The Power of Membership

SORBA uses the word association in its name for a reason. We’re a formal group of like-minded people who want to ride their mountain bikes and have a great time doing it. Individuals are the heart of our organization, but one person can’t do it alone. We’ve come together, as an association, to be stronger, to have our voice heard. And we have been heard. Just look around the region at the great trails and strong chapters we have, and you know it’s working.

Your membership makes all trails possible.

Members also enjoy special deals, programs and discounts.  Find your local chapter today and learn more about becoming a member.
