DURA-ACE/XTR RT-CL900 Rotor
$124.99
Regular price
The Shimano DURA-ACE/XTR RT-CL900 is an Ice Tech Freeza Center Lock disc rotor built for consistent braking performance across road and mountain applications. Its three-layer steel and aluminum sandwich construction manages heat generated under braking, helping control rotor temperature during extended descents.
The clad steel-aluminum-steel design lets heat radiate quickly through the aluminum core, lowering surface temperature by roughly 50 degrees during use. Paired with Ice Tech pads, surface temperatures can drop from around 400 to 300 degrees, supporting stable braking feel across repeated stops.
