Easton EC90 SPThe Easton EC90 SP seat post combines tough, lightweight materials and clever design to create a durable, functional and stylish seatpost. This post is similar to Easton’s classic EC90 Zero in terms of its minimal weight and durable materials, but incorporates a 0.8” setback to let riders customize their bike fit.
Everything in the EC90 SP is made from harder-than-steel carbon fiber, even the clamping plates to reduce damages during maintenance and repairs. For added strength, Easton’s Relief-Area Design (RAD) and TaperWall technology serve to distribute stress along the entire surface of the post and prevent surface fractures. Reduced volume in clamp zones also reduces the possibility of cracks along critical stress points. This seat post weighs just over 7 oz. and can add plenty of strength and durability to your bike without adding much weight. Combining strength and beauty, the Easton EC90 SP seat post even comes with an attractive matte carbon finish.
