Now this guy!
Started as a WT pro age 25 (yea, what is a pro? - anyway, WT works for me). Now 27, silver in world TT 2017 and very good race results too. Especially seeing the growth from 2015-2107. I'll want to see what he does this summer. We may hear of him.
For a world class athlete, the switch may be easier.
