I need new brakes for my 7120 brakes. I figured OEM is usually best, but I cannot find any OEM pads. I called bike shops and looked online. There are some with no box from china on ebay, but I'm worried they will be fake. Are there any decent aftermarket pads that I should consider? I'm leaning more towards metallic for more bite being that I'm 240 lbs and ride pretty intense downhill stuff from time to time. Any input is appreciated.
