The possible rule violation was said to have involved Lindgren leaning forward too much and having his elbows on the handlebars.
But there was no washing up, but a second victory in Cykelvasan for the 36-year-old.
Lindgren was behind Viktor Henrysson for 12 kilometres, but managed to overtake in the race.
- You don't understand how hard it is.
Winning is one thing, but doing it this way is..., says a moved and pumped-up Lindgren at the finish line.
- I dig so deep that it is not possible to dig deeper, he says.
