Both of my main bikes have Brooks saddles and Thomson Elite seatposts. Great combo except that Thomson has absolutely no setback. And as most of you know, Brooks rails make it difficult to slide the seat back too much. Are there any other high quality AL seatposts that have more setback? One is a 27.2, should be easy to find, and the other 27.4, much smaller selection.
Plenty of seatposts that are light , adjustable , have setback and are cheap. I paid $ 15.00 for a perfectly fine seatpost in a rare size for my Fat Chance Wicked at the local LBS. It is not a complex mechanism .
