Easton ISA or "Independent Saddle Adjustment" seatposts allow you to adjust the fore aft and pitch independently and securely this way affording the perfect saddle adjustment that will not move no matter how munch you do.
The newly redesigned EC70 Seatpost takes our superlight unidirectional carbon and applies our patent pending ISA technology - Independent Saddle Adjustment - which allows for completely independent fore-aft adjustment and saddle adjustment. With the 2 pitch adjustment bolts, the saddle angle gets locked into place as if you were adjusting limit screws, and unlike single bolt designs, you get adjust-ability and security.
The EC70 seatpost utilizes a forged aluminum head bonded to a carbon fiber quill. This combination delivers an impressive strength-to-weight ratio in a more affordable package.
