After several rides on my Tallboy Carbon, I seemed to be getting a lot of chain slap on really rough sections of the trail. I ignored it at first, but then started to wonder if I might be doing damage to the frame. My Tallboy has a protective carbon wrap on the chain stay, and I added a neoprene wrap as well, but you still never know what kind of damage might happen if the chain continues to slap the same spot on the frame over and over. So, I decided to swap out my standard SRAM X9 rear derailleur for one of their "Type 2" models.
The SRAM X9 Type 2 Rear Derailleur is a big improvement over the standard X9 derailleur. I've been riding with it for several months now, and so far, shifting is buttery smooth, and chain slap has been eliminated. Additionally, the locking feature makes it easier to remove the rear wheel. This thing just plain works... and I'm not sure why anybody would opt for the standard rear derailleur.
