The SRAM XG-1090 cassette RED® Powerdome X™ delivers an undeniable performance advantage. The eight cogs in the middle are machined from a single block of high grade tool steel, increasing stiffness while weighing even less than a titanium cassette. Between each cog in the block is a Stealth Ring™ elastomer to reduce vibration & noise. Cutouts on the rear cog further reduce weight & add stiffness.

Features: Hollow steel dome makes for a stiff & lightweight gear cluster. Heat-treated, high-grade tool steel provide superlative durability & a beautiful finish Stealth Ring™ elastomers & advanced tooth profiles eliminate vibration & noise for a smooth, silent ride Aluminum cog: lighter, stiffer, stronger due to the choice of design, material & production process Specifcations: Technology Highlight (s): Powerdome X™, Stealth Ring™ Weight: 135g (11-23)

Material: High grade tool steel cog cluster, Heat treated aluminum, Lowest range cog, Elastomer rings Speeds: 10-speed rear / 2-speed front

You have never seen a cassette that looks like this. The revolutionary machined design of the XX XG 1099 Cassette uses the same gruelling manufacturing techniques that produced the Power Dome road cassette. The middle eight cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise & strong cassette. Its a process that takes nine hours per cassette! Although designed to be the ultimate mountain bike cassette, the XG 1099 makes the ideal road climbing cassette. Combining a wide ratio that will get you up the most strenuous climbs, a low weight youll find hard to believe & fantastic good looks, this is a cassette like no other. Key

Features: 10 speed superlight cassette. 11-32 tooth range is ideal for arduous hill climbs. SRAM X-Glide shifting technology for flawless gear changes. X-Dome technology features the middle eight cogs CNC-machined from a single block of 4130 Chromoly steel. Recommended for use with SRAM PC 1091 & 1091R chains. Weight: 188g (PBK office scales, 11-32t ratio).

It might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. & it's also the biggest contributor to the Eagle™ drivetrain's ultra-smooth, precise, durable & quiet performance. The Eagle™ chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction & wear on chainrings & cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting & greater overall strength. HARD CHROME™ technology extends the chain's optimal performance life, & a Titanium Nitride coating on the Gold & Black models decreases corrosion & further reduces friction. Compatible with SRAM 12-speed MTB groupsets.

Features: Groundbreaking new chain design & technology The Eagle™ chain has been completely re-engineered, & is produced with new manufacturing technology All-new Eagle™ Power Lock® chain connector with FLOWLINK™ technology provides better chain-guiding & increased longevity The XX1 Eagle™ chain is the quietest, strongest & most wear-resistant chain in the world Unique features & design also provide significantly enhanced wear resistance on Eagle™ cassettes & rings
