There are some good announcers working the circuit these days, but the gold standard is still Jeff Roake who has suffered two strokes and is no longer able to announce races.
In his prime, he sounded like this.
Also note that that's a Huber Flyer that I describe in a recent book. He would attack at the bell, and no one could catch him. Great move if you're not blessed with a sprint.
By the way, he was in the drops.
