The 2020 Specialized Tarmac SL6 Disc Expert was created to be fast everywhere. Long climbs, windy flats, Grand Tour stages, local fondos—Specialized built a race bike to be the most complete out there. How'd they do it? Specialized started with a Rider-First Engineered™ frame with a perfectly-tuned ride quality for every size, added in some serious aero tech that makes it 45 seconds faster over 40 kilometers than the Tarmac SL5, and then made it 20% lighter. Nothing is lighter, faster, and better handling. The build spec on this Tarmac Disc is value-packed, featuring Shimano Ultegra Di2 electronic shifting and hydraulic disc brakes, a Roval C 38 Disc carbon fiber wheelset, S-Works Turbo tires, and the fan-favorite Power saddle.
