1. Accurately fit mainstream models, zero error installation. 2. Strictly match MT200/M285/M375/M515 and other 10 models, slot and spring pad 1:1 original moulding, 3 minutes selfservice installation, no need to debug and ready to use, eliminate brake rattles and scuffing discs! 3. Resinmetalceramic triple composite, allterrain and allweather braking. 4. Innovation 40% Resin 50% Metal 10% Ceramic Formulation: low temperature resin for fast response, metal particles to enhance heat resistance, ceramic layer for rain battle antislip. 5. Muffling grooves antiflutter springs, silent braking without disturbing the public 6. Exclusive cross sound cancelling groove to ease airflow and eliminate frequency whistling; hardened stainless steel spring plate to suppress vibration, from city commuting to mountain descending, the whole process of braking is silent and squeak. 7. Resistant to temperature and abrasion, 1 pair 2 times the life span of normal blades. 8. The ceramic layer is resistant to temperature of 650℃ downhill, and the metal substrate is resistant to gravel scratching. Measured 3000km mixed road conditions wear only 0.8mm (ordinary film ≥ 1.5mm), commuters half a year without replacement. 9. Safety and environmental protection
