Strengths: It looks fancy
Weaknesses: Pretty much the same as everyone else. When tightened as recommended, it slips about .5" every mile or so on moderate XC trails. Toaday it broke altogether see below for more details.
Bottom Line:
I've ridden this seat post and xc lite carbon handlebars for about 300 miles. The handlebars are great, no complaints. This seat post however is ridiculous. It slips when properly tightened at the clamp. Today the epoxy that adheres the carbon to the aluminum clamp failed and if I hadn't reacted so quickly would have impaled myself. I was riding on a flat section of trail, no roots or bumps and all the sudden, pop. There I stood getting eaten by mosquitoes while I picked my saddle off the ground and tried to figure out how to carry it while riding back to the parking lot 3 miles away.

Strengths: Micro adjustable clamp. Strong enough for this bike. Fifty two bucks on clearance.
Weaknesses: The cutout stess reliever allows dust and water to enter the seat tube. No good if you're gonna use this on a bike where saddle height needs to vary. Lots of negative reviews on this board.
Bottom Line:
I borrowed and tested this post a few months ago on my road bike. Easy to setup and superb ride with no slippage. At list it was overpriced. Found it on clearance for this new bike. I will post updated review if it fails during prolonged use.
The EC-70 was priced to sell and I weigh 130. . .
I ignored previous negative reviews and "rolled the dice" on this one. Its light, strong, beautiful and matches this build flawlessly. The bike is fast, comfortable and weighs under 17 lbs.
As far as using this post on my hardtail XC bike, NO WAY, the Thomson Elite stays put! Its a no brainer to anyone who inspects both posts carefully. One is a reinforced plastic tube glued into a copy of a patented Thomson clamp, the Thomson being simply the best there is. Choose your equipment accordingly.
I leave the bottom line on this to an article I found on EASTONs website concerning appropriate component selection:
"So, if you’re the adventurous sort that blazes new trails and tends to leave the bike a lot. Aluminum or thicker-walled carbon bars will work for you. If you are more the elite cross-country rider that finesses the trails you can choose a lighter bar regardless of materials. This advice applies to other components as well: seat posts, stems, forks, etc.
The bottom line is that while there are a lot of components available, it is important that you choose the right one for your intended riding style. One size does not fit all."

Strengths: light, filters small vibrations very well
Weaknesses: none
Bottom Line:
When I read all the comments here after I ordered the seat post, I was quite afraid about the quality.
But this seat post is simply great.
I fastened it by hand, and didn't touch it any more for a year.
Last week I bought a torque key and checked the torque: it was fastened way too hard all the time, but it never broke.
Now I reduced the torque and it still doesn't slip.
Great seat post

Strengths: Light
Weaknesses: -Design flaw in the clamp causes the seat bracket to slip allowing the saddle to pitch upward causing pain and potentially harm to the testicles and other organs down there (sterility/impotence anyone?).
-Non-existent product support after I made a complain to BikeSource and directly to Easton.
-After I decided that a replacement bracket may be all that's needed, I spent the bucks to order one (because Easton made me) and 1st: they make it very hard to place orders for replacement components, 2: they sent the wrong bracket the first time, 3: the replacement did exactly the same thing after a matter of ~5 hours riding time.
=====
There's no other place to mention this, so I'll do it here: I weigh ~195, which surely is part of the reason why the clamp gave out, but it fails when riding on paved streets and when the bolt is as tight as I can make it w/ automotive mechanic's tools. Surely even a light 150 LB rider will place that amount of weight on the saddle when traversing rough terrain.
Bottom Line:
Product w/ an intolerable design flaw by a company that doesn't stand behind their product and doesn't make it easy to get replacement parts.

Strengths: Looks very slick. Light weight compared to most seat-post's. I like the two bolt design which keeps it very simple.
Weaknesses: None
Bottom Line:
This seat post is a great post. I don't know about everyone else but mine had torque spec's for the aluminum fasteners and really has never slipped on me yet. A lot of people complain of it breaking which an Easton employee told me was 'from user error'. I have seen some of the testing they put these things through and I highly doubt failure was a result of poor manufacturing.
Great budget seat-post. If you every find a Thompson Masterpiece that's in your price bracket...go for that thing.

Strengths: I guess it looks cool, kinda.
Weaknesses: What a piece of crap! Constant slipping of the clap which resulted in the nose sticking up toward the sky resulting in my balls getting shoved up to navel! Clamp failed during a ride, the thread stripped and yanked the bolt right through. This seat post has given me problems from the start.
Bottom Line:
You can't argue with the majority. Read the reviews then do not buy the EC70, buy the Thomson Elite instead!

Strengths: Wieght
Weaknesses: None yet however, many people have issues with the post slipping down in the seat-tube. Easy fix...apply a small amount of valve lapping compound on the post were it will be clamped. Torque clamp properly.....no slipping!!! Regarding breakage, I suspect many are due to over tightened clamps, makes sense since they will slip if you don't use lapping compound.
Bottom Line:
Buying a CF seatpost is not for everyone! But, I've had no issues, other than figuring out how to prevent it from slipping, and have been using it for about 3 years. I weigh 170 (naked) and ride some pretty tough and technical trails. Just purchased another for my new 29er SS build!

Strengths: Looks, that's about all.
Weaknesses: Catastrophic failure for the 2007 model EC 70 seatpost!!! I have been riding this post for approximately 6 months. I live in lower Ontario, Canada, so you can imagine that there aren't very many good or hard trails in the area. Luckily I was only riding to my friends house when this happened!!! Keep in mind I ride a dual suspension bike. I rode off of a 7inch sidewalk curb, and when my back wheel hit the street, all I heard was a laud POP! I got off my bike and the EC 70 Carbon seat post had cracked right in half about an inch above the seat collar. It was not over tightened or under tightened, and I weigh 175lbs. Be very weary of this product!!! I can't imagine what might have happened to me if I were riding in the trails!!!
Bottom Line:
!!!DANGER!!!---If you value your reproducing organs, DO NOT BUY THIS PRODUCT!!! Nobody should buy this product! Stick to Thomson's :)

Weaknesses: It will look scruffy fairly soon. Then it will break. Trust me.
Bottom Line:
Don't buy this product, unless you're just going to look at it. My first one had the clamp separate from the post after approx 9 months. CRC were excellent, arranged for a new replacement. That has just failed in exactly the same way after 18 mths, riding XC summertime only (I work abroad in the winter) Fortunately both failures were at non-critical moments, but you could be in for a very nasty surprise. I am not an aggressive rider, and I weigh in at 180lb. I'm now on an aluminium Thomson Elite.
