"I'm very happy, top five at the world championships. I would have liked a podium but top five it is up there," said Cromwell. "I felt like maybe I had a little more, but sprinting against the best in the world I'm happy."
The Australian was ninth in 2013, in Florence, but has put focus on developing and improving her sprint, and was delighted the work has paid off.
"To get top five it shows how much my sprint has improved."
Cromwell was helped by former silver medallist Rachel Neylan, who attacked on the penultimate lap solo, allowing her team-mate to sit on.
Neylan was caught on the second climb of the day when a group of four of the race favourites surged behind; Emma Johansson (SWE), Lizzie Armitstead (GBR), Marianne Vos (NED) and Elisa Longo Borghini (ITA); who dropped Neylan and continued on together in the bid for the victory.
"It was a real team effort, thank you to all of them they really supported me," said Cromwell who was ecstatic to finish a solid 2014 campaign with the top five result.
"It is a fantastic way to finish off the year, it has been my strongest year so far. I have continued to develop and the back end of the season has been great with a lot of strong results; podiums and top fives."
Likewise Neylan was happy with her return to top level competition after two years of injuries.
"I put it all out there for Tiff (Cromwell) and it worked," Neylan said. "I couldn't be happier. To get a hug from Marv (Martin Barras) was a special thing. It meant a lot."
