Although several elite gymnasts were turned away, the final rosters are loaded with talent. Here's everything you need to know about the 10 Americans who will look to take home the gold in London.

Men's Team

The men's team is a young and promising group, and they will be considered among the favorites when the games begin. 

Sam Mikulak and John Orozco are both 19 years old, while Jake Dalton and Danell Leyva are 20. Jonathan Horton, 26, is the only veteran of the group. In the 2008 Beijing Olympics, Horton took home the silver medal in the high bar and earned a bronze in the team event.

Dalton and Mikulak are still competing in college, where they've both won an NCAA all-around championship. Dalton, a junior at Oklahoma, is the reigning champion, while Mikulak, a sophomore at Michigan, won the title in 2011.

Dalton excels in the vault and floor exercise events, while Mikulak is a great all-arounder. Joining them in the quest for all-around gold will be Leyva and Orozco, who earned the top combined scores at nationals and last weekend's trials.

The United States men's team last won gold in 1984. With possibly the most talented team in U.S. history, this year's squad has a great chance at ending America's gold-medal drought.

Women's Team

2008 Olympic champion Nastia Liukin was left off the roster, but the U.S. women's team is still very strong.

Jordyn Wieber, a DeWitt, Michigan native, is perhaps the favorite to win the gold after claiming the title at the World Championships last fall. However, as good as she is, she was bested by compatriot Gabby Douglas in Sunday's trials.

The 16-year-old Douglas won the individual all-around title, beating Wieber by 0.100 points. She struggled on the beam, but she was unbelievably good on the uneven bars and the vault. She will be a top contender for the all-around title in London.

Aly Raisman, who finished third at the trials, will also be a major threat in London. The last two finalists, McKayla Maroney of Long Beach, California and Kyla Ross of Aliso Viejo, California, will also look to contribute to the women's team, which should be among the best in London.
