    I'm sure the reviewer didn't stop every 100 yards to re-set the road surface type. He got within the margin of error across many different rides.

    Just accept it folks, this shit works. It has a few 'drawbacks' (read: stuff you have to do differently but that is not 'hard'), but solves some other common issues with power meters - like having to swap your cranks, pedals, or have multiple compatible-wheelset bikes.

    Who rides in the same position though? I spend most of my time on the hoods, but climb on the tops and descend or go flat-out on the drops (don't most people?). I'd like it to work because I respect anyone who can code a decent algorithm taking in account this many variables.

    When will someone develop and market a lightweight and indescrete front and rear facing video camera wit a lot battery life an a loop in record in system. Either for fitting to th bike or incorporated into helmets or front and rear lights units. Surely no that complicated or difficult. Make the compulsory and make sure all car van and lorries and make sure they know bikes are carrying them and I predict drivers would instantly become more considerate.

    An Australian Silver Medallist swimmer returned a positive to this a while ago and it was revealed it was in a medication a doctor had prescribed for a chest infection. He got suspended for 4 months.
    I guess it is like horse racing, were he wasn't at fault, but was presented to races with a prohibited substance, so they have to do something, unless they were nobbled.

    I will give benefit of doubt till case is heard. This news really did saddened me when I heard, as I am a big Greenedge fan.
    I have to admit I commented to fellow Aussie cycling friends that Impey was absolutely flying early this year.
    Lets hope it was all down to hard work Sad
    GOOD LUCK Daryl Worried

    I came down to London in 2002. The difference then between a Crane Operator up in Yorkshire and a Crane Operator down here was about £25k a year. London and the South East are the massive engine that powers the UK economy. That is a fact whether you like it or not!

    That's very selective, it can also induce seizures and diarrhea as well as anti inflammatory effects (like that of iburprofen) and can be found in tea.

    On its own it's not necessarily the sort of thing you would want to pump yourself full of as an athlete, you certainly wouldn't want to unnecessarily put your heart rate up when doing hours worth of a tour stage or race. After a quick Google it looks like research has been done (which is why the likes of WADA have come to the conclusions they have..) on whether or not it's actually beneficial to athletes and research, on the face of it, appears conclusive in the view that it's not.

    Quit the chinstroking and move on dude. Impey's been done for something illegal, there's something to talk about. Smile

  • Improve performance/speed how1 year 4 weeks agoYeah, the North Downs ridge

    Yeah, the North Downs ridge is great, there's loads of good climbs - some may hurt you more than others though. I guess for height and profile similar to Toys, give Brasted Chart a go (the gentle side of Toys Hill). Or do Box itself, of course, but it's not a hard hill... pretty gentle slope, just grind your way up. Leith is a smidge harder, but people are going so slowly up it on RL100 that you'll be doing your best to pick your way in between them.

  • Orica-GreenEdge's Daryl Impey tests positive for banned diuretic1 year 4 weeks agoWe'll see what comes of this,

    We'll see what comes of this, if I have read everything that has come out so far.

    He got tested on 6th February, tested positive for Probenecid by South African anti doping body, yet when he was tested on 7th and 8th February it was not found.

    Then when his B sample was tested it still contained Probenecid.

    I know a bit about Probenecid because quite a few of my family have kidney issues. It is used to prolong the effects of certain medications and prevents them just flooding through your body and out in your urine.

    So as a masking agent it is perfect, depending on the type of drug you take. It will increase absorption into the body of the drug and prevent it being wasted out in urine. Unlike most masking agents which just increase your urine output, thus diluting the amount of drugs your produce in your sample. Probenecid keeps the drug in your body, preventing it from getting into your urine.

    The problem with it, Probenecid only lasts around 4-6 hours. so unless he was particularly stupid and took it the morning of the race, I find it hard to see how it was still present enough in his sample to make it an illegal dose.

    That's because they are not cable adjusters, they are spacing the cable housing (which looks like Nokon, therefore machined metal segments) off of the frame to prevent the cable housing rubbing. The 'adjusters' or spacers are most likely a segment of the cable housing with a soft polymer moulding added.

    Hi magslmac pleased you got your order away. I wonder (being new to cycling) can the shop offer you a proper bike fit to get you 'on the road' correctly before you pick up the bike?

    I've made the mistake of purchasing my bikes (correct size) but the finer points of correct seat post and saddle positioning, handle bar set up is very important and ignored by most cyclists. For me coming back into cycling I struggled over the last few years with lower back, knee issues. A proper bike fit helped me enormously and I have no niggly issues any more.

    What you said rings true for everywhere else in the UK, just not London.

    Yep, you're right, it does go direct from the treasury, the GLA is just responsible for negotiating that funding. Doesn't change any other point, London is a large net contributor to the rest of the UK.

    Matt eaton wrote:
    All looks good but I can't figure out why campaigns for utility cycling keep piggy-backing on cycle-sport events.

    We already have a strong culture of sport and leisure cycling in the UK and have done for many years. Has this translated into mass uptake of the bicycle as a form of transport? No. Do people involved in cycle-sport even use bikes to travel to races etc? On the whole, no. I race BMX and know loads of kids/parents who are involved in the sport; do you think the kids ride to school? Of course not.

    It's a bit like piggy-backing a car race to run an anti drink-driving campaign. Yes, both involve cars but it's not really relevant.

    The point I'm trying to make is that we need to start thinking about sport cycling and utility cycling as two quite different things which carry quite different benefits to participants. It's as distinct as the difference between walking to the shops and doing a 5km running race. Nobody uses the London marathon to encourage people to make more journeys by foot. Without making the distinction cyclists will always be viewed as lycra-wearing weirdos by the majority.

    You're right - it is a highly important distinction that too few people realise, and the fact we keep discussing 'cycling' as if it's one single activity with one single purpose is at best misleading and a worst brain-washing millions of people into believing that making a city 'cycle-friendly' means turning it into a velodrome rather than an Assen.

    However, I'm happy to see utility cycling piggy-backing on anything it can get at the moment. Also, given that BC deals with everything from getting kids to school to Olympic champions, I can understand their approach in capitalising on something that has the public's attention.

    In short, I strongly agree with you about the importance of the distinction, however I think the TdF is too good a platform to pass up. There are more similarities between basic utility cycling and the TdF than any other major event I can think of. Until we get some sort of globally publicised 'trundling around town' event, anyway.
