Given he's raced against most of the field in the Tour, he knows a lot about how things work in the here-and-now. Having a recent UCI Pro Tour veteran is gold for getting the best intel. His profile pieces on things like Caleb Ewan's bike are simply awesome: informative and candid, very clear.I am finding Simon Gerrans's commentary very interesting.
This all depends on your ability to understand Flemish and/or Dutch (they're close cousins). But yes: they definitely make it exciting, and given they cut their teeth calling cyclocross races they're accustomed to a bit of... vocal hyperbole.You can’t beat the Belgian commentators (Sporza) they have such creative language, they make up the most amazing expressions on the spot.
Unfortunately most of you can’t understand them.
