Replacement handlebar bracket "U mounts" for the Rixen Kaul handlebar mount. 

The Rixen Kaul handlebar bracket bands are the U shaped plastic bands that wrap around your handlebars and fit into the main bracket. If your bands have broken and/or you have moved to a new/different sized set of handle bars, then these are for you.

Sold in the 26mm and the 31.8mm. 26mm is typically for retro style of handlebars that are one consistent diameter throughout the bar, and the 31.8 is for what is typical newer style bars that is thicker in the area where it meets the stem. This is for the bands only.
