Super Light Gets Fitted

The newly designed EC90 SL ISA Seatpost takes our superlight unidirectional carbon and applies our patent pending saddle adjustment, allowing for perfect fitment with independent seat angle and fore-aft movement. ISA allows you to refine your positioning without needing to undo your rail clamps for each minute tweak. Saddle angle is then locked in place so you have the confidence your saddle will stay put after you find your fit. Available in Zero and 20mm offset, the EC90 SL Seatpost is the ultimate in finishing kit.
