This SRAM flat mount disc brake adapter is used to correctly position a flat mount caliper for either a 140mm or 160mm rotor. It’s a simple, frame-specific solution that keeps caliper alignment correct without extra spacers or guesswork.
The same adapter works for both rotor sizes—just rotate it 180 degrees to switch between 140mm and 160mm setups.
Key Features
• Single adapter supports both 140mm and 160mm rotors
• Reversible design for easy size change
• Flat mount to flat mount interface
• Stainless steel mounting hardware included
• Clean, low-profile installation
Compatibility & Use Notes
• Rotor size compatibility: 140mm or 160mm
• Frame mount: Flat Mount
• Caliper mount: Flat Mount
• Adapter size: 0mm / 20mm (depending on orientation)
• Designed for front brake applications
• Not compatible with post-mount frames or calipers
• Rotor size must match adapter orientation
Service / Ownership Context
Adapter orientation matters—installing it incorrectly will cause caliper misalignment and rotor rub. Always confirm rotor size before mounting and torque hardware evenly. After installation, center the caliper and check pad clearance before riding.
Fit & Use Signals
• You’re running a flat mount frame and flat mount caliper
• You’re using a 140mm or 160mm front rotor
• You want a clean, reversible adapter solution
• Not a fit for post-mount frames or calipers
• Not a fit for rotor sizes other than 140mm or 160mm
