Maguras perform tenfold better. The IBC's I had were very flexy and did a poor job of stopping the bike. Mushy mushy mushy. Lots of brake chatter too.uphiller said:Now that brings a smile to my face. I remember seeing ads for the IBC's once, and always wondered how they performed compared to the Maguras, from which they were obviously more or less copied. So... how do they work? What kind of pads do they use?
