    Strengths:    Light weight, bling factor for anodized blue color..

    Weaknesses:    clever design? hard to adjust seat angle, not so durable clamping design seat post, price if purchased brand new..

    Bottom Line:   
    U.S.E. Alien aluminum 350 seat post is one of lightweight post out there, however the clamping design is weird and hard to adjust seat angle, once adjust forget it.. mine the one peice bolt screw was worn out and my saddle creeks, so i reolace it with long philips screw type bolt and clamping it with nut in both ends till tight and bingo! i amazed for the design of seat post is truly strong and stiff and no problem at all.. i recomend this seat post for light weight xc rider only.. 4 chilis for value rating cause for complicated clamping design..

    Strengths:    light weight, bling, titanium

    Weaknesses:    clamp design, customer service

    Bottom Line:   
    review is for the titanium version.

    the standard clamp wouldnt fit my selle italia carbon rails.
    looked up from their website and found it requires a special clamp which will costs extra money. i reckon i paid well enough already.

    then, they failed to provide detailed info and product code on their website for me to order from my supplier.
    plus received zero email response after requesting support.

    It finally took me sometime to modify the clamp myself to make it works.

    my another Thomson seatpost can be installed in 5 minutes - no brainer.

    Strengths:    Very light, Perfect for taking the edge off.

    Weaknesses:    Seat clamp is a pain in the ass to adjust. Durability.

    Bottom Line:   
    NOTE: This review is for the U.S.E. Alien Ti seatpost.

    The bottom line - it broke at the seat post after 3 months. I'm 5' 8" 157lbs. That's it.

    U.S.E web sight says post has been in Tour De France and World Cup Mountian bike chanpionships. Also says warranty void if post snaps at theframe like mine did. Would give a better rating if I got one year out of it.

    Strengths:    Very, very light for it's price

    Weaknesses:    clamp, maybe.... It's light and tight, but a pain (impossible?) to adjust on the fly.

    Bottom Line:   
    Don't think you'll every be able to adjust this post on the trail, it just won't happen. The clamp is wierd, but workable - if you're fussy then it's not right for you, as the setback and angle will change slightly as you tighten it down. Trying to adjust it on the trail is definately a bad idea - the 2.5mm allen bolts need a good bit of torque to get them in place and are easily rounded out if things are anything less than ideal. Could easily be improved if the bolt heads were larger. Of course you could be like me and use a small pair of vicegrips to turn the bolts if you round them out a bit - I'm saving what bolt head I've got left for a trailside repair when I don't have any vicegrips with me. Sure is light though...

    Strengths:    Lightweight, looks trick.

    Weaknesses:    Adjusting the saddle in a hurry is not possible. Fortunately i've never had any need to do this.

    Bottom Line:   
    Has been in use for over a year now and has completed more than 4000kms, at least half of that in proper offroad riding and racing. Not a single problem at all, nada, zip. Can't fault this post.

    Date Reviewed: March 8, 2005

    Strengths:    The strength of the clamping mechanism is unbeatable. Once you do get the saddle positioned correctly and tightened down, it will never move. If for some reason you need to remove or reposition the saddle later, simply make some reference marks on the saddle rails and the clamp and putting it back together is a breeze.

    Weaknesses:    I had trouble with the anodized finish being so slick that the post would constantly twist in the clamp. After months of slapping the saddle's nose in one direction or the other to straighten it out, the clamp broke loose from the post. I wrote customer service at U.S.E. twice but recieved no response. I ended up drilling a 1/8" hole through the clamp and the post and installing a stainless steel pop rivet that was coated with metal epoxy (J B Weld). I figured the SS rivet would be more durable than an aluminum one. It worked perfectly. I also ended up buffing the anodizing off of the post and now it doesn't spin in the clamp.

    Bottom Line:   
    This seatpost is not for someone who doesn't want to spend a lot of time setting it up. For those who don't mind a little extra time on the rack, it is a very light post that will grip a saddle like no other. But don't expect any customer service if you have any problems.

    Bottom Line:   
    ... 2 years since giving last review for this product (check out below)...
    Its reliability is truly fit and forget.
    Absolutely no creaks coming from the seat clamp to seat post joint. And the saddle (Selle Flite TT 155gms) has not slipped in the slightest.
    Clamp bolts have slightly rusted but no seizing of components in the clamp mechanism.
    Finally, the blue anodised finish has been very durable.

    How many products on your bike have performed so well that you'd give them another review 2 years later?
    Great product.

    Strengths:    Light, Great product support, light, knowledgable product support, light, durable, and did I mention light?

    Weaknesses:    Proprietary seat clamp takes some getting used to, but how often do you replace a saddle?

    Bottom Line:   
    AS you can see from my previous post, I have used this for over two years and over 3000 miles with no problems until recently. Came down hard in the saddle, and it slipped to a steep nose up. Upon inspection, I noticed center block had cracked. Called up the tech support for U.S.E her in the USA and he is sending a replacement at no charge. After he took my info, he asked which saddle I was using. I mentioned I was using the Terry fly. HE responded that with some Terry model saddles it is necessary to tighten the bolts beyond the reccomended setting which will crack the center block. He sadi they are aware of this and they are working on a fix. He suggested I use a Selle saddle, which is just as light and works fine. Since I am in the market for a new seat, it was a great piece of advice. Two thumbs up to the customer support. A free replacement part always beats shelling out the dough for a new part.

    Strengths:    Very light weight, good looks

    Weaknesses:    Difficult to adjust, fragile

    Bottom Line:   
    Difficult to install seat and adjust position. No way you can quickly adjust seat angle or layback out on a ride--it is a several-minute operation. Personally I'd rather put up with a few more grams for easier adjustability.

    After a hard crash (that broke my collarbone and put a dent in the top tube of my Ti frame) the bond between the metal head and the CF shaft failed. It was extremely difficult to remove the post from my frame after that.

    Weaknesses:    slips after 3-4 hr ride...adjust..tighten...adjust..tighten....snap o rama of the inner bolt. Should have bought a thompson.

    Bottom Line:   
    I'm quite angry I couldn't find a Thompson seatpost at the bike show. The alien looks cool but just.....SLIPS....I wrote the company on their webpage and have yet to hear a response. It's just easier to carry this post around in my tool box and pop it out at the trail parking lot to promote bad press for the product and company.

    Strengths:    lightweight, nice look

    Weaknesses:    innerblock cracked

    Bottom Line:   
    set-up is not especially difficult just need to pay attention. adjustment is fairly easy..seat clamp is (was) very secure. i liked this post right off, design is clever and it has that set it and forget touch which i appreciate in bike components. rode it about 7 to 10 hours a week right through winter when i noticed a little give after about 3 months. thought it just needed to be tightened but the seat flipped up a bit and on inspection i found the inner block to have cracked and spread. u.s.e. is replacing the part for free. the inner block clearly suffered metal fatigue. this failure had nothing to do with faulty installation, mounting insrtuctions were followed explicitly. the clamp is of a design that doesn't seem likely to fail catastrophically so i'll give it another try.i would not recommend this for a heavier rider.

    Strengths:    Crazy Lite! Ultra Stiff! Super Strong! What else do you need?

    Weaknesses:    Reveiws stating that the set up of the seat clamp is a pain, need to be ignored! It is surprisingly simple if you have the mental capasity to figure it out, something other reviewers seem to be lacking.

    Bottom Line:   
    This post is a must have for any serious XC racer. Why you ask? It is drop dead sexy, what else matters? Instalation Instructions: Take out bolts w/ washers-Slide out back and center pieces-Place center piece on top of rails-Slide center piece onto post-Place back piece under rails-Instal bolts-Tighten 2-4 turns per bolt-Repeat until bolts are close or flush with front piece.

    Strengths:    Looks, the red anodizing looks sharp. Weight one of the lightest aluminum post out there. Holds seat secure.

    Weaknesses:    The USE lettering is wearing off. It's difficult to adjust the seat to different angles.

    Bottom Line:   
    It's a great seat post if you want light and strong. Once you get your favorite saddle on and adjusted..leave it alone. The top mounting device is more difficult to work with compared to other brands.

    Weaknesses:    None!

    Bottom Line:   
    Best seatpost I have ever use. Better feel then carbon post. Not only assorb shock, it's clamps allow the saddle rails to flex for more confort. Clamps are simple to use and so far after 200+km no slip. Was at 1st afraid of breaking the skinny hex screws but just do not over tighten and follower the instructions and it smooth sailing all the way.
