The union of Wahoo and Zwift results, with the invention of the Zwift Cog, in a very useful cassette.

In each house the problem is different, but they all start the same: assembling and disassembling the cassette of a bicycle trainer. If a couple shares the roller, they must do so. If a cyclist trains with several bikes, he must do so. And if that same cyclist only has one bicycle and wants to use it inside and outside the home, he must do so. With practice, this assembly process can be simple, but it is undoubtedly annoying - and greasy -. Therefore, finally, the union of Wahoo with Zwift proposes a solution: the Cog, a 'magical' cassette, unique, very fast and compatible with almost all bicycles. Get home, remove the rear wheel and place the bike on the roller.

Other smart trainers require their own mechanism to do so, this Wahoo Kickr Core Zwift One already has that adaptation to the 'game' in its genes. With the bicycle connected to the Cog, the resistance changes according to the route we take on the screen of our television, our computer or our phone and for the rest, there is the Click.

The Click is a small control that can be placed anywhere on the handlebar and acts as a chainring and sprocket changer. The speed of the changes and their simplicity are surprising.

Although it does not use its own cassette, the Cog is really quiet. With the chain properly aligned, there is no noise other than the transmission, always an important fact in indoor cycling.

Among its specifications, its Bluetooth and ANT+ connectivity with sensors, heart rate monitors and devices.

For 649.99 euros with the Cog and Click included, the Wahoo Kickr Core Zwift One is possibly the tightest virtual cycling trainer on the market, as it includes a one-year subscription valued at 199 euros.
