Welcome to CBMBA—the oldest mountain bike club on the PLANET! Since 1983 CBMBA has been creating, maintaining, advocating for, and putting mad love into 450+ miles of singletrack around Crested Butte.
CBMBA works to improve trails, conserve landscapes, and build community through volunteer trail work days, group rides, events, and a professional trail and stewardship crew, the Crested Butte Conservation Corps (CBCC). All trail users benefit from the work that CBMBA does. Help us build and maintain sustainable trails and conserve the landscapes around CB by making a donation, becoming a member, volunteering, or attending an event.
