The Tarmac SL9

There isn’t much information on the frame yet. Some redditors are claiming this is a planned release to hype it up, while a Specialized Staff member claims the image is fake. I would expect an official release of the bike around the time of the Tour de France.

Specialized has been on a 3–4-year cycle with the release of the Tarmac (full breakdown of the Tarmac releases below). Though, there was a shorter time span between the SL7 to SL8 because the SL8 was the combination of the SL7 and Venge into a single bike.

The main difference appears to be UDH, redesign of the fork, and a more aerodynamic seat post. the seat tube has a more curved shape similar to bikes 10 years ago. it seems like they are reduced the size of the head tube, but maybe that is just optics due to the fork being flush.

I currently ride an SL7 regularly and it has been a fantastic bike. If you are looking for a new bike, the SL9 is going to be a good option, or pick up an SL8 once the SL9 is released.

The Tarmac launched in 2003 as Specialized’s flagship road racer. It started as the E5 (hybrid aluminum/carbon frame with an arched top tube) — stiff and light but famously harsh.

2006: SL1 — First full-carbon Tarmac (FACT carbon). Smoother ride; developed with input from Tom Boonen.
2008: SL2 — Major step forward with size-specific tube profiles and rear-stay redesign for balanced stiffness + comfort across rider sizes (early Rider First Engineering).
2010: SL3 — ~150 g lighter and stiffer; powered Andy Schleck’s Tour de France win.
2011: SL4 — Further stiffness-to-weight gains, refined head tube/fork, and one-piece chainstays.
2015: SL5 — First disc-brake version; formalized Rider First Engineering with size-specific layups.
2019: SL6 — Big aero leap (dropped seatstays, D-shaped post) while shedding weight; borrowed Venge aero tech.
2021: SL7 — Disc-only; combined the best of Tarmac + Venge into Specialized’s “one bike to rule them all.” Significantly faster aerodynamically.
2023: SL8 (current) — Lightest yet (685 g claimed S-Works frame), highest stiffness-to-weight, improved front-end aero (“Speed Sniffer” nose), and better compliance while keeping 32 mm tire clearance.

Over 20+ years the Tarmac evolved from a pure climbing/race bike into today’s balanced aero-lightweight all-rounder that still dominates pro racing. The core geometry has stayed remarkably consistent since the SL2 era.

Specialized drives cycling innovation through a rider-centric, data-driven philosophy that blends performance, comfort, and accessibility. Its Rider-First Engineering ensures size-specific frame layups and geometry for consistent stiffness, handling, and ride quality across all sizes, while Body Geometry—developed with medical experts—uses 3D-printed Mirror saddles and ergonomic contact points to reduce injury and boost power.

Aerodynamically, the brand leverages supercomputer-generated FreeFoil shapes and wind-tunnel testing to create bikes like the Tarmac SL series, which seamlessly merge low weight, high stiffness-to-weight, and speed without sacrificing compliance. In e-bikes, Specialized leads with OTA software updates (e.g., boosting Levo power), touchscreen integration, and digital features in models like the Turbo Vado, all while advancing sustainability and materials tech after 50 years at the industry forefront.
