Turning things around, and around, and around.

While not the first onto the single-ring drivetrain scene, Shimano has nonetheless come to understand the clear advantages of such a system, and thus developed its own "1x" format. Using specially designed teeth and chainrings, cranksets like the Shimano FC-M9020 XTR 1x Trail Crank Arms demonstrate the company's expected engineering prowess in delivering riders the best of what they need.

As usual, Shimano forgoes carbon fiber for crank arm construction, and instead manipulates aluminum into superior function. Using cold-forging, the XTR Trail crankset's crank arms are shaped into a beefed-up version of the hollow-cavity HollowTech II arms used on the Race cranks. The Trail crank's arms are still technically HollowTech II arms, although they are less hollow and more reinforced for the greater impacts and torsional forces that trail- and all-mountain-riding typically produce.

The stainless steel teeth of the chainring of the single-ring Trail crank are not likewise hollow like the crank arms (as they are on the Race version of the same crank), but they do feature an alternating, semi-hook shape to aid in chain retention and the smoothness of the chain's engagement and disengagement with the ring. The trail crank's spider is the same found on all the new M9000-series XTR cranksets, and so it can accommodate any M9000 single- or double-ring combination in the series.

The Shimano FC-M9020-1 Trail 1x Crank Arms come in one color and in four lengths: 165mm, 170mm, 175mm, and 180mm. Their Q-factor is 168mm. The arms do not include chainrings or bottom brackets. Any and all chainring combinations that are compatible with these crank arms are designed for use with Shimano's 11-speed M9000 and M9020 drivetrains only.

Are these boost compatible? Thx

To answer your question in short; those cranks are not boost compatible. Unfortunately and to everyone’s astonishment, Shimano is not making a Boost XTR crankset yet. Most people are defaulting to the Next SL Crankset.

Unanswered Question

This crank comes with the caps to cover the bolt holes? Or just like its pictured.
