Box Hex Lab Titanium Lock Ring

Product Overview

The Box Hex Lab Titanium Lock Ring is a cassette lockring designed for Shimano-compatible freehub bodies. CNC-machined from titanium with standard 1.375" × 24 TPI threading, it provides lightweight, corrosion-resistant cog retention for BMX race cassette drivetrains. Compatible with Park Tool BBT-9 and similar 16-notch tools.

Key Features

• Titanium construction - Titanium material provides high strength-to-weight ratio with excellent corrosion resistance and tool interface durability

• CNC-machined finish - Precision machining ensures accurate thread engagement and consistent clamping force on cassette cogs

• Tool-friendly material - Titanium's hardness resists deformation from lockring tool contact, preventing notch damage during installation and removal

• Lightweight design - At 7 grams, the titanium lockring reduces drivetrain weight compared to steel alternatives while maintaining clamping strength

• Standard Shimano threading - 1.375" × 24 TPI matches Shimano cassette freehub body standards for universal compatibility

Compatibility and Ideal Use Cases

Designed for BMX race bikes with Shimano-compatible cassette freehub bodies (Shimano, Excess, Elevn, and other Shimano-spline hubs). Standard 1.375" × 24 TPI threading fits all Shimano cassette drivers. Best suited for riders seeking weight reduction in the drivetrain or those who want color-matched components to pair with Box Hex Lab titanium cogs. Titanium construction prevents tool damage during high-torque tightening, making it ideal for riders who frequently service their drivetrain. Not compatible with freewheel hubs or non-Shimano cassette spline patterns.
