nice! how much is it though?

Stewie Griffin

Only snakes need apply. I can imagine hearing a few scary noises from it just from me sitting on it.

Err, your browsing the Triathlon Gear Guide? Something you want to confess NapD?

Saddle looks comfy!



I'd swap it for one of these and double the weight!

Percy Vera

yeah, but is it stiff?

The Brooks looks like something you'd find in the sort of brothel favoured by Max Mosley.

OK, who wants to be first to point this thing downhill and see how it handles under brakes from 100 kays into the hairpin bend.

Anyone?



Anyone?

It wouldn't get that far with me on it Wheelspinner. If someone saw me a few seconds after I'd got on it they'd be wondering what that funny looking man was doing stood over a pile of bent tubing...

I've eaten pretzels that weigh more than that thing..

That goldie lookin chain is screaming ''bling'' at me - do you ride it or do you wear it?

I'd ride it!

I only weigh 53kg!

Er is the helmet on backwards?

No, I think it's his head that's on backwards

But to be honest, those transition areas are pretty hectic places, it's pretty good he's got his shoes on!

Ok ok, I admit it, that's not really me.

THIS is me...

Wonder how much it would weigh as a fixed gear. Not that I'm particularly into fixed gears (despite owning one) or that it would improve the functionality of the bike in any way, I'd just like to know exactly how light a working bicycle can be.


Rear brake - AX Lightness Orion caliper 47g + pads (another 20g perhaps)
One brake lever - I don't know what brakes they used, but the lightest levers I can find are SRAM Carbon ones at 100g/pair. I imagine they've modified their levers to be even lighter, so I'd estimate the weight of one lever to be 30g
BTP Downtube shifters - 9g/pair
Rear derailer SRAM Red - 100g
Rear cassette - which is presumably SRAM Red too, 155g
Front derailer Campagnolo Record Titanium - 72g
Crank - prototype 'Mythic' - just estimate removal of inner ring, maybe 30g

Plus you'd save the weight of 1/3 less chain, plus three less cables. I don't know what the chain is, but the FSA Superlight is one of the lightest you can get, and that weighs 250g, so say the shorter chain saves another 80g or so.
A Campagnolo inner brake cable weighs 25g, so that's another 25g saved. Plus a length of outer, perhaps another 25g. And there's two lengths of gear cable (which is thinner than brake cable) and a very short section of outer, so call it another 40g. And there's also the weight of all the cable stops and threaded derailer mounts and stuff that's no longer needed - perhaps another 25g.

I can't find weights for many aluminium fixed sprockets, but the VeloSolo 17t one was tested at 24g. And we'll need a lockring - Token make an aluminium one at 5g. I'm making an assumption that a track hub can be found or built at the same weight as a normal freehub - I think they could be made lighter but it would be more of a guess than an estimate so I'm going to just keep the weight of the rear hub the same.

So overall that adds up to 658 grams, plus 29 grams for the fixed sprocket and lockring, gives 629g total weight saving. The bike would weigh 2,071g. Which is absolutely astonishing.


EDIT

I think I've overestimated the weight of the cables a bit. But then I've underestimated the potential weight of a fixed rear hub. Maybe it cancels out.

I think if I was one of the photographers, I'd want more than a traffic cone for protection! Maybe a Tri with the trasition area through the Arenberg forest might be fun?

If you hit one Surrey pot hole and that thing is gonna br toast. I wonder how much the owner weight and how often he rides it.

How much free time do you have ?

freehub

Some novice will buy this bike and think they're superman only to be getting overtaken by people on MTB's or heavy road bikes. Then he'll smash it when he chucks it onto the grass verge in a paddy.

Sheptastic

You on the waiting list then Will?

dodgy

A lot of people on this thread seem to know how strong the bike is.
