I own TRP Spires, TRP HY/RD and TRP Spyke disk brakes and an assortment of disk brake pads in organic, semi metallic and sintered. These were all failures. The Kool Stop sintered pads that came with the Paul Klampers work better than the EBC gold I tried. They don't glaze and they slow really well. I was ready to have cantilever studs welded on my bicycle frame and put Magura hs-33s on it so I could stop. The Paul setup is not flimsy like most or all of the other mechanical disk brakes on the market.
