SPECIAL HEAT SINK

ZTTO cooling brake floating rotor increase special heat sink structure, after the heat treatment process, the heat sink is in seamless contact with the outer frame, which is equivalent to a thermal diffuser, heat can be quickly dissipated.

HIGH-STRENGTH MATERIAL- Compatible with Metal pad and Resin/Semi-metal pads

Rotor outer part use high-strength stainless steel material, inner part use 7075 ultralight thicken aluminum alloy material, full CNC engraving and milling, anodizing black and red color, laser marking, stamping.
FLOATING BUCKLE

75° five-pin fixed connection design, the most stable way to force, the floating structure can avoid the vibration caused by the longitudinal expansion of the disc when it brakes due to high temperature. Improve the safety of cycling.
ULTRALINGT

Made in hollow design, high-strength while reducing weight, and the hollow structure helps to dissipate heat, drain mud and drain.
