Love the Easton ISA seatpost design, but want something lighter? The new EC90 SL looks to be that post. Named for their patent pending saddle adjustment system, ISA or Independent Saddle Adjustment allows for separate seat angle and fore/aft adjustments to be made. And now it’s available in a lighter overall package.
Previously offered in the full aluminum EA90 post, ISA was also available in carbon, but it still had an aluminum head with a carbon shaft. Now, the EC90 SL steps in with a full UD carbon design to drop the weight to 195g for a 350mm long, zero offset, 27.2 post.
Already “race tested by the Easton Overland gravel team, SDG Muscle Monster, and World Cup cyclocross elite racers like Sanne Cant,” the EC90 SL post should be a good option for light gravel bike builds or road bikes still running a 27.2mm seat post.
Offered in zero set back or 20mm offset, the posts will only be available in 27.2mm diameter in a 350mm length for $199.99.
