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.

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

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

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