Cassette XG-1190.FEATURES:-Sometimes all you need is a fresh coat of paint.With revised graphics to match SRAM RED® eTap® components, the PowerdomeX™ is still the most advanced cassette ever made.It´s super light, silent, and delivers an undeniable performance advantage.The nine cogs in the cog cluster are machined from a single block of high grade tool steel, increasing stiffness while weighing even less than a titanium cassette.Between each cog is a StealthRing™ elastomer to reduce vibration and noise.Cutouts on the rear cog further reduce weight and add stiffness.It´s the final piece in the drivetrain puzzle, and paired with a SRAM RED® rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear.- Speed (CS):11s.- Gearing:11-25t, 11-26t, 11-28t, 11-30t, 11-32t.- Cog finish (Cassette):Silver.- Technology (Cassette):XG.- Cog sizes:.- 11-25t:11,12,13,14,15,16,17,19,21,23,25,.- 11-26t:11,12,13,14,15,16,17,19,21,23,26,.- 11-28t:11,12,13,14,15,16,17,19,22,25,28,.- 11-30t:11,12,13,14,15,17,19,21,24,27,30,.- 11-32t:11,12,13,14,15,17,19,22,25,28,32.SPECIFICATIONS:-.
