Product Details

Cervélo R3 Ultegra Di2

Combining the Paris Roubaix-proven Cervélo R3 frame design with equally smooth Shimano Ultegra Di2 shifting gets you closer to that ideal - a bike that practically rides itself.

  • Full carbon frame with compression-moulded carbon dropouts save weight with no sacrifice in strength.
  • The tapered fork increases head tube stiffness for improved handling.
  • Squoval combine the attributes of square and oval shaped tubes to achieve an ideal balance of stiffness, light weight, and aerodynamics.
  • Redesigned leading edges combine with reoriented seat stays reduce air drag by 7 watts compared with previous generation R3.
  • Future-proof cable management allows easy interchange between mechanical and electronic shifting, and cable and hydraulic shifting.
  • Cervélo's unique asymmetric BBRight bottom bracket shell is oversized on the non drive side to maximises power output.
  • The BBright bottom bracket increases stiffness and reduces frame weight while allowing for a large range of crank compatibility in a modern press fit system.
  • 2015 BBright boasts 8% stiffness increase at bottom bracket vs previous R3.
  • Exceptional record in World Tour classics - on the podium at Paris-Roubaix six times in seven starts—with three victories

Shimano Ultegra Di2
Electronic shifting is now so established at the cutting edge of cycling - professional road racing - it's now as ubiquitous as clip-in pedals and Lycra.

If you're looking for the quickest, most accurate gear shifting system that's also the easiest to keep in perfect adjustment, electronic shifting is the way to go, and Shimano Ultegra Di2 is established as the most proven and most affordable set up.
Replacing the traditional mechanical cable with an electric cable eliminates poor shifting caused by kinks, corrosion and stretching, and guarantees effortless gear shifts - just as good hydraulic (cable-free) brakes have revolutionised mountain bike (and more recently road bike) braking performance.

Changing gear with fingertip-actuated Ultegra electronic shift buttons is easier, faster and more accurate than you ever experienced before with 'acoustic shifters'. As Shimano so eloquently put it, 'just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear'.

The Benefits of Pre-Built 'System Wheels' such as the Mavic Aksium S

Whether you are looking for more immediate flex-free power transfer, bomb-proof quality or super light weight, fitting a set of system wheels is one of the most profound improvements you can make to a bicycle.

For over a hundred years, the ability to build a bicycle wheel tight, strong and true has been rightly regarded as one of the pinnacles of the bicycle mechanic's craft. If you want your choice of rim, hub and spokes hand built for you into a wheel you can rely upon for years and years, our Service Centres(we have one in every branch) will be delighted to oblige.

Since Mavic pioneered complete 'system wheels' in the 1990s (followed by companies such as Shimano and Fulcrum) superior bicycle wheels have become readily available off the shelf.

The benefit of a system wheel is that the manufacturer can design the best wheel possible at that price without being obliged to make any compromises. (Compare this with the situation where, say, Mavic make a rim, they have to second guess how it will work with the vast array of spokes and hubs on the market.) With a wheel system, the manufacturer takes complete control of all the elements that go into the creation of a quality wheel - lacing pattern, spoke count, spoke thickness, spoke tension, rim width, hub flange size....

Furthermore, they can integrate the drilling patterns of both the hub and the rim with the bend and thickness of the spokes to ensure each spoke nestles perfectly in place and thus minimise stress on the spoke holes. Designing the rear wheel from scratch enables offset spoke lacing patterns that minimise 'dishing', and hence creates a stronger wheel. The manufacturer can reinforce the hub and rim or shave weight where appropriate depending whether the wheel is going to be used with a rim or a hub brake. They can create a complete range of wheels from the lightest weight to the absolute strongest with numerous options in between.

The end result is a wheel that you can argue is 'beyond hand built' quality yet, thanks to the economies of scale enjoyed by companies such as Mavic, Fulcrum and Shimano, one of these system wheels need not be significantly more expensive than a hand-built wheel made with a similar quality hub, rim and spokes.

'The R3 features BBright and the same exclusive second generation Squoval tube shapes as the R5, to combine all the benefits of a stiff and light bicycle with the strength and comfort needed to win on the cobbles of the roughest roads in Europe. Built on the lessons learned at Project California, its renowned comfort comes from using ultra-thin seat stays along with an optimized 1 3/8”steerer tube. Stiff, light and comfortable, this bike provides the responsiveness and the confidence needed when descending, cornering, racing for the win, or just sheer pleasure during your Sunday ride.'
