How to choose bicycle disc brake pads?
In my opinion you should run metallic pads if:
-You are heavy
-You ride downhill
-The conditions are wet, muddy, etc.
and run resin pads or semi metallic pads if:
-you are light
-Conditions are dry
-You like lots of initial grab
-Your riding is less hard on brakes i.e. dirt jump/street, XC, etc.
Although I have now recommended pads for you to use, you have to make your own choices on pads according to your riding, the above list should be considered to be a guideline, and not used as a strict rule.
