Rapha, nice but a bit pricey?

ah, but it will, surely. the same miniscule aero gains etc ( obviously not with Di2, but you know what i mean) will still benefit the fat banker/me, but their/my overall time will still be very slow. but it will be fractionally less slow, that's the point.

not so you'd notice

yes, well, you wouldn't notice it on cancellara either.

It's lighter too. Eventually they'll come up with technology so awesome it will negate my weight disadvantage and my awesome power will be used to smite skinny fucks left and right. You just watch..

And fat guys will win the Tour, right?

Mmm...

The bible says so..

You failed maths at school, right?

power to weight ratio.

how you beat the skinny fucks is up to you, most of your weight is in your legs and core anyway, the bits that provide the power. It's not like you are carrying around big shoulders, or a massive head. Although funnily enough, cyclists with big heads are usually very good.

Yes, power to weight ratio. So, I produce x power, if I reduce my weight using bike tech magic I go faster. It's almost as good as voodoo.

is there a graph showing average GC placement plotted against hat size?

the weight of the bike? oh, I thought you meant trimming the hippy booty

If there is I'd like to see it.

I've seen that bloke who won that tour de france thing, and his head is massive, comparatively.

As if that's gonna happen. I need something like a Helium-filled bike but 10000x more effective.

With an atomic weight of approx 1, a bicycle filled with hydrogen would be about a quarter of the weight of a bicycle filed with Helium, having an atomic weight of approx 4.

With an atomic weight of approx 1, a bicycle filled with hydrogen would be about a quarter of the weight of a bicycle filed with Helium, having an atomic weight of approx 4.

For the purposes of calculating buoyant forces and the like, you need to consider the molecular weight of the gases, not the atomic weight. Helium is just He; Hydrogen is H2, so Helium only has twice the molecular weight of Hydrogen.

However: the relative effect of the two gases on the weight of an object they're filled with differs by much less than a factor of two, since air is so much heavier than both hydrogen and helium, and the buoyant force of an object filled with either gas is the weight of the air minus the weight of the gas. It's something like an 8% difference, in fact.

Think about holding a balloon underwater. The buoyant force of the balloon is the weight of the water displaced, minus the weight of the air in the balloon. You'd hardly notice the difference if the balloon contained pretty much nothing at all instead of air.

Just met Chopsicle (sp?) riding along Tower Bridge. He works for Rapha. He agreed, indeed, it's a tad expensive.

On another note you shoulda seen my steed next to his Columbus framed rapha'd Enigma...

I saw the Enigma/Rapha bike in New X last night being ridden into Sainbury's. Which is quite a reasonably priced supermaket.

I wrote to ask for a job at Rapha.

They said no.

Have you slagged them off on here before? :p

I thought everyone had ignored my post like Rapha ignored my email.

Back to the pricey topic;

£2.5k to spend a week cycling the high mountains with DJ? I'll pass. :p

Sorry Balki. I have just seen this and am astonished that you, as a scientist of some experience, could write such nonsense.

A bicycle is not merely what exists between the tubing but also consists of the tubing itself. Therefore is a bicycle filled with air weighs x one would have to determine the weight of the bicycle components if placed into and "filled" with a vacuum (although the bike would collapse which is why I used the words "bicycle components" and not "bicycle") to determine the base weight of the bicycle and then ascertqain how much gas would fill the tubes and the relative weights of helium and hydrogen.

Most of the weight will come from the carbon/metal and other solid componets rather than from the gas that fills them. In other words the weight saving by filling a bike with helium or hydrogen would be minimal and the difference between the two would be really small.

Rapha hydrogen would be good hydrogen but pricey hydrogen.

Sharkstar/Cliveo,

The conventional scientific theory you cite is flawed.

My own groundbreaking experiments support my claim. I provide the following graph as evidence.

rapha is nice if a little pricey.
i have been using their stowaway jacket recently, it cuts out the wind and does a good job keeping off the rain.
it's bright orange sets it apart from the usual fluro yellow peleton attire and has received numerous plaudits from my peers.
a top quality cycling specific garment.

i imagine rapha hydrogen would be given off when expensive metals react with expensive acids.

I go misty eyed when thinking about their black and white merino wool jersey, with front pockets and a neat collar. It's nice if a little pricey.

i fancy one of those, just have a hard time swallowing the price tag.

would you say it's wind-cheatingness is enough that, if paired with a warm winter jersey ( rapha, natch) and base-layer, it might negate the use of a winter jacket, on all but the coldest days?

But nimhbus, you can get £4 off postage at the moment.

How can anyone, let alone a grown man, resist that?

i'm waiting for the next sample sale..
