By reducing the frequency of replacements, you can spend more time riding and less time on maintenance. Furthermore, its lightweight design helps to reduce the overall rotational mass of your crankset, contributing to quicker acceleration and a more responsive feel, especially noticeable during climbs and sprints.

Main Features:

Expertly crafted from a high-strength 7075 T6 aluminum alloy, this chainring offers an optimal balance of strength, stiffness, and low weight. The advanced material properties ensure that power is transferred efficiently from your legs to the drivetrain without flex. The classic 5-hole design and standard 130 mm BCD (Bolt Circle Diameter) provide broad compatibility with a wide range of double (2x) road cranksets, making it a versatile choice for many setups. Specifically designed as an inner position chainring with 39 teeth, it is optimized for use with 2x 9-speed and 2x 10-speed systems, ensuring perfect harmony with your existing components.
