Insight Alloy Crank Bolt M20x10.7 - DXR

Product Overview

The Insight Alloy Crank Bolt M20x10.7 DXR is an aluminum replacement crank bolt designed for securing the non-drive side crank arm to the spindle on Shimano DXR and compatible two-piece BMX cranksets. Manufactured from 6061-T6 aluminum, this bolt provides a lightweight alternative to steel crank bolts while maintaining the clamping strength needed for proper crank arm installation.

Key Features

• Shimano DXR Compatible – Specifically designed to fit Shimano DXR cranksets and other compatible two-piece crank systems
• M20 Thread Size – Standard thread diameter for common BMX two-piece cranksets
• 10.7mm Length – Appropriate bolt length for proper crank arm engagement and secure clamping

Compatibility and Ideal Use Cases

Compatibility Requirements: Designed specifically for Shimano DXR cranksets and other two-piece BMX cranks using M20 x 10.7mm crank bolts. Verify your cranks are DXR-compatible or use M20 threading with 10.7mm bolt length before purchasing. Not compatible with one-piece cranks, three-piece cranks with different threading, or cranks requiring different bolt specifications.

Installation Note: Aluminum crank bolts require proper torque specifications to avoid cross-threading or stripping. Follow manufacturer torque recommendations and use appropriate tools for installation. Do not overtighten.

Ideal for weight-conscious BMX racers running Shimano DXR or compatible cranksets who want to reduce drivetrain mass through aluminum hardware. At just 5 grams, this bolt saves measurable weight compared to steel alternatives while maintaining adequate clamping strength for proper crank arm installation. Best suited for riders who perform regular maintenance and understand proper torque specifications for aluminum hardware. Suitable for competitive racing where small weight savings add up across multiple components. Less appropriate for very heavy riders or those subjecting cranks to extreme loads, where steel hardware provides additional safety margin.
