Wahoo KICKR CORE 2 Trainer

Wahoo KICKR CORE 2 – smart cycling trainer with 11-speed cassette

Wahoo KICKR CORE 2 is a smart direct-drive cycling trainer designed for quiet, realistic and data-driven indoor training. Automatic resistance adjustment, precise power measurement and a stable construction enable quality interval training, virtual rides and online races all year round.

The trainer comes with a pre-installed 11-speed cassette with an 11–28 range, so it's quickly ready for use with a compatible 11-speed road bike. Shifting is done via the bike's regular shift levers, keeping a natural and familiar riding feel.

Realistic riding feel

KICKR CORE 2 uses electromagnetic resistance and a flywheel that create a smooth and consistent load. When connected to a compatible training app, it automatically adjusts resistance to the gradient of the virtual route – pedalling becomes harder uphill and easier downhill.

Gradient simulation up to 16 percent and maximum resistance of 1,800 W allow for demanding climbs, sprints and intense intervals. The belt drive ensures quiet operation, making the trainer suitable for training in an apartment or early in the morning.

Precise data for more effective training

The built-in power meter tracks power, speed, distance and cadence. Power measurement accuracy of approximately ±2 percent enables reliable progress tracking, intensity setting and comparison of results between individual workouts.

During structured workouts, ERG mode can automatically maintain the required power. The trainer continuously adjusts resistance, allowing the cyclist to focus on proper cadence, technique and execution of each interval.

Fast and stable connectivity

Built-in Wi‑Fi connectivity enables more stable communication with training apps and automatic installation of software updates. Bluetooth, ANT+ and ANT+ FE-C connections are also available, allowing connection with phones, tablets, computers and compatible bike computers.

The KICKR Bridge feature can relay data from compatible sensors, such as a heart rate monitor, to the training app through the trainer. This reduces the number of direct connections and helps prevent issues on devices with a limited number of Bluetooth channels.

More responsive virtual racing

Race Mode enables faster transmission of power data, so the virtual cyclist follows pace changes more directly. This is especially useful during sprints, attacks, drafting and closing gaps in online races.

The trainer is compatible with popular platforms such as Zwift, ROUVY, TrainingPeaks Virtual, MyWhoosh and Kinomap, so you can adapt your training mode to your goals and preferences.

Stable and durable construction

Redesigned legs simplify assembly and provide a stable base during out-of-saddle riding and powerful sprints. Multi-colour LED lights clearly indicate the operating status and active connections, making system setup clearer.

KICKR CORE 2 is also compatible with the Wahoo KICKR CLIMB and KICKR HEADWIND accessories. You can upgrade your home training setup with physical gradient simulation and a smart fan that adjusts airflow speed to match training intensity.

Drivetrain compatibility

KICKR CORE 2 also allows the use of other compatible cassettes, but a different number of gears or SRAM XD/XDR, Campagnolo or Shimano CUES/LinkGlide systems may require replacing the cassette, spacer or freehub body.

The included adapters allow use with most bikes with 130/135 mm quick releases and 12 × 142 and 12 × 148 mm thru axles. Before purchasing, we recommend checking the compatibility of your bike's frame, axle and drivetrain.
