That's a pretty brief overview of the many different properties of brake pads. Also Tarty only sell 3 types of disc brakes, its hardly a cornerstone of their buisness. Neither is it in their interest to complicate consumers choice by fully explaining all the pros and cons of every product they sell! Oh right, I didn't realise your word was gospel! I will ask again, based on what evidence? Either way organic pads will surely work fine, some companies organic pads can work really well. In particular Avid and Magura organics are good and still have decent bite. Sintered pads sometimes don't work as well if it gets really cold, but in my experience in the majority of cases they give better bite and more powerful braking. This is based on test riding hundreds of bikes with dozens of different pad and brake combinations.
