FAQs
What is the primary material of the EA70 seatpost?
The EA70 is constructed from Easton's high-grade TaperWall aluminum tubing.
Does this seatpost include a setback?
Yes, this model features a 20mm setback to assist with bike fitting adjustments.
Can this seatpost be used for mountain biking?
While it is durable enough for many terrains, it is optimized for road and gravel. Ensure your frame diameter matches the post before use.
How do I adjust the saddle tilt?
Use the two-bolt head system: tighten the front bolt to tilt the nose down and the rear bolt to tilt the nose up.
Is this post compatible with carbon fiber frames?
Yes, but ensure you use proper carbon assembly paste instead of standard grease if required by your frame manufacturer.
How often should I clean the seatpost?
It is recommended to clean the post and re-grease it whenever you perform routine bike maintenance, or after riding in extremely muddy conditions.
Troubleshooting
Saddle tilting during rides
Ensure both bolts are torqued to the manufacturer's recommended specifications and use a small amount of thread-locking compound on the bolt threads.
Creaking sounds coming from the seatpost
Remove the seatpost, clean the frame seat tube and the post thoroughly, re-apply fresh grease, and re-install at the correct torque.
Difficulty adjusting saddle angle
Loosen one bolt slightly while tightening the other in small increments to gradually shift the tilt of the saddle platform.
Pros and Cons
Pros
- High-strength TaperWall aluminum alloy construction
- Precise two-bolt micro-adjust mechanism
- Reliable and durable black anodized finish
- Effective 20mm setback for refined bike fitting
Cons
- Heavier than carbon fiber seatpost models
- Limited to one setback option (20mm)
- Aluminum lacks the vibration damping characteristics of carbon
Setup, Compatibility & Care
To install, first apply a light layer of high-quality bike grease to the post before insertion to prevent seizing, especially in carbon frames where friction paste may be required instead. Use a torque wrench to tighten the two bolts on the saddle head; ensure both are tightened evenly to avoid uneven pressure on the saddle rails.
Check the seatpost diameter of your specific frame before purchase to ensure compatibility. For care, wipe the post clean after every wet or muddy ride to prevent grit from scouring the finish. Periodically check the bolt heads for any signs of oxidation or wear, and re-torque the hardware every few hundred miles to ensure security.
