This SRAM X.0 XO 9-speed mountain bike rear derailleur and shifter set is brand new and comes in its original packaging. The set includes both the left and right shifters, as well as the rear derailleur, all made of high-quality materials such as aluminum and carbon. The set is compatible with SRAM bikes and has a long cage derailleur cage length.

Both were manufactured in 2010. Rear Derailleur is a Carbon Fiber Long Cage. The shifters are aluminum and carbon fiber. Both will work with Shimano and SRAM 3x9 drivetrains.

I prefer to sell them as a set, since they complement each other perfectly.

Perfect for a retro 1999s mountain bike build.

Let me know if you have any questions or concerns.

Thanks!

Jeff
