TA only make their chainrings from the best 7075 T6 heat treated aluminium sheet. 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.

Suitable for 9/10/11x chainsets
For middle triple specific rings use TBF..
For inner triple specific ring use TAH..

For ideal shifting we strongly recommend combining the rings with a gap of between 12 and 16 teeth.
