IMBA Affiliated Chapters and Supporting Organizations

IMBA's hundreds of chapters and clubs form a grassroots network of riders around the world. These organizations build and maintain trails, organize social events, clinics and rides. They also work with local government representatives, land agencies and businesses to improve and protect riding areas.

A local group can affiliate with IMBA as a stand alone club or as an IMBA chapter. Chapters have taken the next step in aligning with IMBA and unifying a world wide mountain biking movement. These organziations are more closely connected to IMBA and have an increased level of support for sustaining the local group's infrastructure including joint membership, e.g., the chapter's members are also automatically members of IMBA.
