Avian Alloy Chainring Bolts - Red

Product Overview

Avian Alloy Chainring Bolts are lightweight aluminum chainring mounting hardware available in short and long lengths. Anodized in red with a 5-bolt design, these bolts provide secure chainring attachment while reducing weight compared to steel hardware. Sold as a complete set of 5 bolts and nuts.

Key Features

• Lightweight alloy construction – Aluminum bolts reduce rotating weight to 0.3 ounces per set (5 bolts), significantly lighter than steel or chromoly alternatives
• Two length options – Short (6.4mm/6.4mm) for standard chainring/spider combinations; Long (8.9mm/6.4mm) for thicker chainrings, bash guards, or spacer setups
• Red anodized finish – Color-matched hardware complements red components or adds accent color to bike builds
• Complete 5-bolt set – Includes all 5 bolts and matching nuts required for standard 5-bolt chainring mounting
• Standard tool compatibility – Requires 5mm Allen key and chainring nut wrench (such as Park Tool CNW-2) for installation

Compatibility and Ideal Use Cases

These bolts fit any 5-bolt chainring and spider combination with standard 5-bolt BCD (bolt circle diameter) patterns—verify your chainring uses 5-bolt mounting before ordering. The short length (6.4mm/6.4mm) works for most standard chainring and crank spider setups. The long length (8.9mm/6.4mm) accommodates thicker chainrings, chainring guards (bash guards), or setups requiring spacers between the chainring and spider. Ideal for weight-conscious BMX racers, freestyle riders building color-coordinated bikes, or anyone replacing worn or damaged chainring bolts. The aluminum construction saves weight but is less durable than chromoly under extreme torque or impacts—chromoly versions (0.8 oz) are available for riders who prioritize strength over weight savings. Installation requires a 5mm Allen key for the bolt heads and a chainring nut wrench to hold the slotted nuts—attempting installation without proper tools can strip bolts or nuts.
