The all-new Specialized Allez Sprint Frameset takes inspiration from the Tarmac SL7, rebuilt in alloy using Smartweld technology. Combining innovations from its carbon sibling with a precision-engineered aluminium frame, the Allez Sprint redefines what an alloy bike can be.
Equipped with a Tarmac SL7 FACT carbon fork and seatpost, the frameset is compatible with both aero and traditional stems and bars, as well as electronic and mechanical drivetrains. A threaded bottom bracket ensures easy maintenance and reliability, leaving riders free to build their dream alloy superbike.
The Allez Sprint is the fastest alloy road bike ever, thanks to lessons learned from the Tarmac SL7 in the wind tunnel. Integrated cables and the most advanced alloy head tube Specialized has created make it 41 seconds faster over 40 km than the previous generation. A hydroformed one-piece bottom bracket and downtube deliver ruthless pedalling efficiency with outstanding stability.
Dropped seat stays, paired with the carbon fork and seatpost from the Tarmac SL7, add comfort and compliance while maintaining precision at the bars. Championship-proven geometry ensures sharp handling, stability on descents, and comfort for long rides, making the Allez Sprint as capable as it is fast.
At the heart of the Allez Sprint is Smartweld technology. Hydroformed tubes and the most complex alloy head tube ever built are joined with unmatched precision, creating the first true alloy superbike that balances aerodynamics, power transfer and confident handling.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.
The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
