Shimano's update to Deore XT has brought it almost on par with its pro-level sibling, XTR, and aside from a few weight and aesthetic differences, it's pretty tough to tell the two apart. If the thought of abandoning your granny gears forever in favor of a one-by makes your stomach flip, chill out and know that the Shimano XT FC-M8000 Double Crankset won't force you to do any such thing. Benevolently bestowed with trickle-down technology in the form of Shimano's Hollowtech II arms, the FC-M8000 comes prepared for all kinds of off-road rowdiness, with a hollow spindle to save weight and a rugged aluminum construction. Shimano made the M8000 straightforward to install and set up, and it includes two improved 3D composite chainrings to hang onto your chain with precision, without slowing down its orbit. The bottom bracket even got to join in on the update fun as well, returning with a more efficient seal, lower weight, and improved longevity, giving the crankset the sleeker functionality to match its equally streamlined aesthetics.
