  • Otley residents accuse Cambridge of putting on a 'flat and boring' Tour reception… though it hasn't happened yet1 year 7 weeks agoWell having been on the route

    Well having been on the route yesterday, and seeign the coverage on tv, I don't think there was any lack of support for the tour, especially having seen how packed Saffron Walden was and hearing Phil Ligget getting emotional at the sight of people crowding 50-100 deep. I'm glad I went to Great Waltham, relatively small village with a little bit of a hill meant they came through (a tiny bit) more slowly.
    It was still jam packed with people, and the atmosphere was incredible, I think everyone's done the country proud over all three days.

  • Bell launch ‘fastest’ aero helmet: Star Pro + video1 year 7 weeks agoWell I just recently arrived

    Well I just recently arrived at the start line in a local club ten TT having left my (non aero) helmet plus goggles in the car boot. At seventy six I blame onset of short term memory loss, however I went 29 seconds quicker on a windier evening than the previous week. My moderate time was impressive only to me as I pondered the marginal gains of riding with a bald head versus helmet, wearing a helmet is not something I do as a general rule, but do so in TT's to placate the pro helmet brigade.

    Without all your body measurements it's difficult to know for sure but it seems to me as I suggested in my first post, that your bike is too big for you. I'm 5'11" and a bit and all my bikes have 695mm of reach from seatpost to bar (For example: 565mm top tube + 130mm stem) and I'm fully stretched out with average arm length and good flexibility and I sure wouldn't want to go any further forward. In comparison you've got 690mm yet are an inch and a half shorter than me. You might have monkey arms though but from what you've suggested I think the size is the issue. Not you being rubbish.

    You could try fitting a 90mm stem but I think it's an elastoplast for a bullet wound. I would suggest looking at going to a proper bike shop and look at getting a smaller bike. If the saddle is adjusted correctly your knees will feel just as good, you'll be more comfortable and confident on the bike.

    A good shop will let you test ride. Do that and see how a smaller frame feels.

    Who are you? Dave Brailsford's cheerleader? Try not to be so condescending.

    I would give Wiggins a chance to rehabilitate himself. He seems to have made a genuine effort to try to work with the system. To be honest I don't think Wiggins did very much wrong except be second best to Froome. The bonus affair was unseemly, but to be fair to him Froome did not seem to want to play his role of playing second fiddle when Wiggins was nominated the GC contender. Perhaps he has burnt all his bridges, but if this snub doesn't tell him exactly where he lies in the pecking order I don't know what does....but given the rumours over Garmin I think he has taken the hints.

    As for Sir DB: this seems to be more about his ego than anything else. Why couldn't a French contender rise out of a French team? Or do you still think it is a matter of 'marginal gains'. Nice PR, but I can't see Sky doing things which BMC, Astana and Trek do. Big names, big money. If a French rider becomes a credible Tour contender then it's all grist to the mill.

    Colin with all due respect wiggo was not part of the conversation , I was answering why he shouldn't be there .
    As for a French rider going to SKY ....can't see it , it's more likely DB will go to a French team now he's cut ties with BC

  • Bell launch ‘fastest’ aero helmet: Star Pro + video1 year 7 weeks agoFJM1002: The human head seems

    FJM1002: The human head seems pretty aerodynamic to me in shape. At least, not significantly worse than road helmets. It's hard to find studies comparing helmets to headforms (most are helmets against helmets). Apparently Kyle Chester did research on this, but I can't find relevant ones online. Sheldon Brown's site has a report on his results though:

    http://www.sheldonbrown.com/rinard/aero/aerodynamics.htm

    A pure aerodynamics (i.e. pre-helmet-rules, no need to care about padding, very thin) TT helmet gives a 2% improvement over a bald headform. An ANSI approved TT helmet (old Bell Stratos) *increases* the aerodynamic drag by 1.3%, compared to a bald head. This means the human head (bald at least) lies somewhere between an ultra-thin, pre-helmet-rule TT helmet and a post-rule TT helmet. This means the (bald) human head is actually pretty damn aerodynamic.

    The problem is the drag equation, the force of the drag F = ½.ρ.v².Cd.A. The padding and foam required to meet crash tests increases A - by a lot. For a road helmet, my back of the envelope calculations suggest upwards of 20%. So, just to break even, the helmet needs to *reduce* the Cd by proportionally the same amount - by 16% (i.e. by 1/1.2). That's a big ask.

    Now, hair is very unaerodynamic, and according to the report on Kyle Chester's results, the ANSI approved TT helmet has less drag than a head with hair. However, like I said, that's what a cycling cap is for. Next, road helmets are always going to be worse than pure TT helmets. Even aero road helmets. It's just an inescapable fact of the need to vent heat.

    So to summarise:

    - It seems the (bald) human head compares quite favourably to TT helmets, even the now "illegal" 'pure' aero helmets. Though, also, there's not much data out there.

    - Hair is unaero. A decently fitting cap should fix that and get you most of the way back to the aero performance of a bald head, I would contend. The cycling cap also costs just £3, rather than £200+.

    - Venting in helmets is unaero (lots of helmet to helmet comparison studies out there showing this), however for any helmet you'd want to wear for longer than a TT, you tend to want venting..

    midschool: I didn't comment on safety aspects, only on aero performance. Note that the manufacturer in this article isn't marketing this helmet for its safety, only on aero performance. Indeed, it's a rare helmet manufacturer who makes any strong claims about safety (ever wonder why?).

  • Bad balance on bike (wrong frame size or rubbish rider)1 year 7 weeks agoYou would be surprised in the

    You would be surprised in the difference a few cm make. When I bought my road bike I thought I was 5ft 10 so my LBS tried me out with a 56cm frame. They could see I wasn't totally right on it and I did feel a bit out of kilter and stretched, but I assumed that it was just me not being used to it and that all the info I had read about my height meant it should have been a 56cm. However I jumped off and they measured me whereupon I discovered I have been lying to myself for years and that I am only 5ft 9! They suggested a 54cm and it felt much better (so much so I never changed my position hence my recent forum post about a seized seatpost!). Changing the saddle position on the smaller frame may have worked out better for your knees, as opposed to the larger framesize. (Remember though that my 54cm and 56cm are based on Specialized measurements-each manufacturer measures their bikes slightly differently so a 58cm Carrera could possibly be a 56cm in another brand and as I have already pointed out-that few cm could mean a big difference).

    Could be carnage if it's wet. In the GCN preview video, which I think was only filmed a few days ago some of the puddles on the pave sections were enormous.

    Going to be an interesting stage wet or dry. Last time the Tour went over the cobbles the front group at the finish was an interesting mix; classics riders like Hushovd, Thomas & Cancellara, but also GC guys: Evans, Andy Schleck & Hesjedal.

    We will have to wait to see which of the specialists get the freedom to go for the win and which will be forced to shepherd their team leaders.

    Hi, first post on here. Regarding Chinese carbon frames ect ect . I have built 4 bikes in total now. When building my first I was extremely nervous and thinking about how poor the service and quality of the product could be. However, when a friend (who lives in china however is british) explained to me how it actually works I had no doubts. Basically the big brands work with the asian, Chinese, Thai OEM whoever it will be and they will make there own moulds. The OEM can't use that mould to sell bikes from there own company bedcause of copyrights or watever it is, however the OEM make there own moulds and use the exact same carbon and materials, and its the exact same men/women making the frames. So for the people who are worried about the bike breaking ect , it has just as much chance as a big brand make. That's when warranty comes in, there is a few sites and OEM that give 2 years warranty, the only problem you will have is it might take awhile due to the fact you will have to post the bike to the other side of the world rather then pop down your local bike shop. With the right tools and knowledge you can easily build a bike for around £2000 which has the same performance as a £6000 bike from a shop plus you can add your own custom design ect and its a one off.

    Ok but it's *their* own moulds ... not "there". You made that mistake 3x in the same sentence.

    Calling this film "beautifully crafted" is a bit of a stretch. Not a bad documentary by any means, but loses its way in the second half. In particular, the constant reuse of the 'dramatic reconstruction' doping footage at the end got a little old.

    As a film, the Armstrong Lie is much better, and I could easily recommend it to non-cycling fans. This movie is best left to those who already have a passion for the sport.

Whether it's sunbathers coming into the fields where I walk my dog so I have to put it on a lead, where were they on those rainy winter days? Or some teenage girl getting a selfie of the tour so she can show how interesting she is, blocking my view of action.

    Luckily most of the crowds at the top of Holme moss were cyclists and there was a really good atmosphere beforehand, I imagine most who drove there had to park at the bottom of the hill and couldn't be bothered to walk to the top.

    Unlikely, the OPQS boys seem to be really struggling. They don't appear to have got themselves in a position to deliver anyone to the front. That's the reason Cav crashed. The train didn't deliver him and he got boxed. On today's showing nothing has changed. I can't see them doing anything in a normal sprint and so they have to hope for a breakaway or Kwiakowski doing something on GC, which is remote. Cav really was plan A and all that has gone out the window.

    I think a Tony Martin TT will also be a tall order.
