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.
A BIKE THAT PUTS YOU FIRST
Rider-First Engineered
ALL THE STOPPING
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.
YOU’VE GOT THE POWER
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:
When you think of the seat tubes of a 49 and 61cm Tarmac, there’s a size difference, sure, but you probably don’t know that different materials were used to make them. And actually, this is true throughout the size range. For example, the ply that reaches from the bottom bracket to the top tube on a 61cm uses a thicker, stiffer carbon fiber than what’s used on, say, a 49 or 56cm frame. This ensures that both big and small riders will feel just the right amount of seat tube deflection, which’ll save your back and posterior on long, hard days in the saddle.
