The Shimano XT SM-RT86 Rotor delivers powerful, consistent braking for mountain biking across all terrains. This 203mm 6-bolt rotor features Ice-Tech technology for superior heat dissipation, improving performance on long descents. Ideal for aggressive trail, enduro, and downhill riders.

Product Specifications:

• Rotor Size: 203mm
• Mount Type: 6-bolt
• Brake Compatibility: Shimano hydraulic disc brakes
• Material: Stainless steel rotor with aluminum core
• Technology: Ice-Tech heat-dissipating design
• Color: One Color (Silver/Black)

Key Features:

Ice-Tech Cooling Technology: Features a stainless steel-aluminum-stainless steel sandwich structure that reduces heat buildup and brake fade on long descents.

Powerful 203mm Size: The larger diameter increases braking leverage, making it ideal for enduro, downhill, or e-MTB setups needing maximum stopping power.

6-Bolt Mounting: Standard 6-bolt interface ensures broad compatibility with most MTB hubs and easy installation.

Warp-Resistant Structure: Multi-layer design resists warping under high heat, maintaining consistent rotor shape and braking feel.

Shimano Trusted Performance: Designed to match Shimano XT brake systems for optimal modulation, control, and reliability in demanding conditions.

How it works:

The Shimano XT SM-RT86 rotor uses Ice-Tech technology to improve heat management through a layered construction of stainless steel and an aluminum core. As braking generates friction, the aluminum layer dissipates heat faster than steel alone, preventing fade and improving consistency. The 203mm diameter increases braking force, especially during aggressive riding or on steep terrain. The 6-bolt mount fits most MTB hubs, and installation is quick with standard rotor bolts.

FAQs:

Can this rotor be used with non-Shimano brake calipers?

Yes, it can work with other brands’ calipers, but it's optimized for use with Shimano hydraulic disc brakes.

Does the rotor come with mounting bolts?

No, mounting bolts are typically not included and must be purchased separately or reused from your current setup.

Is this rotor suitable for e-MTBs?

Yes, the 203mm size and heat management features make it a strong choice for heavier e-MTBs requiring more braking power.

How often should I replace the rotor?

Replace the rotor when the thickness drops below the manufacturer's minimum spec (usually around 1.5mm) or if it's warped or heavily scored.
