Go the distance — even if it’s just a short distance. The Pioneer is the largest, toughest, rear rack Old Man Mountain has ever created.

This rack uses 6061T6 Aluminum, larger .5″ diameter tubing. An optional lower pannier mounting bar for better weight distribution options.

The new dark gray textured powdercoat finish makes this rack, we dare say, stylish. But this rack is oversized for hauling, not for fashion. But, what the hell, why not color coordinate with a matching OMM Pioneer Front Rack.
