Many people might be confused about why we put #‎steel_construction while it is made of 7075 Aluminum forged through CNC.

Well, Alter_Cycles SC series Chainring was inspired by the image and patterns of the Structural Steels often seen in construction worksites. Hence it was given the name SC (Steel Construction) series.

While creating this chainring, we had an idea that our product is not only a piece of bike part but also a piece of art in order to satisfy our users on both the quality and appearance of our products.

Thank you for your supports, we will present to you the best quality from Taiwan!
