JTwrote a review of SRAM X9 Type 2 Rear Derailleur on August 4, 2014
Familiarity: I've put it through the wringer
Put this on a 34/44 x 11/32 set up using Force 10s shifters and it works great. No more chain slap! With this new found silence I plan to sneak up on other racers and quietly throw down a few gears as I blow past them.
