About the Tacx FLUX 2 Smart
Garmin still lists FLUX 2 Smart on regional product pages and it is sold by US retailers (REI) as of late 2026, though stock is inconsistent. No official successor announced; Garmin's blog lineup (2026) still shows NEO 3M, NEO 2T, FLUX 2, FLUX S. The 2020 revision (sometimes called Flux 2.1) is the version currently sold. No WiFi, no descent simulation.
