Specialized S-Works Tarmac SL8 (custom build) - 2025, 52 cm
The 2025 Specialized S-Works Tarmac SL8 represents the pinnacle of road racing technology, and this custom 52cm build takes that performance to a more specialized, aerodynamic level. Constructed from the premier FACT 12r carbon, the SL8 frame is designed to be the fastest race bike in the world by combining aero-efficiency with a sub-700g frame weight. This specific machine is presented in a pristine mint condition, finished in a timeless satin carbon and white colorway.
The heart of this custom build is a SRAM Force E1 AXS 1x drivetrain. By utilizing a single 48T Aero chainring and a 10-36T cassette, this setup provides a massive gear range while reducing weight, mechanical complexity, and aerodynamic drag. Performance tracking is seamless via the factory-integrated SRAM AXS power meter. Notably, the bike utilizes 160mm crank arms, a preferred choice for modern riders looking to optimize hip angle and pedal clearance.
The cockpit is a masterclass in lightweight integration, featuring the Roval Alpinist SL one-piece bar and stem (110mm x 400mm). This is complemented by CeramicSpeed SLT bearings in the headset, ensuring smooth, maintenance-free steering. The bike rolls on Roval Rapide CLX carbon wheels—the winningest wheels in the pro peloton—wrapped in high-volume 31mm ENVE SES tubeless tires for an unmatched balance of speed and vibration damping. Complete with an S-Works Power Mirror saddle, this Tarmac SL8 is a no-compromise race weapon ready for the highest level of competition.
