Poshbikes' 4.26kg Olympia 849 superbike

how long does a carbon chainring last ?

A few years ago Gunter Mai spent a fortune building/customising a 3kg, 6sp road bike. The custom Lew wheels alone cost £10,000; now you can buy an off-the-peg 4.26kg machine with Di2 gruppo for eleven large. I call that progress.

Raleigh actually a true gentleman. I think you mean guyz2010 rather than Raleigh. The name under the post is the one to look at rather than on the top of it, so guyz2010 - which I think is the year that his opinions date from.

Raleigh - why must you be so offensive? I am close to 55,I own some Assos and I own a couple of very very nice bikes, one of which is very light indeed. I enjoy every second I spend riding it. I may not be as fast as you (I assume you are really fast) but I am pretty competitive and I can hold the wheel of people 20 years younger than me. More importantly I adore the time I spend on the bike, which is around 10+ hours a week (I assume you will spend much more than that in the saddle) and having worked hard all my life and looked after my kids, I don't feel bad about owning a good bike. In fact, I feel great about it.

By the way, I think you mean "pot bellied" rather than pop-bellied.
I do tend to put a kilo or two on in in winter. Obviously, you won't do that.

Good for maybe 1 ride.

I've heard the 'my bike cost more than my car' boast before but this is getting into 'my bike cost more than my house' territory

That saddle weighs 35 grams?! Those wheels weigh less than 800 grams!? Etc etc. Well I for one think it's gorgeous.

it sounds lovely is a more mechanical way!

Would save even more weight if they integrated the seat post.

Mind you combined with that seat that would be one cranky ride that would have you improving your out of the saddle skills.

Are white hoods lighter than black? That's the only reason I can think of for them being there.

The rear hub gets its name from the fact the freehub incorporates magnets instead of conventional metal springs. It not only saves a load of weight but also gives the freehub a unique sound.

How intriguing. Any chance of a video of it in action so we can see/hear how it works?

It's good to see what can actually be done. We know that 6.8 is just arbitrary these days, but I didn't know how low you could feasibly get the weight.

It would be interesting to see some some sort of generic price/weight curve - vagaries of kit choices aside, of course.

That saddle, though, looks terrifying.

why is it you people cannot just accept this for what it is? This is poshbikes pushing the boundaries of what is possible as a purely technical exercise and surely it doesn't matter who owns it.

But does it have lugs for mudguards and panniers? If not that could be a deal-breaker for me.

The link's expired, but see my forum topic from last year:

you could probably cut those brake cables shorter, and file those brake pads down a bit. That would save you 2% #marginalgains

Would be interested to see a ride report. On a non-windy day of course.

Apparently you don't get tyres either. I suspect you could put some ultra light silk tubs on it ?

I couldn't take an 11k bike out. I'd be so paranoid about dropping /breaking/ scratching it.

Before we delve into this build, we'll warn you that the frame alone costs £3,000, and you can get a Shimano Ultegra 11-speed build for £3,300,

Am I reading this wrong, or does that mean you can get an Ultegra groupset, wheels and finishing kit for an extra £300?

Pedals and bottle cage(s)?

I really couldn't buy this bike - aside from not having £11k to spare, what excuse would I then have if overtaken uphill by someone on a Raleigh Shopper?

I quite like that saddle actually - there wouldn't be any friction, although I might be tempted to put a gram of double sided tape on it

hmmm this is why weight obsession is not so good. i think it looks a bit erm cheap..

the post stem bars and cranks are really ugly, would rather have heavier but aspthetically pleasing bits and the wheels look odd

a great excercise in what can be done but not my cup of tea at all

Wonder if the weight weenie rides naked to keep everything down, maybe has tools and spare inside a helium balloon?

Yeah that saddle would have to hurt almost as much as the price tag

At least there is somewhere you can easily tape a spare innertube.

All looks fab, except for the saddle!
