This one leans more toward backend fixes, but still delivers some handy improvements for cyclists, map users and those relying on push notifications. The biggest addition is for indoor cyclists who pair the T-Rex 3 with accessories. Once connected to a speed sensor, power meter or cadence sensor, the watch will now generate real-time workout charts from those data streams.
