Shimano XTR FC-M9020-1 1x Trail Crank Arms

Drool-worthy.

Without getting into any of Shimano’s new technology, just take a look at the XTR 1x Trail Crank Arms. They’re stunning. Shimano’s slow march back towards aesthetically-pleasing parts has been good to see, and the new XTR kit looks to be the crowning achievement.

Now, while Shimano maintains that front derailleurs still have a place in mountain biking, the vast majority of us have seen the single-ring light. So, Shimano’s made their XTR arms available for those of us who wish to use a single ring but can’t resist the glossy gray allure of Japanese drivetrain parts. The Trail version of these arms, which you see here, is constructed using Shimano’s tried-and-true HollowTech II technology, though the Trail version is a little less hollow than the Race versions.

The XTR Trail Crank Arms include neither a chainring or a bottom bracket –it’s up to you to find the perfect match for your frame and riding style and put together the ultimate drivetrain.

Stiff and Strong

  • Familiarity: I've put it through the wringer

no crank is stiffer than XTR. Enough said.

Not bad for a set of cranks

  • Familiarity: I've put it through the wringer

At heavily discounted prices these are typically going for, they aren't a bad choice. You can save a little bit of weight, gain a little bit of strength and save a fair amount of money by going with Race Face Turbine cranks instead, though. Ultimately, I chose these for vanity in matching my XTR drivetrain. That sense of vanity is easily dashed, though, when you find that the XTR graphics come off if you so much as rub on the cranks. I had placed protective tape on but the tape wore down and peeled, taking the graphics with it.

yeah

    yeah

    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.
