FSA Afterburner One-Piece Disc Brake Rotor – 180mm – 6-Bolt

The FSA Afterburner is a one-piece steel disc rotor designed to balance braking power, heat management, and weight. It uses added material where it matters for cooling and stiffness, while removing excess material to keep weight down.

At 180mm, it’s a versatile rotor size for trail, gravel, commuting, and e-bike setups that want stronger braking than 160mm without stepping up to oversized rotors.

Key Features
• One-piece steel construction
• Strategic material placement to improve cooling
• Drilled rotor surface to reduce weight and manage heat
• Consistent braking feel under load
• Lightweight design for its size

Compatibility & Use Notes
• Rotor size: 180mm
• Mount type: 6-bolt (ISO)
• Weight: 143g
• Compatible with 6-bolt hubs only
• Requires correct caliper adapter for 180mm rotors
• Not compatible with Centerlock hubs
• Frame and fork must be rated for 180mm rotor use

Service / Ownership Context
When changing rotor size, confirm you’re using the correct caliper adapter and that your frame or fork allows a 180mm rotor. Install bolts in a star pattern and torque evenly. Bed in the rotor with new or properly prepared pads for best braking performance and noise control.

Fit & Use Signals
• You want improved braking and heat control over a 160mm rotor
• You ride trail, gravel, commuting, or e-bike setups
• You prefer a lightweight one-piece steel rotor
• Not a fit if your frame or fork can’t clear a 180mm rotor
• Not a fit for Centerlock hub systems
