FAQ

What is the main difference between the CORE 2 and the KICKR?

The KICKR has higher power output (2,200W vs 1,800W), better power accuracy (+/- 1% vs +/- 2%), greater grade simulation (20% vs 16%), AXIS Action Feet for lateral movement, and WiFi. The CORE 2 is the more accessible direct-drive option that covers most riders' needs without those extras.

Do I need to buy a cassette separately?

Yes. Direct-drive trainers like the CORE 2 require a cassette to mount your bike. The cassette is sold separately. If you are unsure which cassette you need to match your drivetrain, reach out before ordering.

Is +/- 2% power accuracy good enough for serious training?

Yes. For zone-based training, interval work, and most structured plans, +/- 2% is more than adequate. The primary use case where +/- 1% matters is comparing outdoor and indoor power data directly or racing virtually where every watt counts.

Best For

Cyclists entering the direct-drive smart trainer category who want reliable power data, quiet operation, and compatibility with all major training platforms at a more accessible price than the KICKR.
