Material Excellence & High-Strength Security

Chaser Sports relies entirely on high-strength 7075 aluminium alloy to construct this low-profile locking cover. Choosing this high-grade material ensures that the fine threads can reliably withstand standard cassette installation forces of 35–40Nm without stripping. To boost the product’s premium finish, it undergoes a dedicated CNC polishing process before colour oxidation, providing a durable, high-gloss surface that resists tool marring and adds a clean accent to your drivetrain.

Freehub Compatibility

This component is engineered with precise spline geometry tailored to fit specific drivetrain configurations:

• HG (ROAD) compatible: Featuring a verified checkmark layout, this lockring fits perfectly onto classic and modern Shimano Hyperglide (HG) pattern freehub splines.
• SRAM XDR Not Applicable: Marked explicitly with a red cross icon, this lockring will not thread onto SRAM XDR or XD road freehub configurations.
