Cartridge failed after minimal use
Bought in July 2022, rode on it for a season and a half, and brought it out this year to discover that the cartridge failed. Now doesn’t hold any weight. I’m 6’4, 210lbs, and ride pretty moderately. I wouldn’t have thought the 25-30 rides I took it on would be enough wear and tear for this product to fail. Was told by RaceFace that their warranty doesn’t apply to dropper posts. This seems more like a mechanical failure and not a wear and tear issue. Have reached out to RaceFace to see if they’ll replace or repair at no charge or discounted fee, and will update this review accordingly if they can work with me. Worked well until the cartridge failure!
