Old Man Mountain Thru Axle Fit Kit

You don't strictly need it, but this kit is a superior alternative for heavy loads. By mounting the rack directly to the thru-axle, you bypass the frame's eyelets, which protects your frame from stress damage and allows you to carry up to 70lbs safely.

This kit is specifically designed for bikes with a 12mm thru-axle, a 1.5mm thread pitch, and an axle length between 223mm and 229mm. You should measure your current axle's length and check your bike manufacturer's specifications for the thread pitch before purchasing to ensure a precise fit.

No, this fit kit is engineered specifically for Old Man Mountain bike racks. The mounting pucks and hardware are designed to interface with the specific geometry of their rack systems for a secure, stable connection.

It is designed for straightforward swapping, but it depends on whether both bikes share the same axle specifications. If both bikes require the same axle length and thread pitch, you can easily move the rack and axle assembly between them.

Yes, because the rack is mounted to the axle, you will need to remove the rack hardware before you can pull the axle out to change a flat tire. It adds a step to the process, but it is a necessary trade-off for the increased stability and load capacity.
