New model comes with a claimed frame weight of just 850g

Fresh from launching the R3 Disc earlier this year, Cervelo has unveiled its first ever range of endurance bikes: the C-Series, with the Cervelo C5, the top model in the new range, claiming to have the lightest endurance frame currently on the market.

This is a bike that has been designed specifically for sportive and gran fondo riders, who want long distance comfort without sacrificing speed, and interestingly will only be available with disc brakes with no options available for riders who favour caliper brakes.

So what are the main features of the new Cervelo C-Series that the Canadian company thinks will make it such a big hit.

Well clearly, comfort is a major factor in any endurance bike. To ensure that this is a comfortable bike, Cervelo has given it attractive curved seatstays, which also look incredibly thin, in order to soak up vibrations from the back end. It also has a shorter reach than the R-series (352mm compared to 357mm for the 56cm model), meaning a more upright ride position.

This focus on comfort is also reflected in the bike’s handling. According to Cervelo, dropping the bottom bracket helps to lower the bike’s centre of gravity, meaning more stable handling through the corners, while the wheelbase has also been extended to give the same effect thanks to increased fork rake, lengthened chainstays, and a shallower head tube angle.

However, despite all that talk of comfort, Cervelo is keen to stress that this this bike has a performance edge too. This is thanks to the Squoval 2 tube shapes, the same as used on the brand’s R5CA superbike, which claim to marry lightweight, stiffness and comfort with their superwide design.

The new Cervelo C-Series is ideally suited for long rides

The final headline with the Cervelo C-Series is the focus on disc brakes. The frame has been designed with disc brakes (and more specifically, flat-mount disc brakes) in mind, with a single-piece rear triangle and wider angled seatstays in order to accomodate the calipers and rotors. The new bike will also use thru-axles at both front and rear.

The Cervelo C-Series will be available in seven different options. The higher end Cervelo C5 will be the first to roll off the production line, with availablility set for January. This top-end bike will be available as frameset-only (£3,799), or in two full builds with Shimano Dura-Ace Di2 (£7,499) or Dura-Ace mechanical (£6,199). Both will be matched with HED Ardennes Plus LT wheels and Shimano hydraulic disc brakes.

You’ll have to wait until March for the slightly more affordable Cervelo C3, but you do get one extra build to choose from. As well as the frameset-only option (£2,199), you can have either Shimano Ultegra Di2 (£4,999), Ultegra mechanical (£3,899), or SRAM Force 1 (£4,599), all of which come with HED Ardennes GT+ wheels and either Shimano or SRAM hydraulic disc brakes.

We’ll be contacting Cervelo for a test bike for review as soon as possible.
