• Center lock mounting system realizes fast installation with a single lock ring, no extra screws needed, and the spline structure keeps the rotor firmly fixed on bike hubs during various rides.
• Special heat-dissipating tech lowers the rotor surface temperature during continuous braking, avoiding performance drop on long downhill sections and rough off-road terrain.
• 140mm and 160mm size options fit different road and mountain bike frame specs, adapting to both competitive riding and daily cycling setups with flexible matching.
• Hollow structural design enhances airflow around the rotor, accelerating heat dissipation and maintaining stable contact between the rotor and brake pads for consistent deceleration.
• Lightweight construction cuts down rotational weight of the bike, supporting responsive handling and smooth acceleration on flat roads, uphill climbs and winding trails.
