Shave weight without giving up strength.

The EC90 Seatposts are the lightest in Easton's line with a full carbon construction, including the upper and lower clamp plates. Unlike the Zero, this model features 20mm of setback.

Easton has managed to reduce weight even more thanks to TaperWall™ technology which eliminates excess material without sacrificing the structural integrity or the durability of the post. Unique Relief-Area Design™ technology is also used to prevent crimping by placing a flat section corresponding with the clamp zone.

The EC90 Seatpost is available in 27.2 or 31.6mm diameters. 350mm length. Claimed weight: 200g (31.6mm). Matte UD Carbon finish.

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

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

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