The Shimano SLX 10-speed chainring for the FC-M670 crankset
This Shimano SLX chainring is an original spare part for the FC-M670 10-speed cranks. It can be used for the 24-32-42 and 26-36-48 tooth gradations. With its specific tooth profile and high strength, it fits perfectly into the HyperDrive system of the front drivetrain components.
Application: All Mountain, Trail, Cross Country, City & Touring
Mount: 104 mm bolt circle diameter, 4-arm
Teeth: 32 t, 42 t, 48 t
Combinations: 24-32-42 t, 26-36-48 t
Material: steel fibreglass composite (32 t), aluminium (42 t + 48 t)
Note: The FC-M670 with chain guard requires a special chainring.
Shimano´s front shifting system is based on the HyperDrive concept. The front derailleur, the HG chain and SG-X chainrings work in a coordinated combination to make shifting more reliable, faster and more accurate. Without HyperDrive, problems are quick to appear when shifting on the big chainring, especially when under load. Shimano's HyperDrive system solves those problems. The SG-X chainrings, Wide Link front derailleur and HG chain work together to improve chain control to provide precise and reliable front derailleur shifting that is especially beneficial in severe off-road riding conditions. The chainrings have an exceptionally high torsional stiffness. The tooth profile is specifically shaped to allow the chain to glide in both directions and be picked up smoothly while shifting.

Note: The 24 tooth chainring (Y-1LU24000) is identical to SLX chainring FC-M780. The 26 tooth chainring (Y-1KS26000) is identical to SLX chainring FC-M771-K. The 36 tooth chainring (Y-1MP98020) is identical to FC-T781 chainring.
Note to Type Designation:
The type designations (with one or two letters) indicate that the chainrings can be combined with each other. Since the large rings have specially shaped teeth and shifting aids that make it easier for the chain to climb, full shifting performance is only guaranteed with matching small rings - and vice versa. A chainring of type XY should therefore only be ridden with a chainring of type XY. The same applies to all other types.
