Product details

The First Components AL7075 BCD chainring is an essential accessory for ambitious road cyclists. Made from a high-quality AL7075 aluminum alloy, it combines lightness and durability, resulting in excellent stiffness and efficient power transfer. The corrosion-resistant surface ensures a long lifespan, even under harsh weather conditions.

The precise machining of the teeth allows for smooth gear changes, while the optimized tooth shape improves chain retention and minimizes the risk of chain drop. Additionally, the modern design adds an appealing aesthetic to the bike.
