Frequently Asked Questions
What is the difference?
The trainer is identical. The difference is the drivetrain setup supplied with the trainer.
Do I need another cassette?
The cassette version includes an 11-speed cassette. Riders using 8, 9, 10 or 12-speed bikes should purchase the correct cassette separately.
Can I use the Zwift Cog outside Zwift?
Yes. ERG workouts work across most training apps. Virtual shifting during free rides depends on software support.
