ELEVN Aluminum Cogs

Product Overview

The ELEVN Aluminum Cogs are precision CNC-machined rear sprockets designed for BMX race applications using Shimano-compatible cassette hubs. Manufactured from 7075-T6 aluminum alloy, these cogs provide a lightweight alternative to steel sprockets while maintaining strength for racing use. Available in tooth counts from 14T to 18T, they allow riders to fine-tune gearing for different track layouts and rider preferences.

Key Features

• 7075-T6 Aluminum Construction – High-strength aluminum alloy delivers reduced weight compared to steel cogs while maintaining durability for racing loads
• CNC Machined – Precision manufacturing ensures accurate tooth profiles for smooth chain engagement and consistent drivetrain performance
• 5mm Wide Contact Surface – Wider hub interface distributes clamping force across a larger area, reducing stress on the cassette body and minimizing the risk of hub damage
• Shimano Cassette Compatible – Standard Shimano spline pattern fits most modern BMX race cassette hubs
• Multiple Tooth Count Options – Available in 14T, 15T, 16T, 17T, and 18T configurations for gearing customization

Compatibility and Ideal Use Cases

Compatible with Shimano-standard cassette hubs commonly found on BMX race bikes. Verify your hub uses a Shimano cassette body before purchasing—these cogs are not compatible with freewheel hubs or other cassette standards.

Ideal for BMX racing where weight reduction and gearing flexibility are performance priorities. The range of tooth counts allows riders to optimize gearing ratio for specific tracks, rider size, or acceleration preferences. Aluminum construction saves weight over steel cogs, making these suitable for competitive racers looking to reduce rotating mass. The 5mm contact width provides additional protection for high-end cassette hubs by spreading load across a wider surface area.
