Description The EC90 Seatpost provides aggressive weight savings and excellent durability with a comfortable 20mm of setback.
This post is entirely constructed from Easton's top EC90 carbon fiber, including the upper and lower clamping plates. Taperwall™ technology lowers weight without giving up strength, and the Relief-Area Design™ places a flat section corresponding with the clamp zone to prevent crimping.
The EC90 Seatpost is available in 27.2 or 31.6mm diameters. 350mm length. 20mm setback. Claimed weight: 200g (31.6mm). Matte UD Carbon finish.

Snapped after going off a curb.
Tonight I rode off a curb while seated and the post literally snapped (two days before my next race).

Poor hardware, poor EASTON customer support.
Purchased this seat post less than 1 year ago on May 13, 2017. Torqued seat to below spec (50in-lbs) using a CDI torque wrench (made by Snap-on) and the cap of the hardware which holds my seat on has developed a crack with use. Called EASTON to activate warranty OR purchase new hardware. They informed me that they do not deal directly to the consumer in the case of getting replacement hardware even if I was to buy it and that I need to go to a EASTON certified dealer (2hrs away) to get warranty assistance. I did not purchase this item through bike tires direct, although I did contact them. It seemed that they were sincere in helping me but I found the hardware I needed online and would rather just buy and have the new hardware and fix my seatpost sooner than later as I continue to bike on the trainer during the winter. About me I am 5'7 and 170lbs with FTP of 250, I do sprint tri's and local duathlon's and banked about 1,000 miles this year on the bike. This failure should not have happened. I do not recommend this product, I recommend purchasing another brand.

Absorbs vibration well.
Adjusts front to back nicely. Real PITA to get the seat rails into the grooves when first installing.

I love this seatpost!
Beautiful design, looks awesome! Dampens vibration great with a stiff aluminum frame set, best seat post I've owned!

Beautiful Seatpost!
This seatpost is absolutely beautiful... light and strong (so far!). The available sizes were limited, but the 31.6 fit my frame perfectly. The 20mm set back is the correct offset for me. No slippage in the frame or seat, with carbon lube, the clamp holds the seat firmly. Highly recommended.... Jeff
