Since 1988, IMBA has been bringing out the best in mountain biking by encouraging low-impact riding, volunteer trail work participation, cooperation among different trail user groups, grassroots advocacy and innovative trail management solutions. IMBA's staff, chapters, clubs and members work to benefit the entire mountain bike community.
