Seat Post Binder - Fuji CF1 - circa 2008
The Fuji Aloha is a Tri-bike with a aero shaped seat tube, therefore a generic replacement binder for a regular circular seat post will not work,

You will probably have to contact a bike store that carries Fuji products (at the time of writing that is Performance Bikes) or Fuji Bikes directly to order a replacement.



Update - because apparently neither Fuji nor Performance can help.

If a replacement really cannot be found, you could try finding a machine shop that will do custom small orders. A competent shop with a small CNC machine should be able to create a binder using the damaged one as a pattern.
