Easton put its shifting rings through seven rounds of revisions, with lab testing and race testing alongside Silber Pro Cycling. Heavily machined for low weight and good stiffness, they shift cleanly thanks to optimised shift ramps and pins.

Highlights

  • 11-speed Shimano and SRAM compatible
  • Removable CINCH spider, 45mm chainline
  • Optimised shift ramps and pins
  • 50/34T, 52/36T or 53/39T

Built on CINCH
