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 Ryan Williams

Very strong, excellent stopping power, fits perfectly without effort, everything you need to replace old pads is included in the kit. Loud when wet but retains stopping power, which is what you need for mountain biking. If you don't like noise, get organic pads, but be prepared to replace the pads twice a year or even more often (depending on usage). Organic pads are quiet but lack the stopping power of metal pads.
