Cut from top-end 7075 T6 Aluminium, the 11 Speed X110 Inner Chainring uses a specific 4x110mm asymmetric bolt pattern, making it compatible with Shimano’s Ultegra, Dura-Ace and 105 road bike cranksets. It also boasts teeth with a computer aided design (CAD) profile, which ensures it brings you smooth operation and clean shifts between chainrings.
Please Note: For complete compatibility, you must replace both inner and outer with TA rings.
Please Also Note: These chainrings are designed to be compatible with the modern chainsets that have a cutout on one arm, they are also backwards compatible with the earlier chainsets that do not have the cutout.
