Hi all When I first installed zwift I had a wheel on trainer that was not listed in zwift. I now have a wheel on trainer that is listed in zwift. I can’t find where I can change my trainer in order to have a more accurate estimate of my power. Please help! ---

Hi @Harry_Lykidis Go to the paring screen and unpair the speed sensor. When you click search you Will get the option to select your trainer. [Pairing Your Speed Sensor — Official Instructions | Zwift - YouTube](https://youtu.be/_9d8R8JK2CQ) ---

Thank you very much for your quick response. This worked fine. It’s a shame that this info is not listed anywhere in the support page nor the FAQ page. It was very frustrating that I couldn’t find a solution on this on my own… ---

After I set my new trainer, I see that at power estimation mode there are two options. The one says classic and the other one is grayed and says zPower. Why is this greyed? ---

What kind of trainer did you get? zPower refers to a classic wheel on “dumb” trainer’s power curve that Zwift uses to estimate your power/watts. ---

Hi Mike are you riding and typing? LOL I think zpower is a classic trainer that send power data and a classic trainer use a speed sensor and zwift convert that to power. ---

Unfortunately I see that not all dumb trainers have the option of zpower but only a few… [https://support.zwift.com/en\_us/wheel-on-trainers-r1B5nQWxS](https://support.zwift.com/en_us/wheel-on-trainers-r1B5nQWxS) On the support page for zpower ( [zPower Setup](https://support.zwift.com/en_us/zpower-setup-r1XjaXbxr) ) it is nowhere to be found that only a few trainers support it… Pretty confusing “support” pages… Anyway, thank for all your answers. Hope smart trainers become “in stock” soon 🙂 ---
