I wanted to reduce the vibration from the front end and switched from my aluminum stem to the EC70. It accomplishes this goal. The top lock instructions could have been better displayed in the included materials.
Easton's EC70 stem ticks all the boxes.
Light, nice finish, durable.
The stem seems to dampen road vibrations well, and is also nice and stiff where needed for quick handling.
It pairs well with the EC90 carbon bars.
