Shimano demonstrates their ability to re-imagine components with their redesign of the XTR rear derailleur. The minimalist design outer X plate both works functionally as a lighter (less metal) and stronger (wider cage twists less), better shifting derailleur, but aesthetically as a branded part where the function is integral to the fashion.

This is the Low Normal version of the derailleur. Shimano believes this will appeal to cross-country riders who do lots of climbing. Having the spring work in reverse—pushing the chain toward the lowest gear, or largest cog--makes the shifts onto the larger cogs easier and faster. Good for those who sometimes unship their chain panic-shifting when grinding up steep hills.
