Material Excellence & Exquisite Finish
Chaser Sports constructs these covers from premium 7075-T6 aluminium to handle the substantial torque vectors required to secure disc rotors safely. The manufacturing incorporates a specialised CNC polishing process alongside oxidation colouring. This method ensures maximum structural durability under a 35–40Nm load while generating an exceptionally bright, high-gloss aesthetic to match your hub, frame, or valve accents.
Twin Fitting Configurations & Tool Guide
To provide complete frame, axle, and fork clearance compatibility, Chaser offers two distinct structural variants:
-
Internal Splines: Shaving weight down to an incredible 4.7g, this low-profile variant is ideal for standard quick-release or 12mm thru-axle setups. It is explicitly designed for installation using standard cassette/internal lockring tools such as the SuperB TB1010.
-
External Splines: Weighing just 5.5g, this external-notch variant provides the necessary clearance for thicker 15mm/20mm thru-axle hubs. It features a 16-notch external footprint designed to fit standard bottom bracket tools like the ParkTool 69.2 or SHIMANO FC36.
