The move continues the rapid rise of the 23-year-old who only began her cycling career in 2018 at the World Cycling Centre in Switzerland.
Currently riding for Valcar - Travel & Service, The Trinidad and Tobago native claimed third at the Vuelta CV Feminas as well as a fifth-place finish at Omloop van het Hageland this year before the coronavirus pandemic forced a premature end to the season.
Campbell said her move to the top tier of Women's Cycling next season has come far quicker than she had ever expected
“Mitchelton-Scott has been my dream team ever since I was in the World Cycling Centre, some days I have to pinch myself to believe it’s actually happening," she said.
“I never thought I would get to this point so quickly… to be performing so well amongst the best in Europe was really a shock to everyone because they wouldn’t expect me to fit in so quickly and already be a force to reckon with on the circuit.
“To be given this opportunity here to continue growing and to give them the chance to help me grow and develop is really exciting because they have a lot of top-end riders, they have been here for some time now and you can progressively see how strong they are, how they develop a lot and how well they work together as a unit."
A time trial specialist and a powerful sprinter, Campbell has revealed she hopes to become a contender in Classics races and even at stage races.
"There’s still so much to discover about myself because I am so young and there’s so much to learn and improve on so you never really know (what type of rider I am)," she said.
"In the first year in the WCC, Alejandro (Gonzales-Tablas, Mitchelton-Scott director) told me that he believed my characteristics were for the Classics, I also believe I am a Classics rider, but you never know, maybe I can be a general classification contender.
“I just want to gain so much experience and knowledge because you can have all of the power in the world but if you don’t have the experience, that team around you to really push you and help you grow, I don’t think the results will come.”
