The Pioneer and Sherpa mount to your brake bosses and axle. This design allows them to fit nearly any type of frame including frames: without rack eyelets, with small rear triangles, with disc-brakes, and even with rear suspension.
The White Rock mounts to lower eyelets and brake bosses and is the best choice when eyelets are available.
The Black Rock is specifically designed for Road Bikes
From the beginning Old Man Mountain has offered front racks that are perfect for both suspension and rigid forks.
If you're going off-road, check out the Pioneer or Sherpa – panniers are held higher to give better clearance over rocks and rough ground.
If you want to carry your bags lower to the ground and you don't need the convenience of a top plate, then the Ultimate LowRider is for you.
