Support Mountain Biking

IMBA Local associations are member-based groups focused on trails, access, rides and social events on close-to-home trails. IMBA works with IMBA Local partners to support and enhance trail building, advocacy and organizational efforts.

IMBA’s vision is to build the quality and quantity of mountain biking communities by supporting and empowering local leadership. We want to help communities build a base of knowledgeable and capable advocates and stewards.

How can you help? Support your nearest chapter, or more than one if you like – individuals can have up to 10 chapter memberships. It's an easy and rewarding way to support the team that knows your local trails.

SORBA Tri-Cities

SORBA Tri-Cities' mission is to create, protect and enhance great mountain bike experiences in the Tri-Cities region. To fulfill this mission, SORBA Tri-Cities works towards three major goals:


Create a Community of Mountain Bikers: Part of creating sustainable trails is ensuring that there will always be a community around to care for and advocate for those trails. This isn't possible without a community of mountain bikers who understand and support our mission. We build that community around a shared love of trails, then back it up with fun social events and group rides.


Advocate for Trail Access: We have made great strides toward achieving better trails for the region and have numerous advocacy successes, but there's always more to do and we need your help to do it. 


Build and Maintain Trails: Our goal isn't to create as many trails as possible. Instead, our aim is to create quality trails that are both fun and sustainable, trails that will pass on our love of singletrack to future generations. We have developed a small army of crew leaders trained in sustainable trail building design and maintenance, and every year provide numerous opportunities for the community to give back to the trails we love to ride, donating thousands of volunteer hours to the trails in the region.
