Can't think of any other sport where they feel the need to do this.....They don't think any new viewers have the nous to just Google it!!??I think good commentary needs to assume a portion of the audience is new to the sport and welcome them with periodic explanations. The show broadcast time is long and viewers, new to the sport and the experienced, pop in and out so you can't limit the cycling lessons to just one segment.. I'm always surprised in these threads when a know it all fan gripes about it.
