The product

VOR HOLLOWGRAM

Made from the finest aluminium alloy (7075-T6 Ergal), they go through several CNC machining processes and undergo rigorous testing to guarantee maximum performance on the most important World Cup race courses. All our chainrings are anodised to increase surface hardness and improve durability over time. Extremely light, this chainring features synchronised narrow-wide teeth that keep the chain perfectly seated even in the toughest conditions, making a chain guide unnecessary.
