Like the latest XTR, options are the emphasis of the new Deore XT. The debut of the Shimano Shadow RD yields a third rear derailleur option, joining the Top-Normal and Low-Normal versions. A Shadow RD places priority on a low profile design and less body movement for those enthusiasts that are most at home on extreme technical trails
Shimano presents a new XTR rear derailleur RD-M972, developed with the revolutionary Shadow technology that was introduced recently in the new Deore XT group. Shadow realizes an extra thin profile to minimize the chance of getting hit by a rock. A tree trunk. Or whatever else lies waiting on the trail
The new 10-speed XTR rear derailleur sees a re-engineered architecture that provides a smooth, linear feel at the shifter and is remarkably stable despite suspension movement, trail chatter or inevitable cable contamination.

The 10 speed SIS 105 rear derailleur integrates the wide link design prominently featured in both Dura-Ace and Ultegra derailleurs to not only promote quick shifting, but to preserve the pivots for greater durability and long term crisp shifting performance. The new derailleur is available in both short and medium cage lengths for double, compact, or triple crank configurations
Shimano RD-7900 Dura-Ace Rear Derailleur with a new carbon fiber rear pulley cage, the rear derailleur loses another 16 grams while maintaining durability and improving performance. The new design is compatible with wider range cogsets and can accommodate a maximum 28 tooth cog. The available wider range creates even better compatibility with compact cranksets
Shimano redesigned the Ultegra rear derailleur this year to optimize performance and decrease weight yet again. The beauty is that all the performance enhancements of Dura Ace come out in this new Ultegra piece. Well, everything short of the super pricey carbon fiber cage. The wider outer link reduces shifting deflection, while the redesigned cage is optimized up to the new 28 tooth cog available in the cassette. And of course, it's lighter too
