For complete compatibility you must replace both inner and outer with TA rings.

Please 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.

TA only make their chainrings from the best 7075 t6 heat treated aluminium sheet. Suitable for their own cranksets and other manufacturers like Shimano, Campagnolo, SRAM and others. The teeth are cut in the traditional manner on a lathe which produces a much better and more accurate tooth form than pressing which is used by most chainring manufacturers.
