    Purchased At:nowra
    Strengths:looks nice,has markings on the back so you can see what height your at .
    Weaknesses:As you will see with the rest of the reviews .I had this seat post 3 months and snapped it jumping my single speed off a gutter(nothing out of the ordinary) . not happy jan .Admittedly I am pretty hard on the gear but not on this occasion .
    Similar Products Used:any carbon seat post .
    Bike Setup:currently minus ea70 carbon seat post .
    Bottom Line:Because the bike industry doesn t have the same quality control procedures with the manufacturing of composites that the Aircraft Industry has , It becomes a bit of a lottery as to wether a part will last and how long it will last for .The characteristics of carbon give no indication of an impending failure as alloy or steel does .I have gone back to quality alloy seat post. I tried to save the weight and paid the price . If your a weight weenie and your building a superlight race weapon this might be your thing ....but no hucking .....

    Strengths:light, takes a beating
    Weaknesses:single bolt clamp absolutely sucks
    Similar Products Used:none for mountain, only road.
    Bike Setup:xc hardtail
    Bottom Line:i've busted my collarbone riding, complete 180'd the bike and the seatpost didn't break. however, just recently ollied the bike from a 3 foot skinny and bent the seatpost. i'm 160lbs and i'm impressed that i didn't crack the seatpost and end up with it in my a**!!!! could use a dual-bolt clamp since some of my accidents have caused the clamp to strip and my seat sits on an off angle.

    Strengths:As .1 lbs heavier than its carbon twin yet a ton stronger. Clamping mechanism works well. All those people below just have to tighten it more. Never creaks (PUT SOME GREASE ON IT!)
    Weaknesses:Only that the decals wear easily but if your seat is clamped that low in your tube where it hits the decals, you probably need a smaller frame. Works Great!

    Duration Product Used:Less than 1 month

    Purchased At:REI
    Strengths:+Looked 'cool' at first...especially when you've got a full Easton cockpit (I know that sounds lame, but I'm not the only one who thought so...come on...)
    Weaknesses:-Bolt loosened on my first ride...I was riding to work!!
    -The 'graphics' are just about gone!! I've had this less than 2 weeks!!
    -Really on the heavy side (before I trimmed it)
    -Clamping it into any shop-stand (no matter how padded it is) can seem to mess with the finish
    -The setback can really mess with your riding geometry. I'm short, so I had to push the seat up super far to make it work.
    Similar Products Used:Thomson Elite, Kalloy, Ritchey Comp, Weyless, Forte Carbon, Forte Alum, Sun Ringle, and so on...
    Bike Setup:Hard-tail xc racer...use your imagination...
    Bottom Line:It's a good thing I bought this with a gift certificate to REI or else I would be really upset. I don't like to feel like I'm wasting my money so I was down that this post didn't really work out.

    Without trying to sound to superficial, I can't believe the 'graphics' rubbed off so soon! They feel like those waterslide decals you use for building models...

    Easton 'dropped the ball' here with this latest incarnation of the EA70 series. I'm sure their focus is on all the new EC stuff and CNT business.

    Buy a Thomson...you won't be sorry...

    I've got one on another bike and will either do that or buy an SDG I-Beam seatpost. You can't beat their adjustability and weight. Peace.

    Strengths:Looks nice???
    Weaknesses:Single bolt adjustment - just doesn't hold the saddle in place, had to re-adjust it every 30mins on first ride out.
    Similar Products Used:Thompson Elite
    Bike Setup:Banshee Scirorro, Moz Z1 Freeride, Hayes HFX9s, Saint crankset, Easton bars/stem, Deore/XT groupset etc etc
    Bottom Line:I sent it back within one week and exchanged for a Thompson Elite, there is no comparison between these.
    Easton make quality products but this isn't one of them.

    Weaknesses:It cracked
    Similar Products Used:Raceface XY

    Date Reviewed: June 10, 2006
    Duration Product Used:1 Year
    Strengths:Looked pretty cool for the first few months before the wear started showing.
    Weaknesses:Weak. It broke after a year of use. The adjustment mechanism is not great.
    Bike Setup:SC Heckler w/ Manitou Swinger 3way and Nixon Super +, DT Swiss EX 5.1d rims, King hub, XT crank etc...
    Bottom Line:Disappointing catastrophic failure. The seat flew off after I landed a minor jump along a XC trail. Granted, I probably hit the seat pretty hard, but there was no bend, no warning, just a snap and the silver head along with the attached seat flew right off the post. I don't think I will by an Easton seat post again. I guess it would probably do the job for careful XC use, but what fun is that?

    Now i have spent many hours on this post approx. 3,200 miles whith a few very nasty wrecks, one on pavement going 25 to 27 mph on flat ripping open seat & various body ligaments. This period of time this seat post has not moved @ all in frame or seat in cradle after reading all of these negative reports, i scribed reference markers & i kept an eye on movement to my amazement it stayed rock solid in ALL prospectives.......
    Now i weigh 175 lbs & ride fairly aggressive.
    i have found this seat post to be a VERY excellent Easton product...
    IF USED FOR PURPOSE INTENDED... :)
    Obviously by "eyeballing" it, it is not designed for the new generation of crazy kamikaze arteests.
    I would not hesitate whatsoever on purchasing one.

    I think something is going on here i gave that seatpost ( EA70) a few good thumps no creaks, movement of seat, bends or breaks no seat cradle bolt came loose either, i dunno maybe i am lucky or something.
    the seat post i would call garbage is the stock Kalloy on the 04 stumpies those are total crap.
    What does kind of look seedy on the EA70 is the radical taper at the seat cradle assembley.
    now errrr......you go from 30.9 to some small dimension (i havent measured.) now if the seat is gonna snap off & shove the rest of the mast up my a** i would say that is where it would happen.........hah!
    no probs with the mast moving in the post tube either

    Strengths:weight, ease of adjustment
    Weaknesses:durability (see bottom line)
    Bike Setup:SC Heckler- XT package, juicy brakes, Fox Vanilla fork
    Bottom Line:I would not recommend this seatpost to anyone, even a lighter weight rider like myself. The teeth on the clamp wear away over time. As a result, my seat will not stay in place. If you're going to make a single bolt design, you have to make the parts strong enough to take the extra vibration and jarring. Maybe this seatpost is not supposed to be used on Trailbikes- just xc bikes.

    Strengths:Nothing
    Weaknesses:Everything
    Similar Products Used:Thomson
    Bike Setup:Rocky ETSX-70, XT, TALAS, Thomson(Now)
    Bottom Line:Garbage. The seat rail clamp design is pure crap. Once it slides back on you (It will happen eventually if it doesn't snap first.) the clamp is stripped. No matter how much you retighten it, it will come loose again until you get so pissed off that your ride is ruined or you end up in the emergency room.

    It is ironic that the annoying creaking noise I couldn't get rid of went away after i finally got rid of my EA70, as well. Go buy a Thomson.

    I never post about a product, but someone could get hurt using this.

    Duration Product Used:3 months
    Price Paid: $70.00
    Purchased At:Local Bike Shop
    Strengths:Looks nice but that's it!
    Weaknesses:Very weak clamping action and ineffective bolt.
    Similar Products Used:Coda, Kalloy, Tahoma and other generic brands.
    Bike Setup:Cannondale F1000 Hardtail.
    Bottom Line:This seat post was an absolute waste of money. Nothing I could have done would have kept the saddle in position. The rails kept sliding back no matter how tight the clamp was. The frustration I went through was beyond belief.

    Easton may be a big company but they have failed miserably with this one. I'm even taking the new EA 70 riser bar off and replacing it with my old FSA freeride bar because it performs better.

    My suggestion is this: if you are serious about riding off road then get yourself a seat post with a dual-bolt clamp. The single bolt on this Easton simply does not make the grade. If the frustration does not kill you then shattered knees or a damaged back will.

It always creaked even though I only weigh 160lbs and to top it all, right in the middle of the derwent valley and seven miles from my car the resin inside the post snapped. My saddle flew off and the remains of the post could have caused serious damage to my arse. Do not buy this post if you have a hardtail. Your life and arsehole are more valuable.

    Similar Products Used:Various Aluminum Seat Posts

    Bottom Line:Worked fine for a year. Then it broke at the seat clamp last week. My friend had the same think happen with his. Before installation I was careful to sand down all potential sharp edges on the seat tube and did not use any grease on the post as suggested.

    I weigh 165 and ride hard but I don't usually break stuff. I am now convinced carbon fiber seatposts are a very bad idea.

    My bike was also creaking VERY badly recently. When I installed my new seatpost, no more creaking.

    Didn't have any problems with the seatpost to seat mechanism.
