I have a 25-35mm offset 27.2 seatpost and 120mm stem. both used, both carbon. Stem is definately S-works. I don't know if seatpost is s-works or not, I don't think it says S-works on it, but it is a Specialized Carbon Seatpost. They are take-offs from a used Tarmac module I bought here on ST. Looking for Specialized or equivalent Zero offset Seatpost and 110mm stem. They are both used, but no excessive wear/tear scratches etc
