Carbon Steerer Question?
Sorry I can't find this anywhere, I would like to mess around with the stem height on my Fatback carbon fork with carbon steerer. Can I put some spacers on top of the stem or does the expansion plug need to be directly behind the stem?
Needs to be under the clamping force. So yes, directly inside the stem.
If I were in your shoes, I'd get one of those $20 Kalloy adjustable stems to figure out what position you like, and then get a normal, lighter stem with the preferred angle.
Thanks Drew, I finally found it on the Niner site. After taking it apart I found that the FSA expander plug will reach down to the middle of stem with a 20mm spacer on top. Soooo by moving the spacers around and using different types of bars I found (I think) a good fit.
I do enjoy being wrong, fewer restrictions =)
Awe Drew you where spot on!! I appreciate your help above most

Thanks but it's not for a Niner fork. This is the Fat forum, sorry just like saying that.

I had to snug everything up... take the top cap off, and then tighten up the compression plug and then stem, and go back and forth a few times, till my headset stopped coming loose.
I haven't touched it in over a year now.
Was a pain in the ass at first, but, it's great now.
The Niner fork needs the stem at the top with no spacer under the cap because the expanding plug (in place of a star nut) not only provides tension for the stem, but also keeps the steerer from being crushed by the stem. I've used other carbon steerer forks on my 29er as well, but only the Niner was specific about this.
