EC90 SL ISA SeatpostThe newly redesigned EC90 SL ISA Seatpost takes our superlight unidirectional carbon and applies our patent pending Independent 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.

Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.
