PRODUCT DESCRIPTION

Shimano XT M780 3X10 Crankset

When Shimano created its 10 speed Dyna-Sys range of drivetrain components, one of the key pieces to receive a significant makeover was the crankset. The gearing was reworked to improve front shifting by taking advantage of the wider range of the 10 speed cassette. The chainrings themselves were completely reworked to fit perfectly with the narrower HG-X 10 speed chain. The middle ring even borrows a page from XTR with carbon fiber reinforcement for added durability and stiffness. Carrying over from the 9 speed version is the same Hollowtech II design and ease of set up. Bottom bracket cups are included and will fit both 68 and 73mm shells.

Please note, Shimano's Dyna-Sys range of 10 speed components are designed to work as a complete group. This crank is not compatible with 9 speed drive trains.

In-house measured weight including bottom bracket is 866g.

  • Dyna-Sys: 10-speed drivetrain
  • Better shifting performance
  • Smooth pedaling
  • 42-32-24 close step gearing maintains momentum
  • HOLLOWTECH II design for optimum balance between lightweight and rigidity
  • Durable steel/carbon composite middle chainring
  • Specific Designed Tooth for HG-X Chain provides light action and reliable shifting
If you prefer not to run a front derailleur, these cranks can be easily converted to a 1x setup by removing the inner and outer chainrings and replacing the middle with a narrow-wide ring, like this one from Wolf Tooth. (please note: results may vary depending on frame)

Terrific crankset! - Apr 11, 2015

Super solid and totally reliable. Santa Cruz spec'd this on my carbon Tallboy. I've ridden this crankset hard (mostly XC but some AM/Moab/GJ thrown In for good measure) for nearly 4 years. Teeth are worn but other than that it still rocks. Looked at stepping up to XTR. But for this price? Can't be beat!! Highly recommended

Love these! Light, strong and come in 165mm. I have very short legs and the 165mm length is much more comfortable.
