Description

SHIMANO DEORE XT Crankset

Since their introduction many years ago, Shimano Hollowtech cranks have been the best cranks you can put on a mountain bike. Extremely strong, remarkably lightweight, and stiffer than a straight shot of whiskey.

The crankarm construction exemplifies the level of craftsmanship that's put into a Shimano crankset, utilizing a 3D hollow bonded structure to further reduce weight and increase stiffness. Chainrings are easily exchanged with the new direct-mount system and the cranks can be swapped between single and double front chainring setups. The spacing and chainline are optimized for Boost-spaced rear hubs for proper cassette positioning.

Features:

  • Special MTB gear teeth profile improves chain engagement and retention
  • Hollow forged crank maximizes power transfer while limiting weight
  • Superior chain retention
  • Rigid and lightweight design for aggressive trail riding
  • Spacing: Boost
  • Q-factor: 178 mm
  • Chainline: 55 mm
  • Weight: 616 g (28T), 630 g (30T), 628 g (32T), 642 g (34T), 660 g (36T)
