The Shimano Deore FC-M6120-1 crank features an entirely new construction, using direct mount chainrings, special gear tooth profile for improved chain retention, and a 178 mm Q-factor that is compatible with 148 mm O.L.D. frames.

• Great value Deore M6120 2-piece design chainset for 12-speed Dyna-Sys MTB HG-X transmissions
• Forged crank arms rigid whilst being incredibly strong and durable
• Designed to be used with a HollowTech II integrated bottom bracket that uses a wide bearing placement with a large axle diameter for increased stiffness, efficiency and added durability, the bottom bracket does not come with the chainset but can be purchased separately
• Lightweight aluminium chainring
• We recommend that the bottom bracket is initially installed by a bike shop to ensure perfect facing and fit
• 55 mm chain line for use with 148 mm O.L.D. frames
• Direct mount chain ring
• 12-speed Dyna-Sys compatible
