Was it something about carbon bikes coming nowhere in the 1914 Giro d'Italia?Are we all still arguing?
Let me get this right, the basic points are that an old bike with its inherent oldness, is factually older than a new bike that is newer and, therefore a new bike cannot be compared to an old bike because its newness makes it un-old...ergo, to whit, ad nauseam, Cogito Ergo Sum, the old bike is older than the new one.
have I got that right?
so, sorry, what are we arguing about?
Of course they aren't mutually exclusive. To be competitive you need both, to an extent. But some people do the former without bothering with the latter. It's their money of course, but it's just an observation. I'd hate for people with low disposable income to be put off competing in time trials and road races because they can't afford £8k bikes.
Go for it..
Great - if you know the answers to my questions, let's hear them? Your thoughts on 'better bearings' would be particularly welcome...
Yup. Citius, if your problem with my previous post was that you don't think bearing friction losses amount to very much, I'd agree, friction losses overall in the transmission are fairly small, and the difference between different bikes therefore even smaller. But there still is a difference.So, 'better' bearings, in the sense that they roll with less friction. As that's what a bearing is designed to do, along with other roles, like shaft/axle support.
Anyway, bearings of old were produced using steel wire, cold welded to create balls. These then fitted into a race and provided a rolling surface. Simple. Yet, because of manufacturing techniques, these bearings could and would become pitted, would seize and generally be shite. So what did they do? Well, apart from using quality materials, computer aided manufacturing to ensure completeness and roundness, they made the whole thing out of ceramics. This requires little lubrication and offers 1/10th friction of a steel bearing. They also make hybrid bearing, which retain the steel outer and raceway. Are they worth it? For an amateur on a pushbike? No. For gaining that 10% advantage at professional level, where cost is no problem? Yep, why not.
Perhaps we could turn the question on its head, and ask whether a faster bike would be better.Apparently, we are arguing about whether a better bike would be faster.
Do you have any proof to back up your claim of pointlessness, I have a friend who once knew a girl that babysat for a mates hairdresser who said that your comment was 100% proof that you had a point.I just thought I'd make a completely pointless comment on a completely pointless thread. There, that was nice.
I recall reading that Sky removed the seals from the hub bearings of Wiggin's time trial machine, on the basis that for that distance you don't care how much water gets in, but you want to remove every possible source of friction, even a bit of rubber sliding on metal at small radius. No doubt a very marginal advantage, but an advantage nonetheless.
