Why Choose This Disc Brake Rotor?

• 2.3mm Thick Steel Construction – Extra thickness compared to standard rotors means greater durability and reduced warping under extended braking.
• Advanced Heat Dissipation Design – Strategically cut ventilation slots and a lightweight open pattern channel heat away quickly, keeping your braking performance stable even on long descents.
• Universal 6-Bolt Mounting – Compatible with virtually all standard 6-bolt disc brake hubs, making installation straightforward and tool-free beyond basic hex keys.
• 5 Size Options – Choose from 140mm, 160mm, 180mm, 203mm, or 220mm to match your specific fork/frame clearance and braking preference.
• E-Bike Ready – Built to handle the higher speeds and increased momentum of electric bikes without compromising performance.
• Precision Machined Surface – Smooth, flat braking surface ensures even pad contact and consistent modulation right out of the box.

Frequently Asked Questions

Q: What bike types is this 6-bolt disc brake rotor compatible with?

A: This disc brake rotor is compatible with any bicycle that uses a standard 6-bolt (IS) disc brake hub, including e-bikes, electric mountain bikes, conventional mountain bikes, gravel bikes, and commuter bikes. Both mechanical and hydraulic disc brake calipers are supported.

Q: Which size disc brake rotor should I choose for my e-bike?

A: For most e-bike commuting and trail riding, a 180mm or 203mm rotor is recommended for stronger braking leverage at higher speeds. If your fork or frame has limited clearance, or you ride lighter terrain, 140mm or 160mm are excellent choices. The 220mm option suits aggressive downhill or high-speed e-bike use. Always check your frame's maximum rotor size specification before ordering.

Q: Is the 2.3mm thickness compatible with standard brake calipers?

A: Yes. While many stock rotors are 1.8mm–2.0mm, the 2.3mm thickness is designed to work with most standard disc brake calipers. The extra thickness improves heat resistance and longevity. If you have very narrow caliper spacing, check your caliper's minimum/maximum rotor thickness specification to confirm fitment.

Q: How do I install this 6-bolt brake rotor?

A: Installation is straightforward. Align the rotor over the six bolt holes on your hub flange, insert the six T25 Torx bolts (not included), and tighten in a star pattern to your manufacturer's specified torque (typically 2–4 Nm). Re-bed your brake pads after installation by performing several moderate stops to seat the new rotor surface.
