Shimano RT-MT800-SS Rotor - 140mm | Center Lock
What Is the Shimano RT-MT800-SS and Who Is It For?
The RT-MT800-SS is Shimano's stainless steel variant of the XT-grade RT-MT800 center-lock disc rotor, offered in 140mm for applications where a lightweight, smaller-diameter rotor is the correct specification. Unlike the standard RT-MT800, the SS version uses a single-material stainless steel construction throughout rather than the aluminum-core Ice Technologies layered design. This makes the SS variant lighter than the full Ice Technologies rotor at the cost of reduced heat dissipation capacity, which is an appropriate trade-off for XC racing and lighter trail use where sustained descents and repeated heavy braking are not the norm. The 140mm size further reduces rotational weight and is the standard rear rotor size for XC racing setups.
The center-lock interface requires a center-lock compatible hub and installs using a standard cassette lockring tool. The RT-MT800-SS is compatible with Shimano XT, XTR, SLX, and Deore hydraulic disc brake systems and any hydraulic caliper accepting 140mm rotors with the appropriate adapter. For XC racers and weight-conscious riders running center-lock hubs who want an XT-grade stainless rotor at the smallest standard MTB disc size, the RT-MT800-SS 140mm delivers the correct balance of stopping power and weight without the additional heat management hardware of the full Ice Technologies construction.
