Ever need to make a 13/16-inch seat post fit in a 7/8-inch seat tube?  Yeah, me neither. But apparently a lot of your local bike shops and manufacturers have, so they asked us to come up with an easy-to-use adapter. 

The 905 seat post bushing is so easy to use, the instructions are stamped right into the metal for quick (and permanent) reference. This versatile little tube can also be used for marrying .833-inch handlebar stems into .875-inch diameter forks.

Available in plated (905) finish only.
