SHIMANO STePS RT-EM900 Ice-Tech Centerlock brake disc features an integrated magnet for the use with the SM-DUE11 speed sensor (not included). Developed for rear wheel installation the corresponding standard front disc can be maintained. The manufacturer recommends the SM-RT99 disc (optional) as ideal counterpart. The RT-EM900 disc is designed for E-Bike use. Aluminium cooling fins reduce heat development and increase brake force as well as brake pad's lifetime. The sandwich structure (stainless steel - aluminium - stainless steel) offers also an effective heat management while braking what results in unparalleled braking performance and reliability in the most demanding conditions. Optional Ice-Tech brake pads with their own cooling fins can reduce the brake pad surface temperature further.

ICE TECHNOLOGIES and FREEZA - provide consistent braking performance with longer pad life, less brake fade and noise. The lightweight and highly efficient three-layer sandwich structure of stainless steelaluminumstainless steel enhances heat dissipation.
The CENTER LOCK system - makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
