So the only Poles under the age of 28 on CCC are Paluta, Malecki and Sajnok.
Paluta has no E, and you have said it isn't him.
Malecki hasn't done a *.Pro race
Sajnok is U23 and was on CCC last year.
The most likely misunderstanding (if not anglicising Paluta's forename) is probably thinking of *.Pro as meaning any professional race, rather than the new category which replaced *.HC, so Kamil Malecki?
