Product Description

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 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 our fan-favorite Power saddle.

For the construction of the Tarmac, we utilized advanced aerospace composite optimization software to revolutionize the construction and layup of our new FACT 10r carbon. It's the most schedule, we've ever made and this allowed us to shed nearly 200 grams. That's right, a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.

500 pieces creating 7 different sizes with the same tuned ride–that’s Rider-First Engineered™. We examine every ply of carbon on every frame size to ensure that all of our performance targets come through. 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.

Aerodynamics is the most important thing we can do to make you faster, but with the Tarmac, we added aero features without any cost to weight. Through development, three areas were discovered where we could add aero for free—a new fork shape, dropped seatstays with aero tubes, and a D-shaped seatpost and seat tube. The result? A Tarmac that’s approximately 45 seconds faster over 40 kilometers.

The updated the geometry is based on countless Retül data points and professional rider input. This enabled us to develop a Performance Road Geometry that perfects the combination of a responsive front-end and short wheelbase, which delivers instantaneous response and optimal power transfer.

For additional compliance, the seatpost has flex built-into the upper 120mm where clamping doesn't happen. We also dropped the seatstays, altered the seat tube shape, and added tire clearance up to 30mm.

Occasionally, without notice, manufacturers change product design and/or specifications.

Road Bike Guide

Is a Road Bike Right for Me?

If you’re new to the cycling world, we highly recommend taking a look at our bike buying guide overview or our road bike buying guide to help you decide what type of bike is right for your needs.

When you’re choosing a road bike, there are a few things to look out for which can help you work out the quality and performance you can expect from a particular model.


Usage

What road bike is right for you? There are a few different kinds of road bike, and they all have their specialities. We break down their strengths and usage in an easy to read table below.

Type of Road Bike

Usage

Pros

Cons

Sportive Road

Long distance, training, sportive and endurance riding, as well as rough roads.

Comfortable, relaxed geometry is more accessible for riders new to road cycling.

Not as aggressive or stiff, so serious racers may look for a road race bike.

Road Race

Racing and training.

Lightweight, aggressive geometry for most efficient riding position.

Range limited to tarmac roads and cycle paths.

Aero Race

Road and criterium racing.

Aero dynamically efficient and fast. Stiff frames and aggressive geometry.

Heavier than road race bikes.

Flat Bar Road

Training and commuting. Comfortable, fast city riding.

Upright riding position is great for training and city riding.

Limited options of bikes. MTB-like position not great for racing.

Frame Material

The vast majority of road bikes are made from either aluminium alloy or carbon fibre. Alloy bikes can offer higher tier groupsets for a lower price, whereas carbon frames come at a significant premium, but are lighter and give that extra performance advantage.

Aluminium

Aluminium alloy frames
Alloy frames have come a long way recently, using hydroforming and butting to keep the weight low, while keeping stiffness high.

Carbon fibre

Carbon fibre composite frames
Carbon frames have a lighter weight and greater stiffness, while maintaining excellent comfort.


Fork

Road bike forks are made to be lightweight and stiff, giving accurate steering, as well as a comfortable ride. Budget road bikes will have alloy forks, whereas mid-range forks often have mix-material forks, with alloy steerer tubes and carbon fork blades. Carbon bladed forks deliver a more comfortable ride, absorbing road vibrations and flexing slightly in rough roads. Full carbon forks are found on high end road bikes. They are especially lightweight and offer even greater stiffness.


Groupset

A bike’s groupset, or drivetrain, is where the biggest difference in component quality is seen. A complete groupset comprises of the following parts:

  • Chainset (aka Crankset)
  • Bottom bracket
  • Brakes
  • Brake levers
  • Shifters
  • Front & rear derailleur
  • Chain
  • Cassette

Road groupsets are supplied by Shimano, SRAM or Campagnolo. Having reliable and fast shifting can make all the difference when pushing hard. The majority of road bikes have double chainring drivetrains, while triple chainring setups are usually only found on low end bikes and touring bikes. Road bikes will have 7-11 speeds in the rear, with higher gears meaning more options for smoother riding.

Road Groupsets

Brakes

Disc Brakes

Disc brakes
Disc brakes offer greater stopping power and modulation. They work as well in wet as dry weather, and don’t require the rims to be replaced periodically. They come at a weight penalty, however.

Calliper Rim Brakes

Calliper rim brakes
Rim brakes are lightweight and easy to maintain. They allow greater aerodynamics for aero road bikes and


Wheels & Tyres

Types of tyres

Road bikes tyres don’t vary as much as mountain bike or even hybrid, but they still make a huge difference to how the bike rides. For a detailed look into road bike tyres, see our guide.

Road tyres have long been offered as either clincher or tubular. Clincher tyres are the standard tyres that fit onto standard rims with a tube holding the air. Tubular tyres are glued to a special tubular rim and are fully encased, doing without a tube.

Tubeless tyres are now a feature of road bikes, delivering a compromise between tubular and clincher tyres. They look the same as clincher tyres, but pair up with special rims to offer a proper seal within the tyres, also doing away with tubes.

Tyre Size

Road tyres are traditionally quite narrow. Nowadays the accepted standard is 25c, but 23c and 28c tyres are very common too. The larger the size tyre, the more comfortable they will be, but they will also be heavier and potentially slower rolling. Sportive and flat bar road bikes will commonly have wider tyres, whereas race and aero road bike will tend towards narrower tyres.
