Shimano SLX FC-M672 Chainring - 30t | 96mm BCD | 10-Speed
What Is the Shimano SLX FC-M672 Chainring For?
The FC-M672 is a 30-tooth middle chainring designed for Shimano SLX triple-chainring cranksets using the 96mm BCD (bolt circle diameter) 4-bolt pattern. It is the correct middle ring for the SLX FC-M672 crankset configured in the 40-30-22T triple setup, where the 30T ring handles mid-range gear combinations typically used on moderate climbs and rolling terrain. The ring uses Shimano's Hyperglide+ shift ramp geometry with ramp and pin placement designed to facilitate smooth upshifts and downshifts between the 30T middle ring and the 22T inner and 40T outer rings in 10-speed triple operation. This optimized ramp geometry is specific to the triple-ring spacing and chain line of SLX-spec triple cranksets.
The FC-M672 30T chainring is also cross-compatible with several other Shimano MTB cranksets that share the same 96mm 4-bolt BCD, including the FC-M7000, FC-M622, Deore FC-M612, and FC-M523. This makes it a useful replacement ring for any rider running those cranksets in a triple-ring configuration who needs to replace a worn middle ring without changing the full crankset. The ring is aluminum construction with the standard black finish matching the SLX component aesthetic. For riders on SLX or compatible triple-chainring setups needing a direct-fit 30T middle ring replacement at 96mm BCD, the FC-M672 is the correct specification.
