The Cervelo single position seatpost is available by popular demand. It does not allow the adjustable geometry like the two position post, but it is lighter. It fits Cervelo road frames requiring a Cervelo Aero post like the S-series (S1, S2, S3) and Soloists (but does not fit the S5 or 2014 and newer S2 or S3). Overall length is 365mm or 14". Minimum insertion is 65mm and the length from the minimum insertion line to the saddle rails is 295mm. This post can be cut shorter if needed.
