160mm Stainless Steel Disc Brake Rotor (6-Bolt)

Key Features

• High-Grade SUS410 Stainless Steel: Manufactured from premium heat-treated stainless steel for excellent anti-corrosion properties and high-strength durability under heavy braking.
• Advanced Heat Dissipation: Features a specialized "skeleton" or ventilated pattern that increases surface area to quickly dissipate heat, preventing "brake fade" on long descents.
• Universal 6-Bolt Mounting: Engineered with a standard 44mm bolt circle diameter (BCD), making it compatible with the vast majority of mountain bike and road bike disc hubs.
• Precision Ground Surface: The friction surface is double-sided ground to a mirror-like finish to ensure immediate pad engagement, reduced noise, and a shorter "bed-in" period.
• Lightweight Wave Design: The outer wave edge helps shed mud, water, and debris quickly while reducing the overall rotating mass of the wheel.

Compatibility & Fitment

This rotor is a universal component compatible with most modern disc-brake-equipped bicycles. Key fitment details include:

• Bicycle Types: Mountain Bikes (MTB), Road Bikes, BMX, Gravel Bikes, and Electric Bikes (E-Bikes).
• Hub Compatibility: Fits all standard 6-bolt hubs. (Note: Not compatible with Shimano "Centerlock" hubs without an adapter).
• Brake Systems: Compatible with both Mechanical (cable) and Hydraulic disc brake calipers.
• Pad Compatibility: Works with Resin (Organic), Semi-Metallic, and Sintered (Metal) brake pads.

When to Replace

• Minimum Thickness Reached: Most rotors have a "Min. TH" (often 1.5mm) stamped on them. If the rotor is thinner than this, it is at risk of structural failure.
• Warping or Wobble: The rotor is physically bent and rubs against the brake pads during every wheel rotation, causing a "pinging" sound.
• Deep Scoring: Visible deep grooves or "lips" on the friction surface caused by worn-out brake pads (metal-on-metal contact).
• Discoloration: A dark purple or blue "burnt" tint on the metal, indicating the rotor has been severely overheated and has lost its tempering.
• Persistent Squealing: If cleaning the rotor with alcohol doesn't stop the noise, the metal may be glazed or contaminated with oil.

Installation Tips

• Clean the Surface: Before installation, wipe the entire rotor with 70% or higher Isopropyl Alcohol to remove the factory protective oil film. Do not touch the friction surface with bare fingers after cleaning.
• Bolt Tightening Pattern: To prevent warping, tighten the 6 bolts in a "star" pattern (1-4-2-5-3-6). Do not tighten them in a circular sequence.
• Torque Specs: Most rotor bolts require a specific torque (typically 4–6 Nm). Over-tightening can strip the hub threads or snap the bolts.
• Thread Locker: Ensure the included bolts have pre-applied blue thread-locker (Loctite), or apply a small drop yourself to prevent the bolts from vibrating loose.
• Bed-In Procedure: After installation, perform 10–15 controlled stops from moderate speed to "marry" the brake pad material to the rotor surface for maximum stopping power.
