About the H3 Plus (H3)
Company status: Saris filed Chapter 128 receivership in Wisconsin (July 2022) and was acquired by C+A Global; in Oct 2024 Saris cut trainer prices and said it planned to rebuild; a dealer reported in Feb 2025 that Saris trainers were no longer distributed via QBP in the US (DC Rainmaker, TrainerRoad forum). The original H3 URL redirects to saris.com home; the H3 Plus page (12-speed-compatible revision) shows 'Sold Out / Notify me'. H4 (announced Sept 2022: 2300 W, 25%, ±1%) has no live saris.com page found. Weight 47 lb is from the H3 search snippet of the same Saris page, not re-verified on the H3 Plus page.
