Sonoran Desert Mountain Bicyclists is a volunteer-driven 501(c)(3) non-profit organization devoted to the promotion of the sport of mountain bicycling, and views the sport as a vehicle to promote low impact outdoor recreation, conservation, and mountain bicycling opportunities that are environmentally and socially responsible. We work to build, maintain, and protect multi-use singletrack and mountain bike trail access in the greater Tucson, AZ region. Please consider supporting us through you membership, donations, or helping with trailwork.
