  • Alloy 5 beam spider carrier with 3 alloy, 5 titanium and 4 chromoly sprockets make this a lightweight, stiff and durable 12-speed micro spline MTB cassette

  • 10-45t wide ratio gearing allows a more efficient use of energy through finer cadence control in ever changing trail conditions
  • sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity
  • sprockets use hard anodising and nickel-plated finish for added durability and resistance to corrosion
  • for use only with micro spline freehub bodies
  • alloy cassette lockring
  • for use with Shimano 12-speed sil-tec chains
  • average weight 357g
