Wahoo just dropped KICKR CORE 2, an updated version of their popular CORE. Let’s explore what’s new and determine whether you should upgrade.
KEY TAKEAWAY
The main difference between KICKR CORE and CORE 2 is that CORE 2 offers Wi-Fi connectivity, Race Mode, and sensor bridging. It also has redesigned legs and new LEDs that provide visual cues indicating connection status. Other features, such as the maximum resistance, gradient simulation, or accuracy, remained the same.

Wahoo KICKR CORE vs. CORE 2: What’s New?
While the CORE and CORE 2 share identical core performance specs, such as maximum resistance, gradient simulation, and power accuracy, the CORE 2 introduces several improvements that you appreciate, especially if you want to race indoors. It adds Wi-Fi connectivity, Race Mode, and integrated sensor bridging for streamlined device pairing. The setup is also simplified thanks to redesigned flat legs that improve stability, and the multi-color LEDs now offer clear visual feedback on connection status. Below is a detailed comparison of the two models.

Wi-Fi Connectivity
The KICKR CORE 2 now includes built-in Wi-Fi, delivering faster and more reliable connections compared to Bluetooth or ANT+. This upgrade enables seamless, automatic firmware updates and significantly improved data transmission (over 65% quicker on-screen stats), leading to a smoother, interruption-free riding experience. This is a feature that boiled down from the KICKR v6 into this lower-end model.
Race Mode
With Wi-Fi enabled, the new Race Mode boosts power data transmission to up to 10 Hz, a tenfold increase over the original CORE. This means your avatar will respond almost instantly to your efforts, and you will also have more up-to-date data. This is particularly beneficial during sprints, climbs, and rapid terrain changes, as well as when racing on Zwift and other indoor cycling apps.
Sensor Bridging (KICKR Bridge)
The KICKR CORE 2 introduces KICKR Bridge, a built-in sensor “bridge” that simplifies how your fitness devices connect. Rather than pairing your heart rate monitor, cadence sensor, or other peripherals separately, you can now link them directly to the trainer. From there, the KICKR CORE 2 streams all data through a single, consolidated connection. This is ideal for Apple TV users because of the limited number of Bluetooth connections. This feature also reduces pairing headaches and ensures smoother, more reliable data transmission during your workouts.

Updated LED System
The CORE 2 introduces vibrant, multi-color LEDs that provide clear, real-time visual feedback. They indicate power, connectivity (Bluetooth, ANT+, Wi-Fi), firmware status, and readiness to ride—so you always know the unit’s status at a glance.
Redesigned Legs for Improved Stability
Setting up the CORE 2 is easier and more foolproof thanks to its flat, color-coded legs with offset bolt holes. They install in the correct orientation, snapping into place quickly and securely. This design not only streamlines assembly but also ensures greater stability. The trainer will now be a bit less wobbly. Unfortunately, the 3D-printed mounts for tennis balls that many of you have to simulate a rocker plate will need a redesign.
Summary
The Wahoo KICKR CORE 2 is a worthwhile upgrade for newcomers or those frustrated by Bluetooth dropouts and complex sensor pairing. Thanks to its new Wi-Fi, Race Mode, and seamless sensor bridging, you will enjoy a more seamless experience.
If you already own the original CORE and are happy with your setup, upgrading is less essential, as core ride quality and accuracy haven’t changed. The CORE 2 is best for riders who want hassle-free connectivity, instant race response, and a trainer that won’t break their bank.
