All TA chainrings are made from a 7075 T6 aluminium that is heat treated, anodized then lazer engraved with all data and a marking to indicate correct orientation. The final polishing process produces a jewel-like piece of engineering that will remain corrosion resistant and offer a lifetime service.
These TA chainrings are compatible with 8,9,10 speed Campagnolo and Shimano triple road cranks.
