Why Choose KICKR CORE 2

This trainer represents the perfect balance of value and performance. The original CORE earned a reputation for reliability and quiet operation—CORE 2 keeps that proven foundation while adding the features serious cyclists demand.

Race Mode delivers competitive responsiveness you'd expect from premium trainers, while integrated WiFi ensures seamless connectivity and automatic updates. The simplified setup means you're training faster, not wrestling with assembly. The 1800-watt power output handles everything from recovery sessions to maximum efforts.

For cyclists transitioning to smart training, CORE 2 provides an affordable entry point without sacrificing the accuracy, responsiveness, and ecosystem compatibility that make training indoors effective.

Getting Started

1. Assembly (15-20 minutes):
Unbox and follow the color-coded leg assembly. The guided setup in the Wahoo App walks you through installation step-by-step.

2. Connect:
Plug in the AC adapter and pair to the Wahoo App via WiFi (automatic) or Bluetooth.

3. Mount Your Bike:
Use the included adapters for your hub type (QR or thru-axle). Secure your bike in minutes.

4. Calibrate:
Perform a simple spin-down calibration for power accuracy. Takes 60 seconds.

5. Train:
Launch your first workout through the Wahoo App, Zwift, or compatible platform.

Race Mode – The Competitive Advantage

Traditional smart trainers update power data once per second, averaging wattage across the entire rotation. In racing scenarios, this misses critical power spikes during attacks and sprints.

Race Mode changes this entirely. The 10 Hz update rate captures power with every flywheel revolution. The result:

• Faster Responsiveness: Immediate feedback to power changes
• Accurate Drafting: Know exactly when the virtual pace changes
• Competitive Timing: Land attacks and sprints with precision
• Pro-Level Feel: Experience racing like the pros

Available exclusively with WiFi connection, Race Mode brings premium-trainer responsiveness to an entry-level price point.
