    • Thru Axle: 12 mm thru axle with 122 mm length and x 1.75 mm thread pitch.
    • Pair of 5" Dropouts. Attach the rack frame to thru axle to fit all fat bike tire sizes.
    • Pair of 6" extenders. Stabilize and level the rack.
    • Pair of OMM Pucks. Mount to the fork to provide an upper attachment point for the rack.
    • Stainless steel mounting hardware.
  • Our Fit Kits are tried and tested! Old Man Mountain was born in 1996 from the need to mount racks on bikes without traditional mounting points and make every bike capable of doing more. Our Fit Kits do just that while having some key benefits over eyelet mounting too.

    • Fit Kits protect your bike. Not all bike eyelets are meant for racks, most are only made for fenders or have very low weight limits. Axle mounting protects your frame by moving the load from a small bolt that's loaded in shear to a stud that extends from the axle and is captured by the rack dropouts.
    • Need to carry more gear? Axle mounting increases our Divide rack's load capacity to 70lbs/33kg.
    • Want to move your rack between multiple bikes? Fit Kits make it easy to swap between bikes or front and rear mounting with just a few bolts.
