This Shimano Ultegra 6750 chainring is perfect for replacing the old or worn-out existing chainring on your road bike's Ultegra chainset. Although they may differ in style and shaping, they’re also compatible with the 10 speed Shimano 105 FC-5750 and Dura-Ace FC-7950 10 speed chainsets. Genuine Shimano replacement part. For use with Shimano Ultegra FC-6750-G 10spd Compact Double Chainset - 50-34T. Please Note: Although these chainrings are compatible with Dura-Ace 7950 cranks, the style/shaping is different. Please Note: These individual chainrings both have a "B" type match for the shifting pins/ramps, so operate best when paired with other Shimano chainrings that have this shifting pin/ramp type. We suggest that you consider purchasing both the 50T and 34T together to ensure the best gear shifting performance.
