Submitted by weather expert a Weekend Warrior from iowa
Date Reviewed: July 21, 2003
Duration Product Used:2 Years
Purchased At:came with FSA XL2 and xtreme
Strengths:works. can be reused. now the stem doesn't need something that is permanently fixed inside the fork.
Weaknesses:friction between top cap and stem/spacer (see below). needs 6mm hex
Similar Products Used:regular stem cap
Bike Setup:both my steel hardtails
Bottom Line:though some don't like it, the two conix i had have never failed me. they preload the headsets almost exactly like regular top caps, sans pounding a star nut into the steerer tube. maybe a bit heavier, but they make installing the fork a lot easier for me.

one downside, though, is that when you tighten the top cap, the entire top cap rotates (on regular ones only the bolt rotates) and the friction between top cap and stem/spacer adds more torque to the wrench. so at a given preload, you actually get a much higher torque on the conix top cap than on a regular top cap. just use common sense and you'll be fine.

Date Reviewed: July 21, 2003
Favorite Trail:Anything in Michaux
Duration Product Used:2 Years
Strengths:It works, can be re-used
Weaknesses:heavier than SFN. no special tools required for install.
Similar Products Used:star fangled nut
Bike Setup:K2 Zed Team, manitou, truvativ, sram, avid, mavic, blah, blah, blah.
Bottom Line:This thing works great. I have no idea what these other guys are b!tching about. I have used this on two different forks with no problems at all. You use it to get the tension and then your STEM holds the tension. NOT your top cap. I have even stripped my bike down to the frame a few times with each fork and still NO PROBLEMS. If you are looking for a re-usable alternative or something that doesn't require tools, then I highly recomend this thing. If your not mechanically inclined maybe you should stick to the nut.

Date Reviewed: July 7, 2002
Duration Product Used:Tested or demo'ed only
Price Paid: $7.00
Purchased At:Supergo
Strengths:Sounds good on paper....
Weaknesses:Piece of crap dropped it's clamping mechanism into the steerer tube....probabably my fault, but the two upper parts refuse to separate now. Don't buy this turd, stick with the fangled nut. It's simpler, cheaper and works.
Bottom Line:If zero chilis were an option, this would be it.I hope other FSA products are better than this.

Save your money for beer.

Strengths:might be good for bike that dont really go off road
Weaknesses:I had to tighten it after every ride.Now it pops out after I try to tighten the cap,no matter how hard I tighten the wedge.
It leaves deep grooves on the inside of my steerer tube

Bottom Line:waste of my money.dont buy it if you spend most of your time off road, you'll end up trying to tighten it over and over.might be good for pavement riders.I pulled mine out,Im gonna replace it with a azonic headlock.The damn thing left deep scars on my steerer tube.

Date Reviewed: February 19, 2001
Duration Product Used:Less than 1 month
Strengths:Good in theory
Weaknesses:Heavy, poor installation instructions, will not stay put
Similar Products Used:SFN
Bike Setup:VooDoo Canzo, Chris King
Bottom Line:This thing would pull out of the steerer tube when tightened. I've not had that problem with a SFN. Additionally, the added weight is not worth it. If you can't install the SFN yourself, go to your LBS and have them install it for you. You will have spent maybe the same amount of money, saved the weight and a lot of headaches

Favorite Trail:The one that doesn't kill me
Duration Product Used:6 months
Price Paid: $5.00
Strengths:Ease of installation, ease of adjustment, great colors
Weaknesses:better instructions
Bottom Line:I got this when I went from a rigid fork to my Rock Shox Jett. Put it together easily by myself, and it was my first time working on the fork/headset. No problems. Held just fine even after I hit that car door. I would recommend it to anyone.

Bottom Line:
The whole idea seemed silly. Star flanged nuts do work if you know how to install them. Don't use a screw driver!!!!!! That is only an excercise in futility. You don't need a special tool from park either. Put the cap on the bolt and screw the nut on the cap. Make sure to have the nut on so that some bolt threads are visible. Tap the bolt untill the nut grabs, place the cap on the steerer to center it and drive it home. It has ALWAYS landed dead center at the right depth with this technique. I was suprised to find out the Park actually makes a tool for this.Back to the review. A friend of mine, let's call him Fred (as in Flintstone), has all the mechanical skill of a troglodyte, decided to install his fork solo. Even with his chimpanzee skills he was able to do it no problem with a Conix. This is good because in his zeal to mount the fork by himself he forgot to put the lower race on the fork. Is that why the steering is rough?I still think it is a useless excuse for putting ano on a bike, but it does work. If he had to install a starflange I know he would have put in five or six with a screwdriver or steel punch. It does remove a possibly aggravating step from installing a fork. Its worth three chilies, it's only another bolt after all. Five chilies if you are Fred

Bottom Line:

You guys should remember that this device is for pre-load. I doesn't hold things together, the stem does. If you headset keeps getting loose, blame your stem. Anyway, other than the nut rounding, mine has been fine. I need some more words. I think the 50 word count thing is lame. So much for being concise.

Bottom Line:

What I like about this little darling is: 1)No stupid steel star fangled crap to get stuck in the steerer, and 2)No silly plastic cap that buckles when you try to tighten it. 3)No silly aluminum cap to replace the plastic one assuming that it will solve the problem. It loses 1 chili because it is a difficult fit for an aluminum steerer.

I hated the plastic that came with my original headset from day one. I went to the Club Roost from there... hated it even more. I would have to adjust (re tighten) my headset every 2 or 3 rides. Now I have a Conix. Goodbye headset looseness. This really is a great $10 part.

Bottom Line:

Great alternative to the star-fangled nut.Maybe a little heavier, but it works. Comes in several anodized colors.At first I thought it wasn't great because my headset would come loose. Turns out it was my crappy stem. Remember, folks, this Conix thing, as well as star-fangled nuts, ARE FOR PRE-LOAD. The stem is what really keeps it all in place. I think it's better than the old star-fangled nut setup because it is fully removable, and reusable should you buy a new fork (not that star-fangled nuts are that expensive, though). FSA's conix is good, as are the FSA headsets.

Bottom Line:

Got it with a new FSA headset. I went back to the shop numerous times to get the headset re-tightened. It would not stay tight. One piece was a little larger than the diameter of the head tub. The stem would clamp onto this piece and not the h-tube. I could either grind it down (not very precise) or go back to the SFN. Went back to the SFN. I also replaced the FSA head set 1 year later.

Bottom Line:

This gadget connects your steerer tube to your stem. I picked one up after getting
a new fork. The star fangled nut was stuck in the old steerer tube. The FSA Conix
works by a reusable expanding nut which is tightened inside your steerer tube. The
face plate attaches on the stem to connect the whole thing. It allows a very tight
connection between the two.

The Conix costs about 10 bucks, which I feel is a tad pricey... Otherwise an
excellent purchase if you need to replace your star fangled nut.

Submitted by Rick a weekend warrior from San Francisco, CA
Date Reviewed: June 12, 1996
Bottom Line:

Hate your SFN (star fangled nut)? I did, after installing my forks into a new
frame, I had to cut down my steerer tube to get a proper fit. Well, if you cut
down the steerer tube, you'd have to move the star fangled nut down the same
amount you cut off the steerer tube to supply enough depth for the bolt to
clamp to. I couldn't hammer the star fangled nut in evenly so that the bolt was
still inserted straight...because I pounded the !@#*% SFN nut too far down and
it was crooked! Solution? Conix Aheadset Cap to the rescue. This ultra cool
cap has an assembly that you insert into your steerer tube (a small lip helps
keep it from slipping through) and screw with a hex key to tighten. Then an
anodized cap screws into the first assembly, pulling your fork, aheadset, and
stem together. Bingo! And when you want to move it to another bike, you can!
Try that with your star fangled nut! (Comes in blk, sil, red, dark blu, lt blu
and gold for 1 or 1 1/8 steerer tubes for approximately $10.)

Bottom Line:




The Conix by FSA (Full Speed Ahead) is the best susbstitube for the SFN (star fangled nut) for the threadless headset.
The SFN scratches and mars the inside of your steerer and does more damage if you want to remove it.
The Conix is the solution. The expansion package inserts into the steerer, you tighten it with a 6mm alley wrench.
After it's secured, a top cap threads down into the expansion package, pulling the headset tight.
Unlike the Club Roost Wedgehead, this is a 2-step system. So, you make sure the expansion package is very tight first, before
you attemp to thread down the top cap. It works extremely well. Cost: $10.
Weight, about 30g more than a SFN. Plus, you get a nice alum top cap with carved in lettering.

Bottom Line:




I got the Conix with my FSA Orbit threadless headset. I wasn't supposed to have
any complaints about the 'nix, for it is a really professional replacement for the
wimpy star-flanged thingy that came with my suspension fork. Theoretically it was
supposed to be real damn easy to adjust trailside, but the glitch here was that it
WOULDN'T FIT INTO MY STEERER TUBE!! (See my review on Judy SL) After a big amount
of filing and shearing on my part, I finally gave up and used back the wimpy star
with the Conix's assembly. No doubt the Conix's design does make it easier for firm
adjustments to the headset assembly, but I keep feeling as though I've lost out on
something. Does FSA make special clamp-pieces for Judy aluminium steerers?
