Shimano 105 RT-CL700

Ice Technologies Heat Control. Silent Operation.

The engineering peak of the Shimano RT-CL700 is its proven Ice Technologies 3-layer sandwich construction. By fusing a lightweight aluminum core between two stainless steel outer braking surfaces, the rotor sheds heat rapidly across its surface. Combined with a rigid alloy carrier design, the RT-CL700 minimizes lateral thermal expansion, preserving consistent lever feel and predictable modulation under heavy braking.

Why the Shimano RT-CL700 Delivers Superior Braking:

• Ice Tech 3-Layer Sandwich Construction: Aluminum core clad in stainless steel dissipates heat rapidly, lowering surface temperatures to prevent brake fade and extend pad life.

• Quiet, Flex-Resistant Carrier: Redesigned 3D alloy spider arm structure prevents rotor warping and flex during intense thermal buildup, eliminating pad rub and screeching.

• Consistent Brake Modulation: Smooth, predictable stopping power under dry or wet conditions, giving you complete cornering confidence on steep mountain descents.

• Centerlock Mounting System: Precision spline mount with locking ring makes installation, removal, and alignment fast, secure, and straightforward.

• Resin & Metal Pad Compatible: Versatile braking surface works seamlessly with both resin (organic) and metallic brake pad compounds.

The Alegro Perspective: Rotor rub after a long, hard descent is one of the most frequent rider complaints we solve. Older rotors warp slightly when hot, causing that frustrating "tchk-tchk-tchk" noise against the brake pads until they cool down. The RT-CL700's reinforced carrier structure completely fixes that issue. It remains dead-flat under heavy heat loads, keeping your brakes silent and your lever feel crisp from the top of the pass to the bottom.
