Chainring Shimano XT SM-CRM81 96mm for FC-M8000-1 11-speed 30T

Shimano XT 11-speed chainring SM-CRM80 with 30 teeth and 96 mm bolt circle for 1-speed FC-M8000 crank. The dedicated XT 1x chainring features retention technology with a unique tooth profile that eliminates the need for chain retention devices. The 1x11 tooth profile on the XTR and DEORE XT chainsets combine wide steel teeth shape with special hooked teeth design for lasting chain retention especially over uneven terrain. These improvements increase chain retention force by 150%, increasing chain life and drastically reducing the possibility of a dropped chain.
