Membership & Fundraising

This Program does not have a location set.

Support COMBA, a chapter of IMBA, through your tax deductible membership or donation. COMBA is a membership funded 501(c)(3) non-profit organization. Your membership dollars go back to build and maintain trails, host events and rides, encourage youth to get outside on bikes, and represent mountain bikers at the local, state and federal level. For one membership contribution you get both a COMBA and IMBA individual, family or retailer membership.

You can support COMBA in many ways. Consider volunteering and helping with one of our trail building, political advocacy, or social events and be sure to spread the word to fellow riders about the importance of giving back to the local community and local trails, but in the end, building trails, being active legally and politically, and hosting rides and events takes financial resources.

Or help support us by making a tax-deductible donation

Transactions are secure via PayPal and are tax-deductible. Your personal information is not shared nor sold to anyone. Or you may donate by writing a check and mailing it to: COMBA, P.O. Box 280415, Lakewood, CO 80228-0415
