Jamie McLoughlinwrote a review of Shimano J02A Resin Disc Brake Pad on April 12, 2019
Familiarity: I've put it through the wringer
Having run both Shimano metallic and resin pads, I prefer the resin pads. Lever feel between the two is similar, with a bit more modulation to be found with the resin pads. For lift served, repeated long descents look to the metallic pads. For more pedal powered riding these pads do a great job with the added benefit of being quieter, and providing a touch more modulation.
