Lanterne Rouge. Dunno who this Aussie kid is but he knows his stuff. Best analyses I've seen of pro racing. He breaks down the subtleties of road racing really well. He's like The Wolf from Pulp Fiction -- thinks fast, talks fast, probably takes his coffee with lotsa cream, lotsa sugar.

Juliet Elliot. Very relatable stuff for the Everyperson who struggles to seriously enjoy competition. That voice, tho'... I think she might be Julia Child and Graham Chapman reincarnated as a cyclist.

And most of the above listed by other folks.
