is a hollow single chainring for road and gravel, for Easton EC90 and EC90 SL Cinch cranks or any crank with the same interface. It needs a SRAM AXS Flattop or T-Type chain and mounts directly, with no power meter spider.

    It runs true because it starts from an 8 mm plate of 7075-T651, a temper that reduces internal stresses: the aluminium stays flat after machining. STONEDW checks interface parallelism to 0.02 mm, to limit runout.

    Its actual offset is 4.4 mm, sold as a 4 mm. Every millimetre of offset brings the teeth closer to the frame: on the same crank, they sit 0.9 mm closer than on the Aero Easton Cinch at 3.5 mm. The chain stays straighter on the large sprockets. Not for MTB.

    STONEDW puts it on the test bench, 50,000 cycles at 1,500 N at 45°. MAAKE offers it for a hollow single chainring that keeps the Easton crank.
