Shimano's SLX group is the latest to get an overhaul, benefitting from many of the technologies and advancements in their more expensive lines.

The SLX FC-M7000 cranks now feature the Dynamic Chain Engagement (DCE) 1x11 tooth profile and 3D composite chainrings. The DCE profile is said to run faster and increase chain retention force by 150-percent. Stainless steel chain ring teeth provide long life. 1x11 and 2x11 cranks are available with optional +3mm wider spindles for 148 OLD hubs. A new, lighter bottom bracket improves durability, has reduced seal drag and is available in press-fit or threaded options.

On the brake side, a new integrated master cylinder gives the SLX line a sleeker look, saves weight and frees up valuable handlebar space. There are also new SM-RT70 CENTER LOCK disc rotors that improve heat dissipation through refined shaping and an alloy adapter.

The SLX RD-M7000 rear derailleur features Shimano Shadow RD+ technology and refined geometry for increased stability. Shift effort has been reduced by 20%, the clutch is still adjustable, and it's both 1 and 2x11 compatible.

The new CS-M7000-11 11-speed HYPERGLIDE cassette utilizes lighter aluminum spider construction, aluminum and steel cogs, and is available in 11-42T and 11-40T options.

Finally, the shifters are lower profile and feature improved longer levers that decrease shift effort by 14 to 20%. They are available in two I-spec options or band clamps.
