Sheffield, who rode for Rally Cycling until late August, has been announced as Ineos Grenadiers' third signing for the 2022 season with a three year contract.
The 19-year-old managed 10th in his U23 time trial with a solid ride that saw him finish 51 seconds down on eventual winner Johan Price-Pejtersen (Uno-X).
Sheffield spoke about his excitement of joining Ineos Grenadiers after his race: "I'm really excited to finally announce that I'll be joining in Ineos Grenadiers for the next three seasons. It's been a dream of mine, since I was really young. And to be able to join the team, this early on in my career, I think is really special. And I'm really looking forward to gaining the experience from and all the knowledge This team has. And I think it's really good fit personality wise.
"I think I'll have a pretty heavy early season, like in the spring with the one-day races. But we're just going to have the first season there's not going to be a lot of pressure. So it's just about gaining as much experience as possible, especially in these one day races where experience is so valuable.
"And actually see quite yet where I where I'll be as a racer, I think I'm an all-rounder, but I'm hoping after the first season, then I can see kind of what my specialty is and then try tune that in."
When asked as to why he chose Ineos over other options with Sheffield answering that is was all about the team being performance focussed as well as it being a young squad with second place at the U23 time trial, Lucas Plapp joining Ineos as a stagiaire at the start of August as well as Ben Tulett joining from Alpecin-Fenix.
"I think it's going to be really interesting to see because it's going to pay off the next couple of years and you'll see the team [get stronger]. The past year has been a bit difficult, but I think you'll see the team regain its strength and rise to the top again."
