• This 27.2 mm seat post mount provides a secure upper attachment point for Old Man Mountain racks for certain bikes.
  • 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 also have some key benefits over eyelet mounting.

    • 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.
    • Need to carry more gear? Axle mounting increases our 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.
