I recently purchased a NOS YBB 26 from a prior dealer and it has the old style Moots seat post with the two bolts in the back. I want to change the saddle, but it looks like the only way to do it is to pry open the top of the post, like a clam shell, to remove the inner barrel that the rails fit in. I'm concerned about forcing the top of the post open. I'm thinking there is a better way, or there's a trick to it. Thanks for any help.
