who we are

Mountain bikers are passionate about creating and sharing trail experiences. A completely volunteer-led movement has independently founded 16 mountain bike organizations throughout Oregon.

The OMBC is made up solely of representatives from these organizations. These representatives work together, at the direction of their members, to democratically develop stances, policy, strategy, and improve mountain biking in Oregon.

Northwest Trail Alliance

Northwest Trail Alliance is an all-volunteer, non-profit organization based in Portland, Oregon. We are one of the Northwest’s leading mountain bike advocacy and trail stewardship groups. Created in 1988 as a grassroots club of local riders, focused on maintaining bike access to Forest Park – Portland’s renown urban park -, we have grown into a regional advocacy group, stewarding trails and advocating for trail access across a wide radius around Portland; from Forest Park and Powell Butte within the city limits of Portland, to the southern foothills of Mount St Helens, to the western slopes of Mount Hood, to Tillamook State Forest and Scappoose.


Oregon Timber Trail Alliance

The Oregon Timber Trail is an iconic 670-mile backcountry mountain bike route spanning Oregon’s diverse landscapes from California to the Columbia River Gorge. It is a world-class bikepacking destination and North America’s premiere long-distance mountain bike route. It runs south to north and travels through a variety of landscapes, communities, ecosystems, terrain, and, most importantly—mountain bike trails. The Oregon Timber Trail Alliance is dedicated to stewardship, education, community, and quality trail experiences throughout the Oregon Timber Trail corridor.


Salem Area Trail Alliance

We connect the community to trails by:

  • Building, sustaining, and advocating for recreational trails used by bikers, hikers, and runners.

  • Providing a variety of trail experiences.

  • Creating opportunities to connect with others on and off trails.

  • Assuring financial sustainability by partnering with businesses, organizations, and individuals.

  • Collaborating with other trail related organizations.

  • Recruiting, training, educating, and retaining volunteers.



 Trans-Cascadia Inc was founded by a group of long-time, bike-industry professionals that hosted the first race in 2015. The event is part of the non-profit’s larger mission to promote and build sustainable trails in the Pacific Northwest.  Their work is made possible by the community of racers, volunteers and sponsors that help put on the event and participate in trail-building days.


Team Dirt

Team Dirt is a mountain bike club and chapter of the IMBA. It was originally founded as a bike racing team in the Corvallis Oregon area. Since that time, it has grown into an organization advocating for all biking activity in the Benton County area. Team Dirt supports urban (Pump Track, BMX bike park, bike paths, and community events), as well as, traditional off road riding (XC, All Mountain, and DH/Gravity).

Cycling is an activity that brings people together, rather than dividing them.
