Shimano XTR FC M9020 Trail 11 Speed Crankset 3424T. If you seek a mountain bike crankset as bold, strong, and innovative as the way you attack the most demanding singletrack, then feast your eyes on the Shimano XTR FC M9020 Trail 11 speed edition. The latest and greatest iteration of Shimano's flagship XTR group is just plain ridiculous in all its features that make it the best money can buy, and in their Rider Tuned design ethos there's two XTR versions: Race, super light for cross country racing, or this Trail edition, stouter to handle the rigors of all mountain and enduro riding. The XTR Trail version features cold forged aluminum crankarms that are incredibly strong, stiff, and built to withstand whatever the trails throw at them. This crankset boasts the most advanced mountain bike chainrings ever produced, that utilizes a combination of titanium, carbon and aluminum to maximize durability and lightness. You'll love the close step gearing of the double chainrings and new 11 speed XTR cassette means there's never a big gap in gears when shifting through the range. Perhaps coolest of all, the crankset's modular design means you can run a 1x, 2x, or 3x chainring set up to provide incredible versatility and the ability to hone gearing to perfection.
