4 out of 5 stars

"Insane cost and controversial sportive shape, but a sublime mix of ethereal weight, electrifying responsiveness and efficient comfort"

Sun 11 Sep 2011, 9:00 am BSTBy

Cervélo’s £3,500 R5 frame is already one of the lightest, stiffest, most innovative and most prestigious road frames available. However Cervélo’s own design engineers hand-build this limited-edition Project California (Ca) to take their design and tech skills to the limit. Can it be worth £7,500 just for the frame and fork?

Given its murdered aesthetics and cost-no-object price tag we were shocked by the longhaul comfort slant of Cervélo’s R5Ca, but considering those who will buy it, it’s also a smart choice. Its ethereal climbing efficiency, surefooted descending and sublime fatigue-fighting ride quality sets it apart.

Ride & handling: Superbly surefooted, sprint-bustingly quick

First rides of serious exotica such as the Cervélo are always fraught with not only fear of breakage or accidental damage, but also a real sense of reviewing responsibility. From a cynical point of view most people will buy an R5Ca precisely because it’s so insanely expensive, regardless of ride. However in professional review terms it’s a surprisingly fine line between swallowing too much “Emperor’s new clothes” hype and being decidedly underwhelmed.

In Cervélo’s case sizing is crucial, and while we totally understand the whole high head/dropped stem argument the low saddle Sportive feel is still initially a big shock on such an otherwise performance-perfected superbike. Get used to the position and the R5Ca soon begins to sink its seductive charms into your synapses.

If you keep the power down the R5 just surges forward in a surreal crescendo of speed and rock-solid crank support. It’s even more obvious on climbs, which amplify the super-low weight and suck the top of the climb towards you without vacuuming all the air out of your lungs like normal. Even with the big rings we found it easier than normal to stay seated and spinning up serious pitches, with only proper vertical sections forcing us out of the saddle, where the bike squirts forward like wet soap with every pedal push.

While the thought of a 270g fork is unnerving when hitting dales cattle grids and wet descents at 60kph, the handling is superb too. Road feel is flawlessly precise, but never harsh and chattery, and you have to scream it through corners to detect any difference in the way front and rear halves handle themselves. The thin stays make a difference to comfort too, and while tubular tyres have a slight edge in terms of comfort, the Cervélo still felt sublime when we switched to clinchers to double check. It only appears in those little floated, buoyant freewheel moments into and out of corners or a stretch of pedaling Zen where the bike glides serenely as others rattle, but it all adds up to create a remarkable thoroughbred.

With only the fork providing a tangible performance upgrade, you’d have to be insane to spend the extra £4,000 on an R5Ca frame compared to a standard R5. In terms of owning a piece of state-of-the-art technology that’s both breathtaking and breath saving it outrides anything else we’ve ever tested.

Frame & forks: Clean, thin-walled finish for ultimate weight-saving

The matte black “murdered” frame might take constant cleaning to avoid it looking grubby, but it saves weight and marks out the R5Ca as special straight away. Looking inside the frame when it’s stripped for weighing shows a much cleaner, thinner walled finish inside than normal production frames, with not a trace of excess resin or rippled carbon lay-ups.

The down tube uses an oversized square ‘Squoval’ section and butts on to the Cervélo-innovated BBright bottom bracket shell. This asymmetric design uses an oversized offside bearing for maximum frame and crank stiffness as well as compatibility with most conventional and BB30 cranks. There’s a massive box section behind the bottom bracket for stiffness too, while thickset stays taper quickly away to the dropouts.The seatstays are terrifyingly thin, but the scariest part is undoubtedly the THM fork. It looks beefy enough, but the full carbon steerer plug and kevlar wrap mean it weighs around 30% less than most super light forks.

The down tube cable bosses and front mech plate are fully carbon and the Cane Creek AER headset uses a synthetic bushing rather than a conventional bearing to minimise weight. You still get a replaceable alloy hanger for the rear mech to reduce the chance of a total frame write-off if you drop it on the driveside.

The most radical aspect of the R5 is its shape. For a start our 56cm was bigger than most 58cm bikes. Cervélo also use a tall head tube and front end for extra stiffness. It also makes sense because many of these bikes will end up under sit-up-and-beg style rich recreational riders, with bum up, head down racers catered for by a 17-degree drop stem option. It’s worth checking fit though.

Equipment: Frameset build-up deal

As it’s a frameset build-up deal, discussing the kit on our test bike isn’t really relevant, but we’ve certainly no complaints about the full Dura-Ace suite. Be aware that the slack 72-degree seat angle is designed to compensate for the lack of set back on a super-light straight-up seatpost like the 3T fitted to this.

  • I often get the feeling that the apparent 'ride quality' has more to do with the expectations created by the high price tag than any objective standards. Like expensive wine. It tastes good because if it didn't, you'd have been ripped off (blind wine tests prove this even on 'experts').

    For this money - provided, that is, you're willing to forgo the marketing spiel that comes with Cervelo - you can build a bike that weighs less than 5kg and equally as stiff.

    Dura Ace wheels on a £10k + bike are an embarrassment! What happened to Lightweights? Where are the Clavicula carbon cranks? The all-carbon rear derailleur? The Chris King headset? Nokon cables? Gold anodised rear cassette? One piece hand painted Cinelli bar/stem? Oh, and AX-Lightness or Zero Gravity carbon breaks? No?

    Another mug's product for those that think they can buy the best off the shelf. Like a Hugo Boss suit. Yuck.

  • Even as a guy who rides a Cervelo, this price tag is out there considering the spec.

  • Dura Ace wheels aren't that embarrassing, they didn't seem to hold Cav back any in the Tour. Your list of expensive parts you think should be specced can be subject to exactly the same criticisms you level at the Cervelo frame.

  • Stradisa, totally agree with the first part of your comment, but agree with not_finbar on the rest.

    An ultra-expensive branded product has 'perceived' quality and benefits that a non-branded, but identically-engineered, peer wouldn't have.

  • not_finbar - well said that man ! excellent ...

    stradisa - i have tasted £40 wine that tasted awful

  • Either Dura Ace wheels are embarrassing, or you agree that a £7,500 frameset warrants a pair of wheels barely a quarter of its price.

    As for Cav - it's worth remembering that pros have a minimum bike weight limit. And despite the stickers on their bikes, they often ride with components that are completely different (the 'Shimano', 'Hed' or 'Zipp' sticker over their favourite pair of Lightweights being commonplace).

    And not_finbar, the reason I listed all those exotic components was to show just how ridiculous a decision it would be to buy an off the shelf bike for this price and not even have the freedom to choose your own components.

    Like holidays, 'package' deals sacrifice choice for value. This bike delivers neither. It's expensive and the customer gets little choice in components. What is more, I can guarantee that for at least £1,000 less I could build a bike that weighs less - because once you get into this kind of price range an unhealthy obsession with shaving off every gramme can be the only justification.

    Unless of course you really think the £7,500 frame represents the same level of value as the components on this bike? I doubted it...

  • Why have they made an £11,500 bike 'amateur friendly'? Surely only experienced riders are going to be able to see the advantage in such an expensive bike...

  • CANNONDALE SUPER SIX EVO ANYONE!?!?!? GFAWH GFAWH... what a waste of money this cervelo is... and for nigh on less than half this price you can get a frameset that's a whole snot ball lighter with all the trimmings of a full bike attached!!!???

  • @ chris mcg: this bike is like a rolex watch. Those are not bough by people who need to know the time more accurately either..

    I love super expensive bikes. Firstly, If lots of people buy them, it allows the companies to trickle down technology and compete better in lower price segments. And secondly, I secretly love passing people on bikes like this, saying 'nice bike, man' and then making them watch my 1/10th of their price bike disappear in the distance. It's pathetic, I know, but that sort of thing can make my day.

    Go buy this bike everyone!

  • 11k? Are you on drugs?

  • Sod Lightweight wheels, for 11.5K I'd expect it to come equipped with a Gruber Assist to get the potential buyers' rich fat arses up hills, gravity being the one thing in this world that money can't influence. And not just a standard one either, for that kind of money it would have to be powered by a "Mr Fusion" like in Back to the Future, so you could chuck banana peels and used beer cans down the seat tube, and it would allow you to freewheel up the Angliru. Or, until technology catchs up with that vision, Cervelo could abandon racing bicycles, and make bicycle richshaws, so the super rich can get all the thrill of cycling without even getting helmet-hair.

  • Is this bike bringing back external cable routing into vogue?!

  • For that money I could buy a Giant TCR Advanced SL AND a top notch trail bike. And a present for the wife to keep her busy while I ride :)

  • I think some people may be missing the point of what Cervelo are doing here, this is not a bike that will be in most peoples local bike shop, more a project to showcase what their engineers are capable of building, and in the future the technology will hopefully trickle down into full production models. The insanely high cost is presumably just to re-coup some of the r&d expenditure.

    As for what the reviewed bike is fitted out with, it's largely irrelevant as it's only available to buy as a frame and fork package, as seen in this review is presumably what the distributor had in the warehouse to send out to future publishing.

    Seeing as this bike is largely only going to be purchased by the likes of premiership footballers or bankers then if you do see one out on the road then it probably will be equipped with the top end of everything. Somehow i doubt many will ever see one being ridden though.

  • In the car industry it called a concept car its not new and they don't try and sell them to the public. Make a couple and show them off at the bike shows.
