The Wahoo Kickr Core 2 is the entry into the world of Kickr trainers, whose common features are the external flywheel and the solid steel frame. The flywheel mass of the Core 2 is slightly smaller than that of the more expensive devices, but you don't notice much of this. The trainer reproduces the terrain of the virtual worlds effectively and smoothly.

The braking power is by far sufficient to stop even very strong riders. The fast-rotating flywheel mass shows no resonance in the test; the chain drive is the most audible feature.

At high power levels in ergometer mode, the Core 2 regulates more slowly than the top devices and the power also overshoots a little more; however, according to our measurements, the accuracy falls within the specified range of plus/minus two per cent. The device calibrates itself, spin-downs are no longer necessary.

Wahoo Kickr Core 2 - with Zwift-Cog

As standard, the Wahoo Kickr Core 2 is supplied with the Zwift cog, a single sprocket that is compatible with most derailleur gears. Gear changes in Zwift (and Rouvy) are made via additional controllers on the handlebars.

24 virtual gears cover a very wide range. The advantage is the fine gradation and compatibility with different bikes. The Zwift-Cog can be easily adjusted by hand in the chain line.

In addition to ANT+ and Bluetooth, the Core 2 also offers an Ethernet connection for races and Wi-Fi. The Core 2 is completely sufficient for most scenarios; compared to the best trainers, it is slightly less accurate, but otherwise there is nothing to complain about. However, it is a shame that there is still no handle on board.
