Specialized Tarmac SL4 Road Bike 2018
The Specialized Tarmac SL4 Elite Road Bike combines durability and velocity, to form a well-rounded, do-it-all machine at a competitive price point.
Utilising the same geometry and FACT 9r carbon fibre construction as the Grand Tour winning bikes, ridden by athletes such as Peter Sagan, no-one can question this bikes capabilities. The high grade carbon helps ensure the bikes low weight, whilst increasing it's compliance and ride quality by damping unwanted road feedback and reducing flex, for a stiff, fast ride every time.
Add the S-Works FACT carbon, full monocoque, tapered fork into the mix, and the performance is perfected. Further reducing vibrations transferred to the riders wrists, comfort is greatly increased, making longer days in the saddle more bearable. Additonally, the tapered design greatly increases front end stiffness, resulting in the direct, responsive steering required to succeed in a race environment.
The drivetrain is made up of a mix of Praxis Works and Shimano components, two extremely highly regarded brands, coming together to form the perfect balance of perfomance, durability and value for money. Utilising Shimano's Ultegra 6800 11-speed shifters and mechs, shifting is crisp and effortless, whilst the matching Ultegra brakes ensure controlled and responsive stopping power, for a confidence inspiring ride. The Praxis Works 50/34t chainset and Shimano 105 11-28t cassette offer a wide gear range, equally as suited to spinning up mountainous climbs, as it is sprinting away from the bunch on a flat, open circuit.
The bike is finished with Specialized's own parts, offering high levels of durability and performance. The Axis Elite wheels thrive in blustery conditions, thanks to their low profile design, whilst the Comp carbon seatpost and Toupe saddle combination further increase comfort levels, ensuring this versatile bike is your companion of choice, regardless of the gradient or distances up ahead.
