Is the Shimano SLX FC-M672 30t Middle Chainring Right for Your Trail Build?

The Shimano SLX FC-M672 30t is the middle chainring for SLX-generation 3x10 cranksets, designed as part of the 22-30-40t triple configuration used on trail-oriented all-mountain builds where maximum gear range is the priority. Built from aluminum at a 96mm BCD bolt pattern, the 30t middle ring serves as the primary chainring for most riding conditions, with the 22t inner handling the steepest technical climbs and the 40t outer available for fast descents and fire road sections. Shimano Dyna-Sys shift ramps and guide pins are built into the ring for smooth, reliable front shifting across the full drivetrain range.

Compatible with Shimano SLX FC-M675, FC-M672, FC-M670, and FC-M665 cranksets running 10-speed MTB drivetrains. 96mm BCD, 4-bolt mount, black finish. Sold as a single middle chainring. The 22t inner and 40t outer rings are available separately for building out or replacing the complete triple setup.

FAQ

Why replace just the 30t middle chainring?: The 30t middle chainring is the primary daily-use ring on a 10-speed triple. It typically wears faster than the inner or outer rings and benefits from independent replacement when shifting performance degrades or visible wear appears.

Will this 30t fit other Shimano triple cranksets?: Yes, on cranksets that share the 96mm BCD 4-bolt middle chainring spider. Always verify your specific crankset's BCD and bolt pattern before ordering.

Is this chainring compatible with 11 or 12-speed chains?: 10-speed Hyperglide chainrings are optimized for narrower 10-speed chains. Using an 11 or 12-speed chain on a 10-speed chainring will work but may cause sub-optimal shifting.

Best For

SLX FC-M672 owners replacing a worn middle chainring on a 10-speed triple build, or builders sourcing a 96mm BCD 30t middle chainring for compatible Shimano triple cranksets.
