2 Pairs Bicycle Disc Brake Pads for Sram Guide RSC Avid XO Elixir 7 9 Trail 4 Piston MTB Disc Brakes (Resin,Semi-Metallic,Sintered Metal)

First of all these pads have thicker bedding material than the standard SRAM pads. A lot thicker: so much so that you’ll probably have zero play left in your brakes and you might even have to bleed a little fluid. I have Guide R brakes, 2018 model. Stopping power is as good as OEM. They make more noise and squeak compared to OEM, and have lower life than OEM.Major downside: they will blacken your rotors. The SRAM pads leave your rotors clean and shiny, but these pads have made my rotors look like I rubbed a bit of tar onto the rotor surface. It doesn’t affect braking, so it seems to be just cosmetic so far.I’ll update this review over time. The price was certainly right, so that’s a plus!UPDATE: I contacted the manufacturer about the staining of the rotors and they said they’re reformulating the pad compound to fix the issue.I’ve done a number of really aggressive rides with these pads and they work really well – excellent stopping power and no fade that I could tell. They’re noisier than the SRAM pads when they get really hot, but they still stop really well.UPDATE 2: I have removed these pads and gone back to the SRAM sintered, after using sandpaper and Windex to clean all the black residue from these pads off the rotors. I will keep them as spares only. [...]
