Model Summary
Nothing is faster than the Tarmac SL8 — after eight generations of development it's not just the fastest Tarmac ever, it's Specialized's fastest race bike, full stop. The Tarmac SL8 Frameset – FACT 10r Carbon gives you the full aero and ride-quality package of the flagship platform — the same Speed Sniffer nose cone, narrow aero seatpost, and Rider-First Engineered™ geometry — built around Specialized's 10r Carbon layup as the accessible entry point into the SL8 range. A 68mm threaded bottom bracket, flat-mount disc brakes, and simple, no-hassle cable integration make it an ideal starting point for your own dream build.
Key Highlights
- Aero where it matters: the Speed Sniffer nose cone and a narrow, UCI-legal aero seatpost make the SL8 platform Specialized's most aerodynamic road frame yet — more aero than the Venge.
- FACT 10r Carbon construction: the accessible entry point into the SL8 platform, sharing its aero shaping and Rider-First Engineered™ geometry with the S-Works-level frame, at a claimed 685-gram frame weight (size 56).
- Stiffer, more compliant ride: up to 33% more stiffness-to-weight than the Tarmac SL7, with roughly 6% more in-saddle compliance for a smoother ride on rough roads.
- 32mm tyre clearance: the same proven geometry as the SL7, with room to size up for comfort or rough-road versatility.
- Complete custom-build canvas: includes the matched FACT 10r Carbon fork, S-Works Tarmac SL8 Carbon seatpost, and integrated stem, ready for your own groupset, wheels, and finishing kit.
