SRAM X5 9 Speed Rear Derailleur 2013
Sram X.5 Rear Derailleur 2012 features high-quality materials and precise engineering for long-lasting strength and smooth performance.
Put it on my commuter. Not the lightest but shifts like a champ. Looks nice too. I give it 4 out of 5 chili peppers.
I purchased this part about 2 months ago while outfitting my hardtail with 8 speeds in the back. All was well until my second ride, through a bumpy section the derailleur basicall broke in half, less than 10 miles on part...struck me as strange because my other SRAM derailleur has survived over 7 years of abuse.
