Rollin' is the fourth mini album by Brave Girls. It was released on March 7, 2017 with "Rollin'" serving as the album's title track.
The album marks the group's first release as a five-member group, since the departure of member Yujin in early 2017, and the hiatus of member Hyeran. "Memory" and "No Rush" still feature a rap verse by Hyeran.
The group did a crowdfunding effort to subsidize their comeback on the platform Makestar, from September to December 2016, with the schedule of an album release on March 2017.
