Built for dependable stopping power in every condition, the Shimano SM-RT30 Center Lock Disc Brake Rotor is a benchmark in durability, precision, and ease of installation. Whether you're riding across muddy trails, city streets, or alpine descents, this rotor delivers consistent braking performance you can rely on — with the trusted engineering that defines Shimano.
🚴♂️ Unshakeable Braking Confidence, Ride After Ride
From high-speed road rides to rugged off-road terrain, braking reliability is non-negotiable. The SM-RT30 is designed for riders who demand fade-resistant, modulated, and confident stopping in all environments. With Shimano’s refined rotor design, braking feels sharp yet controlled, with excellent heat dissipation and minimal noise.
Available in three sizes — 203mm, 180mm, and 160mm — this rotor series allows you to fine-tune your setup based on your riding style:
203mm: Maximum power for e-bikes, downhill, or aggressive MTB
180mm: Versatile, balanced braking across XC, trail, and enduro
160mm: Lightweight and responsive for road, gravel, or light MTB
🔧 Center Lock System: Innovation That Clicks
At the core of the SM-RT30’s efficiency is Shimano’s Center Lock system — a revolutionary mounting design that simplifies the traditionally tedious rotor installation process. Unlike 6-bolt alternatives, the Center Lock’s spline interface and lock ring mechanism allow you to install or remove the rotor in seconds, using a standard cassette lockring tool.
Benefits include:
Faster installation
More secure rotor fitment
Consistent rotor alignment
Reduced likelihood of loosening under torque
Whether you're in the workshop or trailside, the SM-RT30 offers worry-free serviceability.
🔩 Durable Construction, Shimano-Level Quality
The SM-RT30 is crafted with stainless steel braking surfaces that resist wear, heat, and corrosion, ensuring long-term performance with minimal rotor warp. Its design promotes even heat distribution, which reduces the chance of brake fade during extended descents or under repeated heavy braking.
Key characteristics include:
High rigidity for stable braking
Minimal noise and vibration
Precision-machined surface for pad compatibility
Compatible with both resin and metal pads
