Shimano SLX M660 3X10 Dyna-Sys Crankset

Equipped with 42/32/24T chainrings, the new, closer-ratio, Shimano SLX M660 3X10 Dyna-Sys Crankset is designed to significantly increase shifting efficiency and energy transfer when combined with the wider-ratio Dyna-Sys 10-speed cassette. The combination allows you to spend more time in the middle chain ring, makes it easier to ride in the 42T chain ring, and provides a faster, smoother drop to the 24T ring. Closer gear ratios deliver consistent power, allow you to maintain a steady cadence over varying terrain and result in fewer missed shifts and dropped chains.

Specifically designed for compatibility with Dyna-Sys 10-speed mountain drivetrains
Hollow-forged aluminum arms with a reinforced spider and integrated HollowTech-II bottom-bracket spindle deliver efficient power transfer
