Can I use a bike built with RED or Force eTap AXS™ on my direct drive 11-speed trainer?

Direct drive trainers require XDR cassette compatibility in order to use them with a RED eTap AXS™ bike. Use of 12-speed RED chains on 11-speed cassettes is not recommended, due to incompatibility that can damage the drivetrain. SRAM has provided information to market leading direct drive trainer companies covering what’s required for compatibility with RED or Force eTap AXS™ drivetrains. Please check with your preferred trainer brand for compatibility.
