Key Features
- Martensitic Stainless Steel (1CR13): Corrosion-resistant and built to last — resists rust even in wet, muddy riding conditions.
- CNC Precision Machining: Smooth, high-precision surface finish ensures quiet, vibration-free braking with no abnormal noise.
- Hollow Porous Design: Strategic cutouts reduce rotational weight while maximizing airflow for outstanding heat dissipation during extended descents.
- Color Paint Spraying Process: Available in Black, Red, Blue, Green, and Purple — high-precision polishing for a premium finish that lasts.
- Standard 6-Hole Mounting: Compatible with all standard 6-bolt hydraulic and mechanical disc brake systems on MTB and road bicycles.
- Multiple Size Options: Choose 160mm or 180mm diameter (diagonal bolt hole distance: 44mm); thickness approx. 1.9mm.

Frequently Asked Questions
Q: Is this disc brake rotor compatible with hydraulic brake systems?
A: Yes — this 6-bolt disc brake rotor is compatible with both hydraulic and mechanical disc brake systems that use a standard 6-bolt (IS) mounting interface. Always verify your brake caliper's bolt pattern before purchasing.
Q: What is the difference between the 160mm and 180mm rotor sizes?
A: The 180mm rotor provides a larger braking surface, which improves heat dissipation and braking force — ideal for heavier riders, technical descents, or loaded touring. The 160mm rotor is lighter and well-suited for cross-country riding and general road use where maximum stopping power is less critical.
Q: Will this rotor rust over time?
A: The rotor is made from 1CR13 Martensitic Stainless Steel, which is naturally corrosion-resistant and highly resistant to rust, making it suitable for all-weather riding conditions including wet and muddy trails.
Q: Does this rotor fit both mountain bikes and road bikes?
A: Yes. This rotor is designed for use on both mountain bikes (MTB) and road bicycles, as long as the bike's hub features a standard 6-bolt disc mounting interface with a 44mm diagonal bolt hole spacing.
