Specialized Tarmac SL6 Sport Disc Road Bike 2019

The Tarmac family is renowned within pro cycling for delivering a unique blend of precision handling, featherlight weight and an incredible stiffness profile, and the Tarmac SL6 Sport Disc Road Bike is no different. By combining a high-grade carbon fibre frameset with a reliable specification full of top-quality components, this bike delivers top-end performance at an impressively accessible price point.

At the heart of this bike is a high-grade FACT 9r carbon fibre frame paired with a FACT 10r fork. Together, this provides an extremely lightweight frameset perfect for climbing, with tube shapes relentlessly optimised to provide a sector-leading stiffness profile. Specialized's Rider-First Engineered™ technology, meanwhile, ensures that every single frame size brings the same legendary climbing responsiveness that you'd expect from a Tarmac. The thru-axle specific frameset, helps add to the overall stiffness and efficiency of the ride.

The 11-speed 105 groupset provides extremely reliable and slick shifting performance, while the hydraulic disc brakes guarantee powerful stopping power in all conditions - even wet weather. The ever-popular 105 groupset has recently received a comprehensive update, and this new R7000 series now boasts many of the same performance features that were previously the preserve of Shimano's top-tier groupsets.

The bike is rolling on a set of dependable and long-lasting DT R470 Disc wheels, which are shod with a pair of Turbo Pro tyres in a comfortable 26mm width. The seatpost, meanwhile, is made from FACT carbon in order to provide that extra touch of riding compliance. The package is nicely rounded out with Specialized's in-house touchpoint components for a comfortable ride.


  • Featuring Specialized's Rider-First Engineered™ design that ensures every frame size has the same legendary climbing responsiveness and descending prowess you'd expect from a Tarmac. The FACT 9r frame is the perfect blend of value and performance.
  • The 11-speed Shimano 105 shifting is extremely reliable and precise, while the hydraulic disc brakes offer exceptional modulation and stopping power.
  • DT R470 Disc wheels feature reliable, sealed cartridge hubs, and 24 front and rear spokes that keeps weight low and durability high.
