This replacement seatpost is designed specifically for the 2024 Tarmac SL8, offering two different setback options to ensure the perfect fit for your bike. The post features FACT carbon construction with an aerodynamic profile. The 15mm offset version includes a 2-bolt micro-adjust clamp with a 46mm saddle rail cradle that enables an effective offset ranging from 0mm to 15mm. The 0mm offset version uses a cylindrical aluminum head assembly that adjusts fore-aft and tilt with an easy-access single bolt.
