Welcome to SDMB!

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 single-track and mountain bike trail access in the greater Tucson, AZ region. Please consider supporting us through you membership, donations, or helping with trail work. For up-to-date information about trail events, social rides and other events, feel free to visit either--

We are grateful for the opportunity to live, recreate, and work on traditional Native lands, including those belonging to the O'odhamTohono O'odham, and Pascua Yaqui.


We are proud to be partners with Pima County, the Town of Marana and the Coronado National Forest to keep recreation trails open and enjoyable for all.
