Carbon Structure chainring comes from the coupling of Ergal 7075 and the carbon fibre, that makes it perfectly compatible with the shapes of Shimano Dura Ace® crank set models 7900 (BCD 130mm) and 7950 (BCD 110mm).
The special feature of this chainring is the perfect compatibility with the original Shimano’s crank set, and the combination of a perfect shifting and an high stiffness guaranteed by the carbon fibre structure.
This technical solution allowed to obtain chainrings’ teeth 52 and 53 for BCD 130mm model, and 50, 51, 52 and 53 for BCD 110mm model.
Carbon Structure chainring will be available from November in the MICHE sales network.
