I am replacing my Specialized Epic from a 2012 frame to a 2016 frame. The 2012 frame has a 30.9 seat-post diameter and the 2016 has 27.2. I want to transfer my Rockshox reverb from the old frame to the newer one. Is there a way of replacing only the post with a narrower one? If yes, what part do i need to order?
Unfortunately, there is no way to get that reverb down to a 27.2. You will have to buy a new dropper that fits your bike. Specialized and KS Lev are the only companies I can think of off the top of my head that make a 27.2 dropper.
