Review on Jagwire SRAM Disc Brake Pads: Sport Semi-Metallic, Pro Semi-Metallic, Pro Extreme Sintered, Sport Organic Options for AVID DB, Elixir, CR, CRMag, SRAM DB, Level T, TL, TLM B1, Ultimate B1 by Barry Hill

I had no problems with these pads; quiet, durable and minimal wear of the brake disc rotor. 2011 Giant Anthem X1 with Avid Elixir R brakes, 180mm IceTech front, 160mm IceTech rear. I have Jagwire pads on the rear and Koolstop Porcupads on the front. This combination withstands our very fast fire roads and steep 30% gradients, frantic corners and weirdly steep trails. I've tried several other pad and rotor combinations from Avid and Ashima, including Shimano XT's own brakes, and this setup matches, if not better than, the best of them all.
