In 1996 Old Man Mountain founder Channing Hammond developed the first bicycle cargo rack to fit on suspension bikes, using the center of the wheel as the main connection point. The company has continued to be a driving force in providing adaptable gear-carrying solutions for all bikes. In 2020, Old Man Mountain was acquired by The Robert Axle Project. The natural convergence of The Robert Axle Project and Old Man Mountain occurred as a result of the close synergy and trust of both owners, and the shared vision to provide high quality, durable components and racks to fit all bikes. In 2013, The Robert Axle Project was born from a need to attach trailers to the owners’ new thru axle equipped bikes. Within months Channing, the original owner of Old Man Mountain found the company and became their first OEM customer; using Robert Axle Project axles to continue to mount his racks at the center of the wheel.
