Product Description

5/5 BikeRadar “The Roubaix's comfort, control and handling qualities are among the very best”

road.cc - Sportive and Endurance Bike of the Year 2017-18

Expand your riding horizons to even the very roughest roads, on the Specialized Roubaix Expert Ultegra Di2. This endurance road bike features cutting edge frame and component technology to offer a smoother and faster ride on every road.

Specialized developed the Roubaix to race over the challenging road surfaces that are found on Spring classic races, like the iconic Paris-Roubaix. The lightweight FACT 10r carbon frame is made to go the distance, and is extremely capable on rough roads.

With the Future Shock, Specialized has taken comfort and control to the next level in road racing. Developed with the help of McLaren Applied Technologies, Future Shock is a suspension cartridge inside the headtube with 20mm travel working between the stem and frame. It effectively isolates much of the bumps from your hands, allowing the bike to maintain the same momentum. It’s particularly good for rough roads.

Paired with the Future Shock, the seatpost features rearward arc compliance that leaves room for the seatpost to flex slightly inside the frame, reducing vibrations and bumps from filtering to the saddle.

The Rider-First Engineered™ technology that Specialized use to build their frames takes into account people of all sizes, making each size of the bike ride with exactly the same characteristics, so everyone gets the same fantastic experience. The rear of the frame has a thru-axle and 12x142mm spacing, keeping it stiff and responsive. The FACT carbon fork is lightweight and stiff, especially with its 12x100mm spacing and thru-axle, allowing extremely precise steering.

Nothing shifts like Di2. The Full Shimano Ultegra Di2 electronic drivetrain features a compact chainset, and wide range cassette, and is ideal for taking on the varied terrain you find on long distance routes. Ultegra hydraulic disc brakes offer refined stopping control in all weather conditions.

Ride the future today, on the Specialized Roubaix Exert Di2.

Comfortable and super-quick!

Having owned a Specialized Roubaix previously, I thought generally knew what to expect from the range; but I was wrong. The 2018 Roubaix is twice as comfortable as the pervious ‘Zert’ era and the Future Shock really works to smooth things out (you will not notice any travel in the ride) and boy, it’s fast, proper ‘Tarmac’ fast. You don’t certainly need the cobbles to benefit from the ride, but I’m finding that keeping the Garmin tightly attached to the bars a struggle as the Future Shock constantly tries to throw it off. The disc brakes pretty much saved my life in the first wet outing, so I am an instant fan, and if you’ve never tried Di2 you will be in love from minute one (I’m certainly never going back). The seat looks great, but I instantly swapped it out for an ISM as I’m a sucker for comfort. Finally, I need to commend Tredz and their excellent delivery and communications. It’s certainly true that if you go to Specialized directly you do can a few extra bells and whistles (such as a new fit if you need), but in terms of speed of delivery you cannot beat Tredz. 100% perfect service and delivery that I cannot fault in any way (thank you Tredz!). Buy the 2018 Roubaix, you will not be disappointed!

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.
