Original Full Metal Pads-same as XT pads
There are many benefits of full metal pads, greater braking force, stronger heat resistance, stable braking force regardless of sunny or rainy days,But because it is harder, it takes a period of running-in before it can work normally. At the beginning, the braking force is small which is normal, it will get bigger and bigger. And a slight braking sound is normal for metal pads.
Fit for 51 mm IS ＆ 74mm post mounting
ZTTO Cylinder Ratio and Brake Linearity
The brake equired strength is small, in the long downhill, fingers and arms are not easy to feel tired.Brake performance is not affected by weather changes, still stable, not easy to be affected by soil or rain.
