Wahoo Kickr Core 2 Direct Drive Turbo Trainer

Automatic calibration

The Core 2 calibrates itself as soon as you let your flywheel spin to a halt while cycling. So you will never have to worry about whether your trainer is properly calibrated again; it checks this itself, every single time.

Wi-Fi connectivity

As well as Bluetooth Smart and ANT+, you can also connect the Core 2 to your home network using Wi-Fi. This makes firmware updates easier and ensures a highly reliable connection while training.

Heavy flywheel

The flywheel simulates the inertia you feel outdoors, making acceleration and deceleration gradual rather than jerky. Thus, a virtual sprint feels just like one on the road.

How to assemble the Wahoo Kickr Core 2 turbo trainer in 4 steps:

You can set up the Core 2 yourself in about 15 to 20 minutes. All you need is the 6 mm Allen key supplied.

1. Unfold the legs: Place the trainer on a flat floor (and on a trainer mat), unfold the front and rear legs and secure them with the bolts supplied, tightening to 10 Nm.
2. Choose your adapter: Fit the quick-release or thru-axle adapter that matches your bike’s axle size to both sides of the trainer.
3. Place your bike on the trainer: Remove the bike's rear wheel, shift to the smallest front and rear cogs, and secure the bike to the trainer.
4. Connect to your app: Plug the power cable into the socket and search for the trainer using Bluetooth, ANT+ or Wi-Fi in Zwift or another training app.

If it is not going straightforward, consult the Wahoo User Manual, which also illustrates each step with photos.

• Let the flywheel spin down naturally from time to time while cycling; this allows the Core 2 to calibrate itself and ensures your power measurement remains accurate.
• Place a trainer mat under your turbo trainer to reduce vibrations and protect the floor.
• Open the Wahoo app regularly to see if a firmware update is available; you can install it in no time via Wi-Fi.
• Place a fan in front of your indoor trainer, especially during high-intensity sessions, so that you don't overheat.
