 The critical review IS correct.Feb 09, 2010
By Jeezer

I have had the EXACT same problem as the most critical reviewer noted.
The starboard & port site metric Alan-head style bolt, that holds the "arm" and allows adjustments with a 5mm metric Alan wrench, are a joke.
These are listed as #H4 EXTENSION FIXING BOLT per factory diagrams, and further (ridiculously) described with a "WARNING that the bolt has been tightened at the factory, this requires no service".
It thus FOOLISHLY does NOT allow you to adjust the angle (although the item is sold as "adjustable" in the product description).
BUT that is NOT the only problem removing it.
Bolts are heavily LOCTITE-ed into the extension arm, and heavily torqued as spec-ed at 160-170 kgf-cm, thus you are NOT going to remove them without striping/chewing the bolt recess. Wont' matter if you use Metric or SAE. They are severely locked in.
For those who criticized the OP poster for using SAE instead of metric, well children, that was NOT the problem.
The bolts need repeated hi-heat --- penetrating oil --- cool ---- and then reverse back-out drills to remove them.
In summary, a lot of trouble to go thru to adjust your "Adjustable Quill Stem"
I suspect by the yellow adhesive "info tags" on newer {2009-2010} units indicated that 'maybe' this problem has been addressed?
 first purchase from Amazon.Oct 13, 2009
By Joshua Martinez
Was exactly what I expected. I'm not really a bike person so it took me a bit to figure out how the thing worked because there were no instructions. But highly recommend this product if you want to be more comfortable by sitting upright on long bike trips.

Thats about it. Not much you can say about a piece of metal. Solid.

 Stem is decent, but BEWARE!Nov 21, 2006
By Chen Li

For the stem itself I would have given four stars. But this purchase from Performance Downhill was not a good experience. I usually only write positive reviews, but not this time.
I ordered this stem a month back for my road bike and expected to use the adjustable feature. I preferred silver finish as shown in the picture, but because I could not find other similarly priced adjustable stems, I ordered this anyway.
Shipping is fast (although the actual shipping cost is ~$5 instead of $10 charged), and the stem looked decent for the price. However, upon mounting it to my bike and starting to adjust it, the screw wore out. The problem is that it was simply too tight upon arrival. I have a set of Allen wrenches that always gets the job done with repair/adjustment of my bike, but not this time. Now I cannot even remove the screw from the stem for replacement unless I buy a screw extractor which costs as much as the stem.
I contacted Performance Downhill the next morning and was told they needed to contact to factory for solution, and no news since then. I haven't been able to use it properly. After waiting for two weeks I finally contacted the seller again yesterday asking if he could send me a replacement screw and I'll try to manage the rest of this mess, and was told that I should have used a metric allen wrench instead of an English one. This is absurd since there was NO warning on the package or whatever stating the existance of this issue. Also metric/English are only different ways of measring the size and have no difference in actual use. While I might only suspect that they did contacted the factory, I would appreciate it if they told me about it once they got this info from the factory (if at all) instead of putting me on hold for so long. What makes the experience even worse is the aggression and rudeness of the seller in communication. All this, however, is somewhat expected, given that Performance Downhill does not even have the courtsey to post a correct picture of the item it's selling, nor to charge the actual shipping cost instead of twice as much (a stem weighing five pounds!?).
The worst shopping experience and customer service I've ever had. BEWARE.
UPDATE: I just found Niagara Cycle Works also sells this same item on Amazon for $16.98+ $5.50 shipping. I'm not trying to advertise for anyone; at least they have the correct photo and reasonable shipping charge.
