Cavalier Youth was released on 27 January 2014 through major label
BMG. A mutual friend of BMG witnessed the band at
Reading Festival in 2012. Subsequently, an
A&R representative was adamant about signing the vans to the point he flew out to Los Angeles while they were recording. BMG allowed them to have the support of a major label while retaining the atmosphere of an independent label. The CD/DVD version included a making-of documentary, titled
Oceans Away, filmed during the recording process. The
iTunes Store edition included the documentary, as well as "Champagne Wishes" and the music video for "Lived a Lie". Prospect Park Records president Jeremy Summers had previously worked with BMG on releases with
Backstreet Boys and
Five Finger Death Punch; Dave Wallace from You Me at Six's management called Summers to congratulate him on the success of those two acts. Summers said the label had been aware of You Me at Six's success in the UK, with some members of staff seeing them live, being impressed by the performance. Following this, he decided to sign them. Franceschi recounted that their albums had lacklustre support in the US previously, explaining that they had never met people from
Epitaph Records, who handled
Take Off Your Colours or Virgin Records, who handled
Hold Me Down (2010) and
Sinners Never Sleep. He was adamant about the band making a push at US radio, "because it is obscene that we can have the number one selling rock single in Australia and in the UK and then not even have that song played on radio in America". To promote the release, the band did a series of in-store acoustic performances and signing events. On 17 March, a US mix of "Room to Breathe" premiered through
USA Today, before being released as a single the following day. According to Franceschi, Avron made the mix exclusively as a "unique introduction to American audiences." Summers said they picked it out of four possible choices, say it had the "makings of a great rock song - big guitars, soaring vocals and lyrics that everyone can identify with". directed by Tom Welsh. It features tour footage from their previous tours. The song was released to US
alternative radio on 8 April. "Cold Night" was released as an EP, which included live radio performances of "Lived a Lie", "Fresh Start Fever" and a cover of
the Beatles' "
Come Together" on 27 April. The following day, a music video was released for "Cold Night". "Room to Breathe" was released as a single on 28 July. The following day, another music video was released for the track. Video were released for acoustic versions "Lived a Lie" and "Room to Breathe" on 7 October and 23 October, respectively.
