XTR. Those three letters represent the very best, the pinnacle of mountain bike technology. Since its debut XTR has been the absolute standard for lightness, durability and performance. XTR is the benchmark by which all other off-road components are judged. And they've just moved it up again.
The new XTR isn't just a refinement of what's come before - it's an almost total overhaul that completely changes the riding experience. Ride with quicker, faster control and response, anywhere you want. Whether you're a cross-country racer, an all-mountain rider or just someone who wants the very best, new XTR is engineered for the way you ride.
The wide pivot link design boosts strength and rigidity. Flex is suppressed, creating sharp, precise shifts that are faster and smoother, even from low to high gears off of the saddle.
Also, Shimano uses a Double Servo-Panta Mechanism which keeps the guide pulley close to each sprocket to allow for smooth and precise shifting you've come to expect with Shimano.

Please note:
'Low Normal Return Spring' is the same as:
This derailleur naturally rests in the large cassette sprocket. It works in the opposite direction to a standard spring direction rear derailleur. It will still work with any 8 or 9 speed shimano compatible shifter and drive-train, but in the opposite direction.
