I'm looking for a replacement seat binder for a 2008 Fuji Aloha CF1 - The one I had cracked and will no longer work.

I have contacted Fuji but they politely laughed at us!

Most shops looked through their "junk" cabinets with no luck.

What can I do to replace the seat clamp?

Here is the photo of the seat clamp.

  • Hi Mark - I'm going to combine your answer into your question, and add some more info. If I error or loose your meaning then please use revert or edit again. The one thing that would make this better is a clear photo of your existing seat clamp showing how it broke. – Criggie Jan 31 '18 at 0:16
  • Go to a hardware store and get a spiral hose clamp. – Daniel R Hicks Jan 31 '18 at 1:42

    Looking at pictures on the web I see several different setups for the seatpost. With some the clamp appears to be an entirely separate piece, with some it appears to be a clamp around the top of the seat tube, and with some it appears to be integrated into the seat tube. A close-up picture of your clamp would be most helpful. – Daniel R Hicks Jan 31 '18 at 1:44
  • I think this question is totally on-topic. albeit lacking a photo of the damaged clamp. – Criggie Feb 1 '18 at 9:57
  • It's not clear where the clamp broke. – Daniel R Hicks Feb 2 '18 at 0:28

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.

  • You really don’t need a CNC mill for a one off. – Eric S Jan 30 '18 at 23:10

    Yes, but it will make machining the aero shape of the seatpost and seat tube a lot easier! – Argenti Apparatus Jan 30 '18 at 23:15

    It is service like this that puts people off a brand for life. – Criggie Jan 31 '18 at 0:17

    @Carel Does "The wheel was put on backwards" count as a technical reason? :-) But, regardless of which side it's on, having it face forwards is a bad idea in case it catches on something (whether or not that results in the QR being opened). – David Richerby Jan 31 '18 at 17:58

    @DavidRicherby: didn't even want to mention that, but of course, yes! :-D – Carel Feb 1 '18 at 18:16

Through face book found a contact at a distributor....came up with a part # - SP8035

Using that part number we found out they had it in stock....ordered 2!


  • Its not a great answer but it is an answer and what worked for OP. Plus it shows the exact part number for this bike so that is useful information. – Criggie Feb 3 '18 at 4:55
