SRAM XG-1090 PowerDome-X 10sp Cassette



Sorry, this item is out of stock

  • Superlight PowerDome-X construction: middle 8 cogs are heat treated and CNC-machined from a single piece of 4130 CrMo steel, providing a harder and ultimately lighter product than titanium
  • Lightening ports in larger cog shelves mated with a spider-ported aluminum big cog and steel 11t 1st-position cog mirror the strength and weight savings borrowed from XX technology (CX: 12-27 range specifically designed or Cyclocross gearing)
  • X-Glide tooth profiling coupled with elastomer StealthRing spacers reduce vibration and drivetrain noise while providing super-fast shifts and loss-less power transfer
  • Fits 8-10sp SRAM/Shimano-spline freehub bodies for 10sp shifting/spacing
  • Includes anodized 7000-series aluminum lockring
