The Easton EA90 Seatpost is designed for performance-minded cyclists and gravel riders who demand precise bike fit adjustments. Its standout feature is the Independent Saddle Adjustment (ISA) system, which allows you to dial in your saddle angle and fore-aft position separately. While it offers superior adjustability and security, users should note that the 20mm setback and 350mm fixed length may not suit every frame geometry or rider preference, requiring careful measurement before purchase.

Yes, the post is compatible with standard 7mm round rails and 7x9mm oval carbon rails.
The post weighs approximately 265g.
This specific model comes in a fixed 350mm length.
The 20mm setback moves the saddle further behind the centerline of the seat tube, which can help increase cockpit reach and ride compliance.
The ISA system allows you to adjust the fore-aft position of the saddle rails without unlocking the separate pitch adjustment bolts.
Verify that the ISA locking bolts are tightened to the recommended torque specifications.
Ensure the saddle tilt clamp is fully loosened before attempting to slide the rails.
Clean the seat tube and the post, then apply fresh carbon assembly paste.
Installation should be performed using a calibrated torque wrench to ensure safety and prevent structural damage to the post. When mounting your saddle, ensure the clamp is configured for the correct rail diameter (7mm vs 7x9mm). Regularly check the ISA bolts to confirm they are tightened to the manufacturer's specified torque. If riding in wet or gritty conditions, it is recommended to periodically clean the clamp assembly and apply a thin layer of carbon-safe assembly paste to the seat tube to prevent slipping and galvanic corrosion.
