Origin8 Steel Single Speed Chainring Bolts

The Origin8 Steel Single Speed Chainring Bolts are designed specifically for single-chainring and single-speed cranksets, providing proper fit, secure clamping force, and long-term durability.

Unlike multi-ring hardware, these bolts are sized for single-ring applications, with an inside height of 4 mm when tightened and 7 mm total height, ensuring the chainring is held firmly without excess hardware length. The steel construction offers excellent strength and resistance to rounding during installation and removal.

This set includes five bolts and nuts, making it ideal for most single-ring crank configurations. While available in multiple finishes, this version features a clean chrome appearance that complements classic and modern builds alike.
