You'll have to look closely to see the differences between the Easton EC70 Zero Setback Seatpost and its fancy big brother, the EC90. It's essentially all the same with the exception of the alloy clamp hardware in place of the carbon fiber found on the EC90. With the lighter burden on your pocketbook, you'll be able to buy a substantial supply of Gu gels, one of which makes for the difference in weight between the two posts.

The EC70 uses a two bolt design for the seat rail clamp. We've found this to be generally superior to single bolt clamps in terms of minute adjustments in saddle tilt. There are no splines, teeth, or otherwise to dictate exactly where you can position your saddle. The design relies on two simple bolts to apply even torque to both ends of the clamp and each is adjusted independently of the other to secure the unit. The post shaft is made of their CNT carbon fiber and uses Easton's Taperwall and RAD (relief area design) technology to minimize the material while preserving the strength necessary for a durable post worthy of their 5 year warranty.

The Easton EC70 Zero Setback Seatpost is available with 300mm lengths in two diameters -- 27.2mm and 31.6mm. It is also available in 400mm lengths in three diameters -- 27.2mm, 30.9mm, and 31.6mm. 215 grams

Dampen your whip

Great post!

This thing really improves the ride of my full rigid rig by dampening and flexing through the chatter. Totally recommend it if you're rockin a hardtail!

EC70 Seatpost

Great Looking seat post. Actual Weight for 27.2/400mm post was 225g. Got that down to Sub 200g after fit. 2 bolt adjustment is quite the hassle, especially when making adjustments on the go but once saddle position is dialed in you quickly forget about it. One bolt design would make this a STELLAR seat post. Otherwise 4 stars!
