Support RFMBA!

As a 501c3 non-profit, we rely on Annual Memberships, Business Sponsorships, Direct Donations and Grants to fund the work that we do on behalf of the mountain bike community in the Roaring Fork Valley.

Your support allows us to continue expanding our efforts to create and sustain the best possible mountain bike trails system and experiences in the Roaring Fork Valley and beyond.

Significant support for programs that increase volunteer stewardship, like our Trail Agent and Bike Giveaway Programs, or generous support for specific trail construction projects (through direct donations to the RFMBA Trail Fund) will also directly impact our effect on our local communities.
