I've had nothing but problems with shimano 12spd. 2 failed xt freehubs(both creaked, one fell apart, the other locked on), 3 xt shifters broke(plus my buddy has had 2 xtr's break) due to tiny spring coming unraveled and letting the pawl flop around. Not to mention the two clutch mechanisms that corroded out before I figured out they came pretty much ungreased from the factory... Shimano has warrantied it all, no questions asked. But god damn, they need to get their quality control together!
The chain, cassette, and chainring are great. Although the chain still falls off the 51t if you back pedal once things get a little worn. My cranks came with the DM tool, actually really like the it. Nice sturdy bit of steel.
