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

First, these pads have a thicker backing material than standard SRAM pads. Much thicker: so much so that you'll likely run out of brake play and might even need to pump some fluid. I have Guide R brakes, 2018 model. Braking performance is the same as OEM. They make more noise and squeaks than OEM and have a shorter lifespan than OEM. The main disadvantage: you will blacken your rotors. SRAM pads leave your rotors clean and shiny, but these pads make my rotors look like I've rubbed some resin onto the surface of the rotor. It doesn't affect braking, so it appears to be cosmetic for now. I will update this review over time. The price was definitely right, so that's a plus! UPDATE: I contacted the manufacturer to paint the rotors and they said they would reformulate the pad formulation to fix this issue. I've had some really aggressive rides with these pads and they work really well - great stopping power and no fade as far as I can tell. They're noisier than SRAM pads when hot, but they still hold up really well. UPDATE 2: I removed these pads and reverted to sintered SRAM after using sandpaper and Windex to remove any black residue from them. rotor linings. I keep them as a reserve.
