Strengths:    Looks good, clamping area solid around
seat post rails

Weaknesses:    Post undersized having to overtighten and
possible frame damage.

Bottom Line:   
Easton's relief at the back of post combined with what seems like an undersized post for a 31.6mm. I had to really snug up post to tight up to keep from moving and my BMC Sl01 and the frame
broke at seatpost area from over tighting. Never had a problem until I tried this post and had the same problem
with post moving on other frames as well

Strengths:    Light, strong, good looking, easy to adjust tilt

Weaknesses:    Did I pay 10% of the bike's original price to replace the carbon seatpost with a carbon seatpost?

Bottom Line:   
I have experienced zero slip on my Giant. Great blend of comfortable and lightweight. I have a more comfortable carbon post, but this one is just less than 2/3 of the weight.

Strengths:    Matches my other easton bits. Light. Strong.

Weaknesses:    Have not ran into any yet other than the obvious one of price...you are definitely paying a premium here for relatively little impact on your ride.

Bottom Line:   
I have nothing but good to say about this seatpost. Was going to buy the ec90 but kept reading about the carbon clamp breaking down under heavier riders...Decided to go with this as I weigh 185. Could not be happier. The clamping mechanism works very well and allows any angle of adjustment I need. The seatpost does not slip for me at all as a previous reviewer complained of. Works perfect. Very light after I chopped it down :)

Strengths:    weight

Weaknesses:    cost

Bottom Line:   
Never had the problem of falling into the tube. It seems like easton overbuilt the aluminum top cap to bump the weight to discriminate from the ec90, which irritates me a little. But, I guess that is how we get the opportunity to buy this caliber of post for considerably less than the ec90. Overall this thing is strong and light. Absorbs shock. Finish sucks but can't take off points for cosmetics. Expensive, but thats the price a weight weenie must pay.

Strengths:    Weight

Weaknesses:    Can't get it to stay put. Slips very easily.

Bottom Line:   
I bought this post and used it on 4 rides of about 25 miles each. The first ride, I installed it and tightened it by hand (no torque wrench). By 8 miles into the ride the post had slipped all the way down into the seat tube. The next day, I had a bike fitting and the fitter tightened the seat post - went for a ride and 10 miles in, the post slipped all the way down again. Bought a torque wrench, tightened to specified torque. This time it didn't slip as fast - only slipped 2 cm after 25 miles. Same thing on fourth ride. No grease in my seat tube (as recommended) and the bike shop even tried once. I'm now using a FSA seat tube that works perfect.
