Shimano XT SM-CRM85 30T 1x Chainring - for M8100 and M8130 Cranks, Black

Adding to DEORE XT’s smooth drivetrain transmission, the new M8100 chain features SHIMANO’s DYNAMIC CHAIN ENGAGEMENT (DCE+) technology. An extended inner link plate of the chain connects seamlessly with new chainring tooth shapes for better chain retention and smoother, quieter pedaling. The new design reduces natural vibrations normally caused by the inner and outer chain plates rolling onto the chainring while also providing stronger contact between the two components. Special MTB gear teeth profile improves chain engagement and retention!
