The win gives Dowsett his fourth title in five years, having lost out to Sir Bradley Wiggins in 2014, and moves him above the former Team Sky rider and Michael Hutchinson in the all-time list.
Twenty-six-year-old Dowsett joins Dangerfield on four wins, with the latter's last title coming in 2005, and tops an impressive year for the Essex-born rider.
Not only did he break the UCI Hour Record back in May, but he later won his first stage race - Bayern Rundfahrt - on the back of his time-trial abilities.

NFTO's Bradbury claimed the second spot on the podium, with Ryan Perry (SportGrub KUOTA) pipping Matt Bottrill to third place.
Earlier in the day, Hayley Simmonds soared to an equally impressive victory in the women's race, while Scott Davies retained his U23 title.
