Specialized Tarmac SL4 Comp Di2 2014 Road Bike. With its race-optimised, FACT carbon frame, efficient handling and increased 19% stiffness-to-weight ratio over the previous Tour de France-winning version, the Tarmac SL4 has plenty of Pro-Tour proven speed up its sleeve. Simply put; nothing is lighter and stiffer. That's why it's the go-to choice of the pro peloton. Ride it hard, ride it fast, just wind yourself up and go.
Specialized SL4 FACT 9r carbon frame with uniquely shaped, tapered headtube and OSBB is now even stiffer and lighter for pure, unbridled speed and power; paired with tapered, full-monocoque FACT carbon fork for ultimate steering precision. Specialized Turbo Elite 23c tyres roll like a racing tyre, but offer incredible durability and puncture resistance through BlackBelt protection. FSA Gossamer Pro BB30 with race-compact gearing delivers excellent power transfer and consistent shifting. New Shimano Ultegra Di2, 11-speed electronic drivetrain delivers predictable, precise shifting under any conditions. With astounding light weight, it's one of the finest parts kits available. Specialized Comp FACT carbon seatpost offers the exceptional vibration damping characteristics of carbon fibre for long days in the saddle.
