Though it may have been the peloton’s worst kept secret, the 2018 Tarmac Disc is finally here. Rider First Engineered, 45 seconds faster and now with disc brakes, Specialized’s most complete race bike just got that little bit … well … more complete.

If you want to go fast, like go fast everywhere, this is the bike. This is the bike that’s made for everything from Grand Tours to your local fondo, and with a ground-up redesign, a heavy dose of aero wizardry, and of course, disc brakes.


Rider-First Engineered

Seven different sizes with the same tuned ride. The only way to do this is to obsess over every carbon ply and arrangement. It isn’t the kind of glamorous work that lands you on the cover of magazines. Nope. It’s scientists scrutinizing every thickness and shape, having heated arguments over stiffness targets and handling prowess like a model UN, but you’d never notice that when you’re riding a Tarmac. You’ll just feel like you’re riding the perfect bike.


Options—Specialized want you to have them. That’s why there is a rim brake Tarmac and a disc version. No matter your preference, you’re covered. And better yet, the two versions are evenly matched on aero performance, speed, and handling, so your choice is really left to what you like and not what you’re willing to sacrifice.


Introducing the lightest and most accurate power meter on the market; the all-new S-Works Power Cranks. An outlandish claim you may say, but Specialized have been able to achieve this through combining the incredibly light and stiff, carbon fiber S-Works road cranks with dual-sided power measurement, making it the lightest (440g/172.5mm) and most accurate power meter available.

No One Else Would Go to This Length

We literally examine every ply of carbon on every single frame size we make to ensure that all of our performance targets come through on the finished product. The process is absurdly detailed, because what works on a 49cm doesn’t work on a 61cm. So, to make sure you get the perfect ride, every frame gets a unique layup schedule with different ply arrangements, orientations, quantities of material in specific areas, and sometimes, even exclusive thicknesses and types of carbon itself.

Below, you’ll find just a few of these places where this dark magic is applied:
