The lightweight and durable 11 speed-compatible FC-M7000-11 chainring (1x11 and 2x11) teeth feature Shimano’s new Dynamic Chain Engagement technology and are designed for the different power outputs delivered in each ring, offering enhanced chain retention, driving rigidity and highly efficient, precise shifting. In the 2x11 set up, close gear ratio combinations ensure a minimum shifting gap between gears and allow the rider to maintain an efficient rhythm throughout the complete range of gears. Set up options are kept to a chainring capacity of 10-teeth with three options (34-24T, 36-26T and 38-28T). 1x11 riders have the option of 30T, 32T or 34T chainrings to combine with two cassette options (11-40T and 11-42T). B-spec options are also available in double and single ring set ups to ensure chain lines can accommodate 148mm rear hubs.
