The Universal Hanger should be in everyone's saddlebags. If your existing derailer hanger busts, strips or is totally wonky, the Universal Hanger replaces the drive-side nut on your quick-release skewer so you can get the majority of your gear range back. Absolutely essential for touring and backcountry adventuring. Not compatible with thru-axle.
I purchased this hanger but it is only in my spare parts bag for an emergency. I have not had to use it in 5,000 miles but I am ready "just in case." Thank you so much!
