The RT-MT800 brake rotor by Shimano stands for perfect heat dissipation

The Shimano RT-MT800 Internal Serration brake rotor uses Ice Technologies FREEZA heat dissipation to further reduce temperatures, resulting in more consistent braking performance. The life of the brake pads is also extended. The RT-MT800's proven sandwich construction with an aluminium core between two layers of stainless steel ensures efficient heat dissipation via the integrated radiation fins.

- great heat dissipation due to innovative design
- reduced fading
- easy installation with Spline Mount and lockring
- version with internal toothing
- painted spider, polished rotor, anodised lockring

Note: For 15 mm and 20 mm front thru axle hubs, the SM-HB20 lockring must be used.


Ice Tech FREEZA brake rotors show even less fading due to 40° C less heat development compared to SM-RT98. The three-layer sandwich construction consists of stainless steel flanks and an aluminium core with integrated cooling fins. The two-part structure with the aluminium spider dissipates the heat well. The dirt-repellent design extends the service life of the rotor and pads. A real eye-catcher is the sporty, aggressive high-tech design.

Sehr gute Bremsscheibe. Zusammen mit G03A Belägen lautloses Bremsen. Leichter und Optisch schöner als die DuraAce Scheibe.

Top Bremsscheibe. Gleiches Gewicht wie die XTR Scheibe, aber leichter als die Dura-Ace Scheiben. Verziehen sich ein bisschen wenn sie warm werden, aber noch im Rahmen
