• This thru axle is for attaching an Old Man Mountain rack to the rear of a bike that has a 12 mm thru axle with 1.75 mm thread pitch and 174 or 167 mm length with included spacers. We partner with The Robert Axle Project to supply our thru axles.
    • Diameter of thru axle is 12 mm.
    • Thread pitch is 1.75 mm.
    • True length of axle is 174 mm, but can be shortened to 167 mm with the included spacers.
  • If your bike has eyelet mounts on the front or rear dropouts, this kit will fit your bike. Keep in mind our racks are rated to 70 lbs only when mounted to the thru axle. Eyelet kits are rated to 45 lbs, which should be more than enough for most adventures, but does not take full advantage of the carry capacity of our racks when mounted to our thru axles.
  • This Fit Kit contains all the parts to mount an Old Man Mountain rack to the front of a fat bike with a 9 x 135 Quick Release Skewer: 9 x 100 QR Skewer, pair of 5" dropouts, pair of 6" extenders, pair of pucks, clear protective tape, and all mounting hardware
  • When you need the extra space that rack bags provide, but need something that will not get in your way when the going gets strange, Nano Panniers are the ticket! These bags were designed around Old Man Mountain racks, making them a perfect fit. Designed to carry dense and heavy stuff like food, water and fuel in a low profile form. For shorter riders who need to run a rack due to limited carrying space elsewhere, these bags are your new best friend.

    At only 4" wide the load stays tight to the bike on singletrack and will not get in your way on those nasty hike-a-bikes. An external compression system keeps the bag snug at various load levels.

    The devil is in the details on our rack attachment system. Although simple in concept, the tight spacing between the aluminum loop and strap prevents slop at the pannier rails. A bomber Voile nano strap with metal hardware provides tension at the bottom and gives versatility in mounting.

    Fiberglass stiffened high density foam frame sheet gives the bag internal structure and works with the external compression system to transfer load to the rack.

    Made with 200 denier UHMWPE / Polyester woven laminated fabric, the Nanos have a minimum of seams for durability and water resistance, plus double taped lower seams.

    Old Man Mountain racks are the most versatile racks available. Capable of mounting to full-suspension mountain bikes, gravel bikes, road bikes, fat bikes, even tri-bikes if that's what you're in to. Tested and trusted in the most extreme environments on earth (we're still trying to get NASA to take them to the moon). Our racks have helped riders traverse Iceland in bitter cold winters, carried the gear of countless GDMBR riders, and circumnavigated the globe. The only remaining question is where will it go with you? Want to use our rack on a bike that isn't made for racks? Want to swap your rack between multiple bikes? A Fit Kit is all you need.
  • This Fit Kit contains all the parts to mount an Old Man Mountain rack to the rear of a bike with a 10 x 190 mm hub skewer: A QR Skewer, a pair of pucks, and clear protective tape.
