EXACT ACTUATION
When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing & exact cable tension. The result: the easiest index shifting system to set up & it stays that way.
X-Glide
Imagine being able to shift smoothly at any time, no matter what. We’re talking full-power shifts. Up, down, whatever the trail demands. The benefit of the X-Glide drivetrain is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you’ll never again compromise your speed & power in unpredictable off-road terrain. Here’s how we did it: TRUVATIV’s crank engineers threw away the old standards & developed a new chainring geometry from the ground up. They precisely paired the different-sized chainrings & redesigned where & how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities. No more missed shifts, ever. X-Glide puts you in THE RIGHT GEAR, right now.
Specifications for XX Front Derailleur
Sometimes all you need is a fresh coat of paint. With revised graphics to match SRAM RED e Tap components, the Powerdome X™ is still the most advanced cassette ever made. It's super light, deadly silent, & 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 Stealth Ring™ elastomer to reduce vibration & noise. Cutouts on the rear cog further reduce weight & add stiffness. It's the final piece in the drivetrain puzzle, & paired with the new SRAM Red rear derailleur, it delivers ultra-fast, ultra-quiet shifts that will always put you in the right gear. Heat-treated, high-grade tool steel provides 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 design, material & production process ISO 4210 compliant
