This is the next generation of aero road bike from Cervélo. Named the S5, Cervélo has jumped over the O4 version so it takes up where the S3 left off.

Regular Cervélo admirers will already understand the design language the Canadian frame manufacturer has used, as it borrows much from the P4 time trial machine.

The most obvious lift is the seat tube, its close fitting and a proper ‘cutout’ but still uses a vertical drop out for easy wheel changes. At both ends of the seat tube the frame also mimics the P4 with a dual head seat post and whopping bottom bracket.

The headtube has also seen a lot of work with the downtube junction effectively being dropped down to the crown – check out the limited space between the tyre and the downtube, Cervélo says that it’ll still run a 25c but our guessing is it’ll be a close-run thing.

The down tube has also been altered so that the lower half is a truncated aerofoil or Kam tail to reduce drag around the bottle. Two bottle mounting points also feature on the down tube, the lower pair of holes of the three for a single bottle and the upper pair if you plan to run a second bottle on the seat tube.

Even the seat stays have been looked at and the joint between them and the seat tube shows a real attention to detail – it’s very sleek.

Three frame models will be available in the UK; the S5 VWD £3999.99, S5 Team £2999.99, and a vanilla S5 for which the price has yet to be set.

The version you see here is one of ten limited edition bikes that has been delivered to key UK Cervélo dealers who’ll be displaying it during the Tour.

This limited edition Team model will then be for sale; it’ll weigh in at six grand.

    I disagree partially with Katie and gatotten, even though I appreciate their point of view. You are correct in saying that the cyclist ( the motor ) is the most important aspect of cycling. But advancement in frame designs/ materials are not gimmicky.. I can appreciate that bike manufacturers will want to role out new designs every year to boost sales. But most of the manufacturers out there are trying to increase the efficiency of your riding aswell. As we are on the topic of the S5, will use that as an example, if you read the White paper that is basically the design technical concept description of the bike you will see that the aero performance over the S3 is quite considerable… The S3 was already knocking the socks off everyother bike in the market in terms of aerodynamics. I suggest you sceptics have a look at the paper, especially the Kilowatt saving over a 40 mile ride, and the time saving over a non aero bike on a 40 mile ride from my memory was 1min30, if you had the same cyclist on a non aero bike putting in the same power. Its interesting to see lots of manufacturers following suuit with Cervelo and bringing out aero bikes like the specialized venge, the new Parlee, the Ridley Noah etc… I know there are alot of people that will buy these bikes for the bling factor, but some people do want the real life gains… like myself..
    As is with cycling, it depends how seriously you take it, and how much of a clock watcher you are. Sounds like I work for Cervelo here ha ha, but I also think the bike is good looking, not in a classical bike shape. Wouldnt say its as attractive as my Bianchi but I wouldnt just ride it at night…
    The good thing about cycling is even if a noob buys all the best aero/light bike kit, they still get burned by the more experienced riders who have been training their bodies for years. No short cuts in this sport…..
    p.s. I think Scott Taylors right, disc brakes will be the next big thing on road bikes, in particular for people with carbon rims,as braking on my carbon rims can be poor in certains conditions even with cork/swissstop yellow and you have the damaging the rim factor also….

  • gatotten

    I agree with Katie. It’s the motor (cyclist) not the bike. It’s a gimmick. I had a friend that bought a custom $4,700 FRAME ONLY. He couldn’t hang with me on my $10 1972 Schwin yard sale bike!

    Greg, sloping top tubes were on the go long before sportives. Giant have been doing them for approx 15 years – Just like many other design ‘innovations’ on road bikes like external bottom bracket shells, a-head set, integrated brake/gear levers, rear cassettes/freehub bodies and bolt on stems they came from the MTB market. Next big thing on road bikes in my opinion will be disc brakes.

    Re the Cervelo, not one for me personally and I doubt it would be comfortable on long rides or sportives. I’ll stick to my Look.

  • Greg

    And there I was thinking that sloping top tubes were for the ‘sportive market’.

  • Bfg

    Normally I like Cervelo frames but there is nothing normal about that thing. It must have hit every carbon branch on the ugly tree.

  • Paul G

    Reminds me a bit of the Felt AR bikes, but not as aesthetically pleasing by any standards… I’m sure it’s excellent, but i doubt i’d get one personally.

  • beev

    i think the sloping top tube is the most challenging aspects of its design/looks – the coloured stripes do little to help in the looks department also. will be interested to test it though – and see whether it really could be the “only” bike you would ever need – ie to train, and for road + tri….

  • PeterLB

    Jeepers, that is one hideous looking bike.

  • Nick Rearden

    Robert, I expect they’ll do other colour options in line with their usual range. To be fair to them, Cervelo do some of the more imaginative and, dare I say it, ‘tasteful’ schemes but launch models are nearly always controversial to attract maximum attention.

  • katie

    Have you ever thought that if you add up in time/ Km of all the claimed advantages for the re-designing of equipment to make it more aero then we should be getting towards the faster than the speed of light scenario
    How many of us still struggle to beat the hour for 25 miles in spite of this and you think when did Alf Engers achieve the 30MPH barrier and look at his bike compared to the all singing and dancing machines we ride today.
    Is maybe all this sudden revisiting the design board and understanding aerodynamics not just becoming a marketing blurb designed to make us buy new every year.
    You only have to look each week at highly desirable top of the range bikes being sold seconhand in the Cycling pages where it states things like only 20 dry miles since new to realise that people shell out megabucks in the hope that they will become superstars to then find out in spite of the manufacturers claims that Cycling is still hard work and the old addage of “:no gain without pain” still applies

    Ok I’m down with aero and all but the color is hideous. Most of us can’t hide are bikes in a peleton on a daily basis so how about something not so fugly besides red and blue ?
