IMBA-SORBA's mission is to create, enhance, and preserve great mountain biking experiences in the Southeast. We have 41 chapters in seven states--Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, and Tennessee. These 41 chapters work to bring you the best that mountain biking has to offer; local trails, group rides, new trail construction, skills classes, festivals, races, and more.
