Pack Chainring Bolts Elevn 6.5×4mm Alloy Double Clamping

Product Overview

Elevn chainring bolts are lightweight aluminum fasteners designed for BMX race cranks. CNC-machined from 7075-T6 aluminum with dual hex interfaces on both bolt and nut, they allow simultaneous clamping from both sides for secure chainring attachment. At 6.5mm length, they accommodate both four-bolt and five-bolt chainring configurations.

Key Features

• 7075-T6 aluminum construction – Higher-strength aluminum alloy compared to standard 6061 provides increased durability under chainring clamping loads while maintaining low weight

• Dual hex interfaces – Hex socket on both bolt head and nut allows wrench access from either side, preventing rotation during installation and simplifying tightening

• 6.5mm length – Extended bolt length accommodates thicker modern four-bolt chainrings as well as standard five-bolt rings without bottoming out or leaving excessive thread exposed

• Laser-etched Elevn logo – Permanent branding provides visual detail without adding weight or affecting function

• Reduces rotational weight – Aluminum construction weighs less than steel chainring bolts, reducing mass at the drivetrain for improved acceleration

Technical Specifications

• Finish: Anodized with laser-etched logo
• Compatibility: Four-bolt and five-bolt chainrings

Compatibility and Ideal Use Cases

Designed for BMX race cranks using four-bolt (104mm BCD) or five-bolt chainring patterns. The 6.5mm length fits modern thicker chainrings without requiring washers or spacers. Best suited for competitive racing where rotational weight reduction improves acceleration and riders want clean aesthetics with functional hardware. Dual hex design simplifies installation by allowing both sides to be held during tightening, preventing nut spin. Not compatible with single-bolt or proprietary chainring attachment systems—verify your crank uses standard four-bolt or five-bolt chainring mounting before ordering.

Note: Set includes 5 bolts (verify your chainring requires 4 or 5 bolts before ordering).
