I've only started paying close attention to the sport again in the last month or so, so I'm admittedly behind on some (apparently) big stories. In the piece about a Formula 1 driver trying to get a ProTour team together for 2015 that was just posted on the main CyclingNews site, I read this line...
...Alonso's title sponsor from the United Arab Emirates may have doubts about backing the team because of the complex UCI WorldTour application process, and the radical overall of professional cycling expected for 2017...
...and scratched my head. I mean, I know they presumably mean "overhaul" instead of "overall," but what exactly are they talking about? What's the big overhaul due in 2017?
Edited to add: Ah, never mind. I did some searching of old news articles and found out about sixteen 1A teams and 1B teams and so on. All as clear as mud to me from a cursory reading, but now I know more than I did before!
