In a groundbreaking effort to push trails forward in Colorado, the Colorado Mountain Bike Association and the International Mountain Bicycling Association (IMBA) have banded together. IMBA and COMBA are now working more closely than ever for the good of trails and mountain bikers in cooperation with other trail users in Colorado. When you join COMBA you are a member of IMBA and if you are a member of IMBA you are our member too!

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. Please consider supporting COMBA and local trails by making a financial contribution to our organization. We are a volunteer run, membership based 501c3 nonprofit organization. We volunteer because we love the local open space parks, trails, and rider community. All of your membership dollars go back to build and maintain trails, host events to promote the local riding scene, encourage children and youth to get outside on bikes, and represent mountain bikers at the local, state and national level.
