A meticulous innovation of Specialized’s engineering in the aero bike world that has spanned two decades and eight generations, the Tarmac SL8 Expert Ultegra Di2 Road Bike is a testament to the advances made in aerodynamics, weight-saving and ride quality. Dubbed Specialized’s fastest race bike ever – going as far as 128 seconds faster on the Milan San Remo race, this road bike has been expertly designed and developed to craft an uncompromising combination of compliance, stiffness, lightweight and aerodynamics through its newly developed “Speed Sniffer” nose cone that improves the leading edge of the head tube to be much sharper, slicing through the air without the drag, paired with their narrowest, most aerodynamic seatpost that ensures air around the legs flows back far more cleanly.

With a 685g carbon frame that is 15% lighter than the SL7 and continues to efficiently carry loads with impressive stiffness, the SL8 exhibits only the best in its legendary handling, aggressive responsiveness and World Championship-proven geometry. You’ll experience 6% more compliance whilst in the saddle stemming from the stiffer pedals and more precise control at the handlebars, and the geometry, having been proven to be world -class, is identical to the SL7 and so offers a tyre clearance of up to 32mm for those days when higher volumes are required.

The full Shimano Ultregra Di2 groupset engineered for speed and efficiency is offset with hydraulic disc brakes to maintain stopping power throughout all weather conditions from dry, sunny days to those periods where the roads are slick with rain and with Specialized’s Rider-First Engineering, every rider regardless of their size will experience the same unhindered, unprecedented ride quality. Speed has never come to you easier with the latest in Specialized’s aerodynamics innovations, the Tarmac SL8 Expert Ultegra Di2 Road Bike.

Features: 

• Dubbed the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo and 20 seconds faster than the legendary Tourmalet climb
• Speed Sniffer nose cone: by moving the steer tube back (that determines the head tube width), the leading edge of the head tube can be much sharper, delivering much lower drag
• Utilising new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post, ensuring dirty air around the legs can flow back more cleanly
• 685g frame is 15% lighter tha the Tarmac SL7 and the frame's shape carries load so efficiently that extra carbon stiffness layers become redundant
• An improvement on stiffness-to-weight of 33% over the Tarmac SL7, the SL8 exhibits legendary handling, aggressive responsiveness and World Championship-proven geometry to the next level 
• Stiffer at the pedals, more precise at the bars and combines it with a compliant ride in the saddle for next-level race comfort
• In the saddle, the SL8 gives 6% more compliance and the proven geometry with 32mm tyre clearance are identical to the SL7, ensuring easy adaption and versatility to run higher volume tyres when needed
• Beyond Gender: built to accommodate every rider without outdated gender specific models
• Full Shimano Ultegra Di2 groupset, C38 carbon tubeless ready wheelset and an SL7 stem with a Specialized Expert Shallow Drop alloy handlebars makes for an accessible performance-packed bike
• Weight (size 56): 7.18kg / 15lbs, 13.3oz
