Polished rims look sweet.

Yep, nice shiney thing, but it's capable - not only good looking

It deserves embedding

holy mary sweet mother of god now that is what I call a nice bike

Where did you find this singular peregrine? any more? I've always thought they looked brilliant

not a singular (note the fastback stays and track ends) - take a look here for peregrine pics...

^ Handy!

Sorry about the gears??! BS! Gimme that C-record De Rosa!

+1, the De Rosa is the stand-out bike from that bunch; the rest of them, meh.

Exactly, i'd rather have that bike than a fancy build NJS one..

        **Mad Fiber carbon road wheels – First look**

Mad Fiber's first product is this road wheelset

Showing 1 of 6

I didnt know you could just cut carbon like that against the direction of the fibres

You can, and Fibrelyte do it all the time for their carbon fibre chainrings etc., but it's probably not the best use of the material for making spokes.

In fact, carbon fibre is a dumb material choice for spokes however you use it. Steel is better, simply because the spoke a pretty much a pure tension element, and steel has a high Young's modulus, allowing adequately stiff wheels to be built with a smaller total cross sectional area of spokage than other common engineering materials. Since the spokes contribute hugely to the aerodynamic drag of a wheel, getting the spoke cross section minimised is half the battle in making a fast wheel. The trivial weight penalty of using steel compared with lower density alternatives is massively outweighed by the aerodynamic gains from thin spokes.

now this is ^ more like MT's post, not that ^^
lol

Too big.

I bet you hear that a lot!

Total cross-sectional area is for the most part irrelevant if they are aerodynamic spokes though ( but I'd agree with you completely if they were cylindrical). This only really affects skin friction, and the reduction in form drag by making them aerofoils far outweighs this small increase in skin friction. Cross winds would suck though.

I think you are to easily excitable.

Now I can sell it with a seal of approval :-)

GT by Yamaguchi

i really love those frames, and the paint job is so over the top i like it.

i would definitely ride a stars n stripes frame

Total cross-sectional area is for the most part irrelevant if they are aerodynamic spokes though

That's true, inasmuch as a HED3 is much better than a wire spoked wheel with the same rim and a much smaller area of round wire spokes, but the default aero steel spoke (Sapim CX-Ray) has pretty good aerodynamic performance across a range of yaw angles, and you only need 16 of them to make a usable front wheel. The MadFiber spokes have square corners, so they will have a lot of wake drag for their thickness, and will stall at a very low yaw angle. Just a bad idea all around. At least Lightweight manage to make their spokes more or less elliptical, and line up most of the fibres with the stress direction.

^^ at those GT/Yamaguchi, could somebody tell me why did they have to build this tall seat tube all the way up to the saddle? super-stiffness? to demonstrate some extra degree of customness?
i wonder what's the size of that frame (now that i know who the owner is... hahaha)

I think the are modern equivalent of lo-pros, that's why. You should ride them in an aero position.

but that doesn't necessarily mean the seat tube had to be that long does it?.. i don't get it

It's to keep little people at bay.

Saw one of these in the flesh today... Absolute cumfest of lightweight skinny machinery... Not my usual cup of tea but it's gorgeous in the flesh...

Well fit!
