Hi all, I'm toying with the idea of a new seatpost for my Giant SCR2.0. The current, Giant branded post is a 27.2mm affair that uses a shim (Giant say the seat tube internal diameter is 31.7mm). The new post will have my "quick ride" saddle on it, whereas the old post would get fitted with a Brooks for commuting duties (swapping the post being easier than changing over the saddles). Has anyone used a 31.6mm post on the SCR2? Is it a good idea, or should I try & get another 27.2mm post and shim? Ta!
