Who Are We?

The Gravity Riders Organization of Arizona was established to promote rider education, trail advocacy, and recreational opportunities specific to the gravity community in Arizona. The gravity rider community includes downhillers, freeriders, all-mountain riders, dirt jumpers and bmx riders of all ages. The organization stands to provide a united voice for the gravity rider community to reach out, communicate, and work with city, county and state parks and land managers.

What We Do

GRO-AZ believes that rider education, etiquete and awareness are all cornerstones for building a strong, dedicated and responsible rider community as well as lasting relationships with local, county and state land managers.
Trail Work
GRO-AZ believes that good trail design and ongoing trail maintenance are the biggest factors in mitigating the environmental impact that occurs on multi-use trails and strives to build sustainable trails available for use by all user groups .

Featured in the IMBA Column, July 2012
GROAZ was featured for the Advocacy, Education and Work that we bring to the Phoenix area. We're proud of the work that we, and other gravity riding groups across the country are doing to bring the heart of the sport to all riders.


Trail Work
There are always opportunities to give back to the trails that we love so much! Learn more by coming out to our monthly meetings every 2nd Tuesday of the month, 7PM at Boulders on Broadway. For work days always remember to bring sunscreen, water, snacks and gloves. If you have specific tools you want to work with, bring those too!
