What is the relationship between PMBA and IMBA?

PMBA is a local chapter of the International Mountain Bicycling Association (IMBA). This relationship grants PMBA its non-profit status among other benefits including handling PMBA’s membership registration and database. Only $15 per year of your membership fee goes to IMBA for trail advocacy at the national level; the rest remains with PMBA to be invested locally.
