Old Man Mountain Axle Pack is unlike any fork mount adapter you've seen. Rather than trying to clamp to round or tapered surfaces and just hope it doesn't slip or spin, Axle Pack is, you guessed it: Thru Axle mounted! Attaching to the axle makes it impossible to slip or spin. Axle Pack is lightweight, reliable, robust, and rigid. With four mounting points you can also choose to run your gear higher or lower depending on your needs. Mounted to one of our Fit Kits, Axle pack is also easily swappable with any of our racks so you can pack the right gear for the ride. Have a carbon road bike? Perfect! Suspension fork? Perfect! Aluminum bike but you don't trust the rivnuts? We've got it! Long story short, if you have a thru axle fork, we have an Axle Pack ready for you. Axle Pack mounts to our Thru Axle Fit Kits. After you add the Axle Pack to your cart you can use this Fit Finder to get the correct Fit Kit.
