Specialized S-Works Tarmac SL7 carbon post with a 20mm offset with a length of 380mm. This came off my Tarmac SL7 and selling this as I have gone to a zero offset seatpost hence it's not been used. This is also compatible with the 2021+ allez sprint. This won't have a port for a 11 speed di2 junction box. So if planning to use it on a 11 speed di2 bike you will need to have the junction box on the stem or in the handlebars. UK delivery or London collection.
