When we developed the Tarmac Disc, we didn't just want it to be fast. We wanted it to be fast everywhere. Long climbs, windy flats, Grand Tour stages, local fondos—we built a race bike to be the most complete out there. How’d we do it? We started with our Rider-First Engineered™ frame with a perfectly-tuned ride quality for every size, added in some serious aero tech that makes it 30 seconds faster than the Tarmac SL5 over 40 kilometers, and then made it 20% lighter. Nothing is lighter, faster, and better handling. This Tarmac comes with a reliable spec that includes 10-speed Shimano Tiagra mechanical shifting, quick-stopping hydraulic disc brakes, durable Axis Sport Disc wheels, and our fan-favorite Power saddle.
