Submitted by Russ a Cross Country Rider

Date Reviewed: June 18, 2013

Strengths:    Light.

Weaknesses:    head design. The bolt pulled through the aluminum head. Time for a new seatpost

Bottom Line:   
Got this as an upgrade after replacing the stock Specialized seatpost on an 04' Stumpjumper. The stock seatpost lasted 8 years.

The Easton Aluminum seatpost was much lighter but lasted less than a year. The bolt pulled through the aluminum. It was not dangerous as it happened over a few rides so i knew it was coming. I added a washer but eventually that pulled through too

Back to the stock seatpost for now.

Date Reviewed: January 1, 2012

Strengths:    Weight

Weaknesses:    Clamp mechanism.

Bottom Line:   
First it creaked. Cleaned the rails, paid super attention to the torque of the bolts. Then the seat shifted rearward on every ride. Loosened the bolts, retightened to torque spec again. I got the seat to stay put, but then yesterday I snapped the front bolt in the middle of a ride. I only stuck with it this long because it came stock on a new bike. Lke the rider below, I most likely will return to a Thomson.

Strengths:    Light.

Weaknesses:    Saddle slides, front micro adjust bolt difficult to get at.

Bottom Line:   
This post came as original equipment on my bike. Right from the start it didn't grip the rails firmly enough and the saddle slid backward. The micro adjust bolt at the front is difficult to get at. I've had enough and am ordering a Thomson.

Date Reviewed: April 7, 2010

Strengths:    Light, strong, stiff, 2 bolt adjustability

Weaknesses:    none

Bottom Line:   
This seat post is very light and stiff. It is noticeably more stiff than my old EA30 seat post.
Looks good and adjusts easily and precisely. "Nuff said.
And I agree, there are a lot of Easton haters here. I've always had a good experience with Easton's products.

Strengths:    Light, strong, superior to older design.

Weaknesses:    None so far

Bottom Line:   
Lots of Easton Haters in here. I purchased the 2010 version of this post. Two bolt design is improved from the old design and is much stronger and easier to adjust. Perfect fit and finish, low key artwork, adjustment lines on the tube, lightweight and a 5 yr warranty, what else do you need? I run Easton wheels and handlebars as well and am very impressed with their products, fit, finish and pricing.... well, the wheels were a little much (Havoc AM)

Bottom Line:   
I'm not pleased with the Easton EA-70 seatpost.I wanted to upgrade the seatpost that came with my mtb (GT Avalanche) with a lightweight and higher quality seatpost, so I purchased the EA-70. The pivot on the EA-70 wore out after a couple years of occasional riding, whereas the less-expensive post that came with my GT lasted 4 hard-riding college years (go Hokies!).

A poor investment ($75 wasted). Before I buy again another seatpost I will do my research.

Date Reviewed: September 22, 2007

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 .

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

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.

Submitted by Ben a Downhiller from Oakland CA

Date Reviewed: June 5, 2007

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!

Bottom Line:   
BUY. GOOD PRICE. WORTH IT!!!!

Submitted by Will a Racer from Oregon, USA

Date Reviewed: May 28, 2007

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.


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.

Date Reviewed: November 15, 2006

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.

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.

Date Reviewed: July 4, 2006

Strengths:    Relatively light and easy to adjust

Weaknesses:    It cracked

Bottom Line:   
I got the 31.6mm. Used it for 2 epic rides, 1 race and several weekends rides for 2 months. The shaft connecting the head is slightly smaller in diameter and there was the crack.

Currently, I'm with my generic seatpost.
I'm now looking for Thompson Elite or Bontrager Race Lite.

Date Reviewed: June 10, 2006

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.

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?

Strengths:    Gauges

Weaknesses:    I've ridden bike my 5 times and the post has already started to creak. OH! Crap!

Bottom Line:   
Not sure what to do about the creaking, it drives me nuts! Maybe lock tight? If this eerie sound doesn't stop, I'l have to get a new post. My frame is made of Easton Ultralite, and it rocks, so I can't get too upset.

Weird Easton EA 70 bar variance
