Easton Cycling’s EC70 and EC90 ISA Posts Won’t Slip on Remount

A common issue plaguing seatposts on ‘cross bikes is the inevitable slipping at the saddle rail clamp. The ISA system, or Independent Saddle Adjustment, allows you to lock in the saddle’s position with two bolts, ensuring your saddle won’t slip on remount. See the new EC70 and EC90 posts at Easton.
