XDS-A riders confirmed to be using Magene head units, possibly other stuff. I’d trust a Magene head unit, power meter, heart rate strap, and speed sensor at the WT level. This technology has been around for 15+ years now it’s not rocket science to get decent sensors made, I think it’s about time a Chinese electronics company got into the WT as a supplier. I’ve had good and bad experiences with Magene but it’s clear they are a big operation an can handle the demands
