    More everything.

    Shimano’s famous for its commitment to trickle-down tech and, sure enough, there’s plenty top-shelf inspiration to be found in the XT FC-M8000-B1 Boost 1X Crank Arms. Obviously, they’re designed to play nicely with Boost 148 rear axles, with a 3mm offset chainline that keeps your links running smoothly between cassette and chainring. The more expensive XTR’s Hollowtech II construction has also trickled down to XT, letting you save weight and cash, and the new 1x11 platform lets you enjoy so much granny gear that you’ll practically be moving backwards on those puke-inducing climbs.

    Lightweight. Durable.

    • Familiarity: I've put it through the wringer

    Because that's what defines XT, right? This is a great choice for people who are prone to bashing cranks on rocks, but still want something that is good quality and will hold up to said beating.
