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.

  • Crank Arms only
  • HollowTech II forged construction
  • 168mm Q-factor
  • Will accept single and double chainrings

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.


Shoot me an email back and we can talk more about some options for you.


Unanswered Question

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