Your cart is empty.Shimano craftsmanship reaches new heights with the XTR 12-speed groupset. These Hollowtech II crank arms feature a lighter and stiffer design, and simple-to-change direct-mount chainrings with a single key release, allowing you to feel things out with your new 12-speed configuration and find the perfect gear ratio for you. If you're a little confused by Shimano's offerings of both the FC-M9120 and FC-M9100, you're not alone. With two offerings in this top-tier package, the differences may be difficult to spot at first glance. Shimano builds the M9120 with a beefier, more robust design than the XC-oriented 9100, ideal for riders charging hard and having up-close-and-personal encounters with rowdy sections of trail that give your crankarm the occasional bash. On top of the beefier construction, the M9120 crankarms boast a wider Q-factor that lands in at 168mm, in comparison to the 158mm of the 9100. This wider Q-factor increases stability when you're descending at high speeds and offers a bit more chainstay clearance for beefier 148-millimeter Boost spacing in the back. As its name suggests, this particular XTR M9120 Crankset is intended solely for bikes with Boost 148-millimeter rear axles, with its 52-millimeter chainline reflecting the outboard move to accommodate Boost axle spacing. The crank arms come alone, without chainrings, but can be paired up with either one-by or two-by options in a huge range of sizes to best suit your riding needs. Additionally, Shimano is offering the XTR 9120 in a range of sizes from 165mm to 175mm, so shorter riders, or those with gravity-oriented appetites who want a little more clearance, can be decked out with the perfect crank length, too.

My new Giant Anthem Pro 29-3 came with a proprietary Praxis crank and ring. I've ridden an old '97 MTB for years so I was not familiar with this piece or its reason for being.It had a weird non-drive crank, BB bearing and axel diameter but the real problem was the 172mm crank length. Extra weight and compromised handling not being my bag I decided to swap immediately. All my bikes have for years been 165 (I'm 5'6") and I don't like to have an outlier. Not only the right size for me and more standardized but it also weighs nearly 100g less! Somehow it feels more sturdy as well. This could be the $35 Shimano BB I had to install (and it needs a ring too!) but altogether it just feels so much more solid.Get in touch if any of you want an unused Praxis 172 with brand-new BB!

I like the design and it has 38 teeth,my dislike is it cost 3x’s of Deore XT. I installed it on my 2021 Giant Trance Advanced Pro 29-1
