About the Zwift Hub (Classic / Hub One)
Zwift discontinued both Zwift Hub Classic and Hub One on 7 Feb 2024 (DC Rainmaker), four months after Hub One launched, and committed to two years of firmware updates. The Zwift Cog & Click concept continued on Wahoo's KICKR CORE. Zwift Hub was a rebadged JetBlack Volt.
