SRAM X0 9-Speed Rear Derailleur

Information from: http://www.sram.com/sram/mountain/products/sram-x0-9-speed-rear-derailleur.

TOUGH ENOUGH FOR WORLD CUP DH, LIGHT ENOUGH FOR WORLD CUP XC RACING. Carbon, titanium and alloy create this beautiful yet functional piece of art. Three available cage length options and a weight of less than 200 grams makes the X.0 rear derailleur the number one choice.
